# T1002 - Data Compressed
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1002)
<blockquote>An adversary may compress data (e.g., sensitive documents) that is collected prior to exfiltration in order to make it portable and minimize the amount of data sent over the network. The compression is done separately from the exfiltration channel and is performed using a custom program or algorithm, or a more common compression library or utility such as 7zip, RAR, ZIP, or zlib.</blockquote>
<blockquote>An adversary may compress data (e.g., sensitive documents) that is collected prior to exfiltration in order to make it portable and minimize the amount of data sent over the network. The compression is done separately from the exfiltration channel and is performed using a custom program or algorithm, or a more common compression library or utility such as 7zip, RAR, ZIP, or zlib.
Detection: Compression software and compressed files can be detected in many ways. Common utilities that may be present on the system or brought in by an adversary may be detectable through process monitoring and monitoring for command-line arguments for known compression utilities. This may yield a significant amount of benign events, depending on how systems in the environment are typically used.
If the communications channel is unencrypted, compressed files can be detected in transit during exfiltration with a network intrusion detection or data loss prevention system analyzing file headers. (Citation: Wikipedia File Header Signatures)

#### Group Policy Preference (GPP) Files
===Group Policy Preference (GPP) Files===
Group Policy Preferences (GPP) are tools that allowed administrators to create domain policies with embedded credentials. These policies, amongst other things, allow administrators to set local accounts.
 
These group policies are stored in SYSVOL on a domain controller, this means that any domain user can view the SYSVOL share and decrypt the password (the AES private key was leaked on-line. (Citation: Microsoft GPP Key) (Citation: SRD GPP)
 
The following tools and scripts can be used to gather and decrypt the password file from Group Policy Preference XML files:

See [Kerberoasting](https://attack.mitre.org/techniques/T1208).
See Kerberoasting.
#### Plaintext Credentials
===Plaintext Credentials===
After a user logs on to a system, a variety of credentials are generated and stored in the Local Security Authority Subsystem Service (LSASS) process in memory. These credentials can be harvested by a administrative user or SYSTEM.
 
SSPI (Security Support Provider Interface) functions as a common interface to several Security Support Providers (SSPs): A Security Support Provider is a dynamic-link library (DLL) that makes one or more security packages available to applications.
The following SSPs can be used to access credentials:
 
Msv: Interactive logons, batch logons, and service logons are done through the MSV authentication package.
Wdigest: The Digest Authentication protocol is designed for use with Hypertext Transfer Protocol (HTTP) and Simple Authentication Security Layer (SASL) exchanges. (Citation: TechNet Blogs Credential Protection)
Kerberos: Preferred for mutual client-server domain authentication in Windows 2000 and later.
CredSSP:  Provides SSO and Network Level Authentication for Remote Desktop Services. (Citation: Microsoft CredSSP)
 
The following tools can be used to enumerate credentials:
* [Windows Credential Editor](https://attack.mitre.org/software/S0005)
* [Mimikatz](https://attack.mitre.org/software/S0002)
 
* Windows Credential Editor
* Mimikatz
 
As well as in-memory techniques, the LSASS process memory can be dumped from the target host and analyzed on a local system.
 
For example, on the target host use procdump:
* <code>procdump -ma lsass.exe lsass_dump</code>
 
Locally, mimikatz can be run:
* <code>sekurlsa::Minidump lsassdump.dmp</code>
* <code>sekurlsa::logonPasswords</code>
#### DCSync
===DCSync===
DCSync is a variation on credential dumping which can be used to acquire sensitive information from a domain controller. Rather than executing recognizable malicious code, the action works by abusing the domain controller's application programming interface (API) (Citation: Microsoft DRSR Dec 2017) (Citation: Microsoft GetNCCChanges) (Citation: Samba DRSUAPI) (Citation: Wine API samlib.dll) to simulate the replication process from a remote domain controller. Any members of the Administrators, Domain Admins, Enterprise Admin groups or computer accounts on the domain controller are able to run DCSync to pull password data (Citation: ADSecurity Mimikatz DCSync) from Active Directory, which may include current and historical hashes of potentially useful accounts such as KRBTGT and Administrators. The hashes can then in turn be used to create a Golden Ticket for use in [Pass the Ticket](https://attack.mitre.org/techniques/T1097) (Citation: Harmj0y Mimikatz and DCSync) or change an account's password as noted in [Account Manipulation](https://attack.mitre.org/techniques/T1098). (Citation: InsiderThreat ChangeNTLM July 2017) DCSync functionality has been included in the "lsadump" module in Mimikatz. (Citation: GitHub Mimikatz lsadump Module) Lsadump also includes NetSync, which performs DCSync over a legacy replication protocol. (Citation: Microsoft NRPC Dec 2017)

### Linux
Detection: Common credential dumpers such as Mimikatz access the LSA Subsystem Service (LSASS) process by opening the process, locating the LSA secrets key, and decrypting the sections in memory where credential details are stored. Credential dumpers may also use methods for reflective Process Injection to reduce potential indicators of malicious activity.
#### Proc filesystem
Hash dumpers open the Security Accounts Manager (SAM) on the local file system (%SystemRoot%/system32/config/SAM) or create a dump of the Registry SAM key to access stored account password hashes. Some hash dumpers will open the local file system as a device and parse to the SAM table to avoid file access defenses. Others will make an in-memory copy of the SAM table before reading hashes. Detection of compromised Valid Accounts in-use by adversaries may help as well.
The /proc filesystem on Linux contains a great deal of information regarding the state of the running operating system. Processes running with root privileges can use this facility to scrape live memory of other running programs. If any of these programs store passwords in clear text or password hashes in memory, these values can then be harvested for either usage or brute force attacks, respectively. This functionality has been implemented in the [MimiPenguin](https://attack.mitre.org/software/S0179), an open source tool inspired by [Mimikatz](https://attack.mitre.org/software/S0002). The tool dumps process memory, then harvests passwords and hashes by looking for text strings and regex patterns for how given applications such as Gnome Keyring, sshd, and Apache use memory to store such authentication artifacts.</blockquote>
On Windows 8.1 and Windows Server 2012 R2, monitor Windows Logs for LSASS.exe creation to verify that LSASS started as a protected process.
Monitor processes and command-line arguments for program execution that may be indicative of credential dumping. Remote access tools may contain built-in features or incorporate existing tools like Mimikatz. PowerShell scripts also exist that contain credential dumping functionality, such as PowerSploit's Invoke-Mimikatz module, (Citation: Powersploit) which may require additional logging features to be configured in the operating system to collect necessary information for analysis.
Monitor domain controller logs for replication requests and other unscheduled activity possibly associated with DCSync. (Citation: Microsoft DRSR Dec 2017) (Citation: Microsoft GetNCCChanges) (Citation: Samba DRSUAPI) Note: Domain controllers may not log replication requests originating from the default domain controller account. (Citation: Harmj0y DCSync Sept 2015). Also monitor for network protocols (Citation: Microsoft DRSR Dec 2017) (Citation: Microsoft NRPC Dec 2017) and other replication requests (Citation: Microsoft SAMR) from IPs not associated with known domain controllers.

# T1004 - Winlogon Helper DLL
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1004)
<blockquote>Winlogon.exe is a Windows component responsible for actions at logon/logoff as well as the secure attention sequence (SAS) triggered by Ctrl-Alt-Delete. Registry entries in <code>HKLM\Software\[Wow6432Node\]Microsoft\Windows NT\CurrentVersion\Winlogon\</code> and <code>HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\</code> are used to manage additional helper programs and functionalities that support Winlogon. (Citation: Cylance Reg Persistence Sept 2013)
Malicious modifications to these Registry keys may cause Winlogon to load and execute malicious DLLs and/or executables. Specifically, the following subkeys have been known to be possibly vulnerable to abuse: (Citation: Cylance Reg Persistence Sept 2013)
* Winlogon\Notify - points to notification package DLLs that handle Winlogon events
* Winlogon\Userinit - points to userinit.exe, the user initialization program executed when a user logs on
* Winlogon\Shell - points to explorer.exe, the system shell executed when a user logs on
Adversaries may take advantage of these features to repeatedly execute malicious code and establish Persistence.</blockquote>

Depending on the version of Windows, an adversary may take advantage of these features in different ways because of code integrity enhancements. In newer versions of Windows, the replaced binary needs to be digitally signed for x64 systems, the binary must reside in <code>%systemdir%\</code>, and it must be protected by Windows File or Resource Protection (WFP/WRP). (Citation: DEFCON2016 Sticky Keys) The debugger method was likely discovered as a potential workaround because it does not require the corresponding accessibility feature binary to be replaced. Examples for both methods:
For simple binary replacement on Windows XP and later as well as and Windows Server 2003/R2 and later, for example, the program (e.g., <code>C:\Windows\System32\utilman.exe</code>) may be replaced with "cmd.exe" (or another program that provides backdoor access). Subsequently, pressing the appropriate key combination at the login screen while sitting at the keyboard or when connected over [Remote Desktop Protocol](https://attack.mitre.org/techniques/T1076) will cause the replaced file to be executed with SYSTEM privileges.

(Citation: Tilbury 2014)
For the debugger method on Windows Vista and later as well as Windows Server 2008 and later, for example, a Registry key may be modified that configures "cmd.exe," or another program that provides backdoor access, as a "debugger" for the accessibility program (e.g., "utilman.exe").

Detection: Encryption software and encrypted files can be detected in many ways. Common utilities that may be present on the system or brought in by an adversary may be detectable through process monitoring and monitoring for command-line arguments for known encryption utilities. This may yield a significant amount of benign events, depending on how systems in the environment are typically used. Often the encryption key is stated within command-line invocation of the software.
A process that loads the Windows DLL crypt32.dll may be used to perform encryption, decryption, or verification of file signatures.
Network traffic may also be analyzed for entropy to determine if encrypted data is being transmitted.

# T1027 - Obfuscated Files or Information
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1027)
<blockquote>Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit. This is common behavior that can be used across different platforms and the network to evade defenses.
Payloads may be compressed, archived, or encrypted in order to avoid detection. These payloads may be used during Initial Access or later to mitigate detection. Sometimes a user's action may be required to open and [Deobfuscate/Decode Files or Information](https://attack.mitre.org/techniques/T1140) for [User Execution](https://attack.mitre.org/techniques/T1204). The user may also be required to input a password to open a password protected compressed/encrypted file that was provided by the adversary. (Citation: Volexity PowerDuke November 2016) Adversaries may also used compressed or archived scripts, such as Javascript.
Portions of files can also be encoded to hide the plain-text strings that would otherwise help defenders with discovery. (Citation: Linux/Cdorked.A We Live Security Analysis) Payloads may also be split into separate, seemingly benign files that only reveal malicious functionality when reassembled. (Citation: Carbon Black Obfuscation Sept 2016)
Adversaries may also obfuscate commands executed from payloads or directly via a [Command-Line Interface](https://attack.mitre.org/techniques/T1059). Environment variables, aliases, characters, and other platform/language specific semantics can be used to evade signature based detections and whitelisting mechanisms. (Citation: FireEye Obfuscation June 2017) (Citation: FireEye Revoke-Obfuscation July 2017) (Citation: PaloAlto EncodedCommand March 2017)
Another example of obfuscation is through the use of steganography, a technique of hiding messages or code in images, audio tracks, video clips, or text files. One of the first known and reported adversaries that used steganography activity surrounding [Invoke-PSImage](https://attack.mitre.org/software/S0231). The Duqu malware encrypted the gathered information from a victim's system and hid it into an image followed by exfiltrating the image to a C2 server. (Citation: Wikipedia Duqu) By the end of 2017, an adversary group used [Invoke-PSImage](https://attack.mitre.org/software/S0231) to hide PowerShell commands in an image file (png) and execute the code on a victim's system. In this particular case the PowerShell code downloaded another obfuscated script to gather intelligence from the victim's machine and communicate it back to the adversary.

# T1036 - Masquerading
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1036)
<blockquote>Masquerading occurs when the name or location of an executable, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation. Several different variations of this technique have been observed.
One variant is for an executable to be placed in a commonly trusted directory or given the name of a legitimate, trusted program. Alternatively, the filename given may be a close approximation of legitimate programs. This is done to bypass tools that trust executables by relying on file name or path, as well as to deceive defenders and system administrators into thinking a file is benign by associating the name with something that is thought to be legitimate.
### Windows
In another variation of this technique, an adversary may use a renamed copy of a legitimate utility, such as rundll32.exe. (Citation: Endgame Masquerade Ball) An alternative case occurs when a legitimate utility is moved to a different directory and also renamed to avoid detections based on system utilities executing from non-standard paths. (Citation: F-Secure CozyDuke)
An example of abuse of trusted locations in Windows would be the <code>C:\Windows\System32</code> directory. Examples of trusted binary names that can be given to malicious binares include "explorer.exe" and "svchost.exe".
### Linux
Another variation of this technique includes malicious binaries changing the name of their running process to that of a trusted or benign process, after they have been launched as opposed to before. (Citation: Remaiten)
An example of abuse of trusted locations in Linux would be the <code>/bin</code> directory. Examples of trusted binary names that can be given to malicious binares include "rsyncd" and "dbus-inotifier". (Citation: Fysbis Palo Alto Analysis) (Citation: Fysbis Dr Web Analysis)</blockquote>

## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1037)
<blockquote>### Windows
<blockquote>===Windows===
Windows allows logon scripts to be run whenever a specific user or group of users log into a system. (Citation: TechNet Logon Scripts) The scripts can be used to perform administrative functions, which may often execute other programs or send information to an internal logging server.
If adversaries can access these scripts, they may insert additional code into the logon script to execute their tools when a user logs in. This code can allow them to maintain persistence on a single system, if it is a local script, or to move laterally within a network, if the script is stored on a central server and pushed to many systems. Depending on the access configuration of the logon scripts, either local credentials or an administrator account may be necessary.
### Mac
===Mac===
Mac allows login and logoff hooks to be run as root whenever a specific user logs into or out of a system. A login hook tells Mac OS X to execute a certain script when a user logs in, but unlike startup items, a login hook executes as root (Citation: creating login hook). There can only be one login hook at a time though. If adversaries can access these scripts, they can insert additional code to the script to execute their tools when a user logs in.</blockquote>

Detection: Detecting the events leading up to sniffing network traffic may be the best method of detection. From the host level, an adversary would likely need to perform a man-in-the-middle attack against other devices on a wired network in order to capture traffic that was not to or from the current compromised system. This change in the flow of information is detectable at the enclave network level. Monitor for ARP spoofing and gratuitous ARP broadcasts. Detecting compromised network devices is a bit more challenging. Auditing administrator logins, configuration changes, and device images is required to detect malicious changes.

# T1042 - Change Default File Association
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1042)
<blockquote>When a file is opened, the default program used to open the file (also called the file association or handler) is checked. File association selections are stored in the Windows Registry and can be edited by users, administrators, or programs that have Registry access (Citation: Microsoft Change Default Programs) (Citation: Microsoft File Handlers) or by administrators using the built-in assoc utility. (Citation: Microsoft Assoc Oct 2017) Applications can modify the file association for a given file extension to call an arbitrary program when a file with the given extension is opened.
<blockquote>When a file is opened, the default program used to open the file (also called the file association or handler) is checked. File association selections are stored in the Windows Registry and can be edited by users, administrators, or programs that have Registry access. (Citation: Microsoft Change Default Programs) (Citation: Microsoft File Handlers) Applications can modify the file association for a given file extension to call an arbitrary program when a file with the given extension is opened.
System file associations are listed under <code>HKEY_CLASSES_ROOT\.[extension]</code>, for example <code>HKEY_CLASSES_ROOT\.txt</code>. The entries point to a handler for that extension located at <code>HKEY_CLASSES_ROOT\[handler]</code>. The various commands are then listed as subkeys underneath the shell key at <code>HKEY_CLASSES_ROOT\[handler]\shell\[action]\command</code>. For example:
* <code>HKEY_CLASSES_ROOT\txtfile\shell\open\command</code>
* <code>HKEY_CLASSES_ROOT\txtfile\shell\print\command</code>
* <code>HKEY_CLASSES_ROOT\txtfile\shell\printto\command</code>
*<code>HKEY_CLASSES_ROOT\txtfile\shell\open\command</code>
*<code>HKEY_CLASSES_ROOT\txtfile\shell\print\command</code>
*<code>HKEY_CLASSES_ROOT\txtfile\shell\printto\command</code>
The values of the keys listed are commands that are executed when the handler opens the file extension. Adversaries can modify these values to continually execute arbitrary commands. (Citation: TrendMicro TROJ-FAKEAV OCT 2012)</blockquote>
The values of the keys listed are commands that are executed when the handler opens the file extension. Adversaries can modify these values to execute arbitrary commands.
Detection: Collect and analyze changes to Registry keys that associate file extensions to default applications for execution and correlate with unknown process launch activity or unusual file types for that process.
User file association preferences are stored under <code> [HKEY_CURRENT_USER]\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts</code> and override associations configured under <code>[HKEY_CLASSES_ROOT]</code>. Changes to a user's preference will occur under this entry's subkeys.
Also look for abnormal process call trees for execution of other commands that could relate to Discovery actions or other techniques.

Detection: Monitor scheduled task creation from common utilities using command-line invocation. Legitimate scheduled tasks may be created during installation of new software or through system administration functions. Monitor process execution from the <code>svchost.exe</code> in Windows 10 and the Windows Task Scheduler <code>taskeng.exe</code> for older versions of Windows. (Citation: Twitter Leoloobeek Scheduled Task) If scheduled tasks are not used for persistence, then the adversary is likely to remove the task when the action is complete.

Configure event logging for scheduled task creation and changes by enabling the "Microsoft-Windows-TaskScheduler/Operational" setting within the event logging service. (Citation: TechNet Forum Scheduled Task Operational Setting) Several events will then be logged on scheduled task activity, including: (Citation: TechNet Scheduled Task Events)
*Event ID 106 - Scheduled task registered
*Event ID 140 - Scheduled task updated
*Event ID 141 - Scheduled task removed
Tools such as Sysinternals Autoruns may also be used to detect system changes that could be attempts at persistence, including listing current scheduled tasks.

<blockquote>Process injection is a method of executing arbitrary code in the address space of a separate live process. Running code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via process injection may also evade detection from security products since the execution is masked under a legitimate process.

There are multiple approaches to injecting code into a live process. Windows implementations include: (Citation: Engame Process Injection July 2017)
* '''Dynamic-link library (DLL) injection''' involves writing the path to a malicious DLL inside a process then invoking execution by creating a remote thread.
* '''Portable executable injection''' involves writing malicious code directly into the process (without a file on disk) then invoking execution with either additional code or by creating a remote thread. The displacement of the injected code introduces the additional requirement for functionality to remap memory references. Variations of this method such as reflective DLL injection (writing a self-mapping DLL into a process) and memory module (map DLL when writing into process) overcome the address relocation issue. (Citation: Endgame HuntingNMemory June 2017)
* '''Thread execution hijacking''' involves injecting malicious code or the path to a DLL into a thread of a process. Similar to Process Hollowing, the thread must first be suspended.
* '''Asynchronous Procedure Call''' (APC) injection involves attaching malicious code to the APC Queue (Citation: Microsoft APC) of a process's thread. Queued APC functions are executed when the thread enters an alterable state. AtomBombing (Citation: ENSIL AtomBombing Oct 2016) is a variation that utilizes APCs to invoke malicious code previously written to the global atom table. (Citation: Microsoft Atom Table)
* '''Thread Local Storage''' (TLS) callback injection involves manipulating pointers inside a portable executable (PE) to redirect a process to malicious code before reaching the code's legitimate entry point. (Citation: FireEye TLS Nov 2017)

Detection: Monitoring Windows API calls indicative of the various types of code injection may generate a significant amount of data and may not be directly useful for defense unless collected under specific circumstances for known bad sequences of calls, since benign use of API functions may be common and difficult to distinguish from malicious behavior. API calls such as CreateRemoteThread, SuspendThread/SetThreadContext/ResumeThread, QueueUserAPC, and those that can be used to modify memory within another process, such as WriteProcessMemory, may be used for this technique. (Citation: Engame Process Injection July 2017)
Monitoring for Linux specific calls such as the ptrace system call, the use of LD_PRELOAD environment variable, or dlfcn dynamic linking API calls, should not generate large amounts of data due to their specialized nature, and can be a very effective method to detect some of the common process injection methods. (Citation: ArtOfMemoryForensics) (Citation: GNU Acct) (Citation: RHEL auditd) (Citation: Chokepoint preload rootkits)
Monitor for named pipe creation and connection events (Event IDs 17 and 18) for possible indicators of infected processes with external modules. (Citation: Microsoft Sysmon v6 May 2017)
Monitor processes and command-line arguments for actions that could be done before or after code injection has occurred and correlate the information with related event information. Code injection may also be performed using PowerShell with tools such as PowerSploit, (Citation: Powersploit) so additional PowerShell monitoring may be required to cover known implementations of this behavior.

# T1056 - Input Capture
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1056)
<blockquote>Adversaries can use methods of capturing user input for obtaining credentials for [Valid Accounts](https://attack.mitre.org/techniques/T1078) and information Collection that include keylogging and user input field interception.
<blockquote>Adversaries can use methods of capturing user input for obtaining credentials for Valid Accounts and information Collection that include keylogging and user input field interception.
Keylogging is the most prevalent type of input capture, with many different ways of intercepting keystrokes, (Citation: Adventures of a Keystroke) but other methods exist to target information for specific purposes, such as performing a UAC prompt or wrapping the Windows default credential provider. (Citation: Wrightson 2012)
Keylogging is likely to be used to acquire credentials for new access opportunities when [Credential Dumping](https://attack.mitre.org/techniques/T1003) efforts are not effective, and may require an adversary to remain passive on a system for a period of time before an opportunity arises.
Keylogging is likely to be used to acquire credentials for new access opportunities when Credential Dumping efforts are not effective, and may require an adversary to remain passive on a system for a period of time before an opportunity arises.
Adversaries may also install code on externally facing portals, such as a VPN login page, to capture and transmit credentials of users who attempt to log into the service. This variation on input capture may be conducted post-compromise using legitimate administrative access as a backup measure to maintain network access through [External Remote Services](https://attack.mitre.org/techniques/T1133) and [Valid Accounts](https://attack.mitre.org/techniques/T1078) or as part of the initial compromise by exploitation of the externally facing web service. (Citation: Volexity Virtual Private Keylogging)</blockquote>

(Citation: Volexity Virtual Private Keylogging)
Detection: Keyloggers may take many forms, possibly involving modification to the Registry and installation of a driver, setting a hook, or polling to intercept keystrokes. Commonly used API calls include SetWindowsHook, GetKeyState, and GetAsynceyState. (Citation: Adventures of a Keystroke) Monitor the Registry and file system for such changes and detect driver installs, as well as looking for common keylogging API calls. API calls alone are not an indicator of keylogging, but may provide behavioral data that is useful when combined with other information such as new files written to disk and unusual processes.
Monitor the Registry for the addition of a Custom Credential Provider. (Citation: Wrightson 2012) Detection of compromised Valid Accounts in use by adversaries may help to catch the result of user input interception if new techniques are used.

# T1060 - Registry Run Keys / Startup Folder
# T1060 - Registry Run Keys / Start Folder
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1060)
<blockquote>Adding an entry to the "run keys" in the Registry or startup folder will cause the program referenced to be executed when a user logs in. (Citation: Microsoft Run Key) These programs will be executed under the context of the user and will have the account's associated permissions level.
<blockquote>Adding an entry to the "run keys" in the Registry or startup folder will cause the program referenced to be executed when a user logs in. (Citation: Microsoft Run Key) The program will be executed under the context of the user and will have the account's associated permissions level.
The following run keys are created by default on Windows systems:
* <code>HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run</code>
* <code>HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce</code>
* <code>HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run</code>
* <code>HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce</code>
Adversaries can use these configuration locations to execute malware, such as remote access tools, to maintain persistence through system reboots. Adversaries may also use Masquerading to make the Registry entries look as if they are associated with legitimate programs.
The <code>HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnceEx</code> is also available but is not created by default on Windows Visa and newer. Registry run key entries can reference programs directly or list them as a dependency. (Citation: Microsoft RunOnceEx APR 2018) For example, it is possible to load a DLL at logon using a "Depend" key with RunOnceEx: <code>reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx\0001\Depend /v 1 /d "C:\temp\evil[.]dll"</code> (Citation: Oddvar Moe RunOnceEx Mar 2018)
Detection: Monitor Registry for changes to run keys that do not correlate with known software, patch cycles, etc. Monitor the start folder for additions or changes. Tools such as Sysinternals Autoruns may also be used to detect system changes that could be attempts at persistence, including listing the run keys' Registry locations and startup folders. (Citation: TechNet Autoruns) Suspicious program execution as startup programs may show up as outlier processes that have not been seen before when compared against historical data.
The following Registry keys can be used to set startup folder items for persistence:
* <code>HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders</code>
* <code>HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders</code>
* <code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders</code>
* <code>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders</code>
Changes to these locations typically happen under normal conditions when legitimate software is installed. To increase confidence of malicious activity, data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities, such as network connections made for Command and Control, learning details about the environment through Discovery, and Lateral Movement.
Adversaries can use these configuration locations to execute malware, such as remote access tools, to maintain persistence through system reboots. Adversaries may also use [Masquerading](https://attack.mitre.org/techniques/T1036) to make the Registry entries look as if they are associated with legitimate programs.</blockquote>

# T1064 - Scripting
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1064)
<blockquote>Adversaries may use scripts to aid in operations and perform multiple actions that would otherwise be manual. Scripting is useful for speeding up operational tasks and reducing the time required to gain access to critical resources. Some scripting languages may be used to bypass process monitoring mechanisms by directly interacting with the operating system at an API level instead of calling other programs. Common scripting languages for Windows include VBScript and PowerShell but could also be in the form of command-line batch scripts.
Scripts can be embedded inside Office documents as macros that can be set to execute when files used in [Spearphishing Attachment](https://attack.mitre.org/techniques/T1193) and other types of spearphishing are opened. Malicious embedded macros are an alternative means of execution than software exploitation through [Exploitation for Client Execution](https://attack.mitre.org/techniques/T1203), where adversaries will rely on macos being allowed or that the user will accept to activate them.
Many popular offensive frameworks exist which use forms of scripting for security testers and adversaries alike. (Citation: Metasploit) (Citation: Metasploit), (Citation: Veil) (Citation: Veil), and PowerSploit (Citation: Powersploit) are three examples that are popular among penetration testers for exploit and post-compromise operations and include many features for evading defenses. Some adversaries are known to use PowerShell. (Citation: Alperovitch 2014)</blockquote>

# T1070 - Indicator Removal on Host
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1070)
<blockquote>Adversaries may delete or alter generated artifacts on a host system, including logs and potentially captured files such as quarantined malware. Locations and format of logs will vary, but typical organic system logs are captured as Windows events or Linux/macOS files such as [Bash History](https://attack.mitre.org/techniques/T1139) and /var/log/* .
<blockquote>Adversaries may delete or alter generated event files on a host system, including potentially captured files such as quarantined malware. This may compromise the integrity of the security solution, causing events to go unreported, or make forensic analysis and incident response more difficult due to lack of sufficient data to determine what occurred.
Actions that interfere with eventing and other notifications that can be used to detect intrusion activity may compromise the integrity of security solutions, causing events to go unreported. They may also make forensic analysis and incident response more difficult due to lack of sufficient data to determine what occurred.
Detection: File system monitoring may be used to detect improper deletion or modification of indicator files. Events not stored on the file system will require different detection mechanisms.
### Clear Windows Event Logs
Platforms: Linux, macOS, Windows
Windows event logs are a record of a computer's alerts and notifications. Microsoft defines an event as "any significant occurrence in the system or in a program that requires users to be notified or an entry added to a log." There are three system-defined sources of Events: System, Application, and Security.
Adversaries performing actions related to account management, account logon and directory service access, etc. may choose to clear the events in order to hide their activities.
Data Sources: File monitoring, Process command-line parameters, Process monitoring
The event logs can be cleared with the following utility commands:
* <code>wevtutil cl system</code>
* <code>wevtutil cl application</code>
* <code>wevtutil cl security</code>
Logs may also be cleared through other mechanisms, such as [PowerShell](https://attack.mitre.org/techniques/T1086).</blockquote>

<blockquote>Pass the hash (PtH) is a method of authenticating as a user without having access to the user's cleartext password. This method bypasses standard authentication steps that require a cleartext password, moving directly into the portion of the authentication that uses the password hash. In this technique, valid password hashes for the account being used are captured using a Credential Access technique. Captured hashes are used with PtH to authenticate as that user. Once authenticated, PtH may be used to perform actions on local or remote systems.

# T1076 - Remote Desktop Protocol
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1076)
<blockquote>Remote desktop is a common feature in operating systems. It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS). (Citation: TechNet Remote Desktop Services) There are other implementations and third-party tools that provide graphical access [Remote Services](https://attack.mitre.org/techniques/T1021) similar to RDS.

(Citation: TechNet Remote Desktop Services) There are other implementations and third-party tools that provide graphical access Remote Services similar to RDS.
Adversaries may connect to a remote system over RDP/RDS to expand access if the service is enabled and allows access to accounts with known credentials. Adversaries will likely use Credential Access techniques to acquire credentials to use with RDP. Adversaries may also use RDP in conjunction with the [Accessibility Features](https://attack.mitre.org/techniques/T1015) technique for Persistence. (Citation: Alperovitch Malware)

Adversaries will likely use Credential Access techniques to acquire credentials to use with RDP. Adversaries may also use RDP in conjunction with the Accessibility Features technique for Persistence. (Citation: Alperovitch Malware)
Adversaries may also perform RDP session hijacking which involves stealing a legitimate user's remote session. Typically, a user is notified when someone else is trying to steal their session and prompted with a question. With System permissions and using Terminal Services Console, <code>c:\windows\system32\tscon.exe [session number to be stolen]</code>, an adversary can hijack a session without the need for credentials or prompts to the user. (Citation: RDP Hijacking Korznikov) This can be done remotely or locally and with active or disconnected sessions. (Citation: RDP Hijacking Medium) It can also lead to [Remote System Discovery](https://attack.mitre.org/techniques/T1018) and Privilege Escalation by stealing a Domain Admin or higher privileged account session. All of this can be done by using native Windows commands, but it has also been added as a feature in RedSnarf. (Citation: Kali Redsnarf)</blockquote>

Detection: Use of RDP may be legitimate, depending on the network environment and how it is used. Other factors, such as access patterns and activity that occurs after a remote login, may indicate suspicious or malicious behavior with RDP. Monitor for user accounts logged into systems they would not normally access or access patterns to multiple systems over a relatively short period of time.
Also, set up process monitoring for <code>tscon.exe</code> usage and monitor service creation that uses <code>cmd.exe /k</code> or <code>cmd.exe /c</code> in its arguments to prevent RDP session hijacking.

Detection: Use process monitoring to monitor the execution and arguments of rundll32.exe. Compare recent invocations of rundll32.exe with prior history of known good arguments and loaded DLLs to determine anomalous and potentially adversarial activity. Command arguments used with the rundll32.exe invocation may also be useful in determining the origin and purpose of the DLL being loaded.

Detection: If proper execution policy is set, adversaries will likely be able to define their own execution policy if they obtain administrator or system access, either through the Registry or at the command line. This change in policy on a system may be a way to detect malicious use of PowerShell. If PowerShell is not used in an environment, then simply looking for PowerShell execution may detect malicious activity.
It is also beneficial to turn on PowerShell logging to gain increased fidelity in what occurs during execution. (Citation: Malware Archaeology PowerShell Cheat Sheet) PowerShell 5.0 introduced enhanced logging capabilities, and some of those features have since been added to PowerShell 4.0. Earlier versions of PowerShell do not have many logging features.

# T1088 - Bypass User Account Control
## [Description from ATT&CK](https://attack.mitre.org/wiki/Technique/T1088)
<blockquote>Windows User Account Control (UAC) allows a program to elevate its privileges to perform a task under administrator-level permissions by prompting the user for confirmation. The impact to the user ranges from denying the operation under high enforcement to allowing the user to perform the action if they are in the local administrators group and click through the prompt or allowing them to enter an administrator password to complete the action. (Citation: TechNet How UAC Works)
If the UAC protection level of a computer is set to anything but the highest level, certain Windows programs are allowed to elevate privileges or execute some elevated COM objects without prompting the user through the UAC notification box. (Citation: TechNet Inside UAC) (Citation: MSDN COM Elevation) An example of this is use of rundll32.exe to load a specifically crafted DLL which loads an auto-elevated COM object and performs a file operation in a protected directory which would typically require elevated access. Malicious software may also be injected into a trusted process to gain elevated privileges without prompting a user. (Citation: Davidson Windows) Adversaries can use these techniques to elevate privileges to administrator if the target process is unprotected.
Many methods have been discovered to bypass UAC. The Github readme page for UACMe contains an extensive list of methods (Citation: Github UACMe) that have been discovered and implemented within UACMe, but may not be a comprehensive list of bypasses. Additional bypass methods are regularly discovered and some used in the wild, such as:
* <code>eventvwr.exe</code> can auto-elevate and execute a specified binary or script. (Citation: enigma0x3 Fileless UAC Bypass) (Citation: Fortinet Fareit)
Another bypass is possible through some Lateral Movement techniques if credentials for an account with administrator privileges are known, since UAC is a single system security mechanism, and the privilege or integrity of a process running on one system will be unknown on lateral systems and default to high integrity. (Citation: SANS UAC Bypass)</blockquote>
