RageLtMan 3778ae09e9 This commit adds DNS resolution to rev_tcp_rc4 
Due to the modular structure of payload stages its pretty trivial
to add DNS resolution instead of hard-coded IP address in stage0.

The only real complication here is that ReverseConnectRetries ends
up being one byte further down than in the original shellcode. It
appears that the original rev_tcp_dns payload suffers from the same
issue.

Hostname substitution is handled in the same method as the RC4 and
XOR keys, with an offset provided and replace_vars ignoring the
hostname.

Tested in x86 native and WOW64 on XP and 2k8r2 respectively.

This is a good option for those of us needing to leave persistent
binaries/payloads on hosts for long periods. Even if the hostname
resolves to a malicious party attempting to steal our hard earned
session, they'd be hard pressed to crypt the payload with the
appropriate RC4 pass. So long as we control the NS and records, the
hardenned shellcode should provide a better night's sleep if running
shells over the WAN. Changing the RC4 password string in the
shellcode and build.py should reduce the chances of recovery by RE.

Next step will likely be to start generating elipses for ECDH SSL
in meterpreter sessions and passing them with stage2 through the
RC4 socket. If P is 768-1024 the process is relatively quick, but
we may want to precompute a few defaults as well to have 2048+.

Michael Schierl 46a5c4f4bf Improve RC4 shellcode 
ESI is not clobbered; no need to clear EDX as only DL is filled before and
it is overwritten before use.

Shellcodes in ruby modules not regenerated, but I guess you want to
regenerate them again anyway :-)

Michael Schierl cb06262002 Add shellcode for RC4 bind and reverse stagers 
Those stagers will encrypt the initial stage with a 128-bit RC4 key and
the stage length with a XOR key. Both keys are embedded in the stager.

This should provide good evasion capabilities in addition to some
protection against MITM reversing (if the stager is sent a different
route, like in an executable on an USB key).

Note that, from a cryptanalyst's standpoint, it is a bad idea to reuse the
same stager (or stagers with the same RC4 and XOR keys) more than once
since an identical key will result in an identical keystream and make
correlation attacks easy. But I doubt that matters in practice.

Also note that since communication after the initial statging is not
encrypted, these stagers should be used in combination with additional
encryption support in the payloads (like Meterpreter).

Michael Schierl b4fd341fb6 Add shellcode for RC4 decoding 
Provided as a block to be included into stagers and/or decoder stubs.
Also included is a test shellcode that can be used for verifying that the
algorithm is compatible to Ruby's OpenSSL RC4 algorithm.

James Lee f38ac954b8 Update linux stagers for NX compatibility 
- Adds a call to mprotect(2) to the reverse and bind stagers

- Adds accurate source for some other linux shellcode, including some
  comments to make it more maintainable

- Adds tools/module_payload.rb for listing all payloads for each exploit
  in a greppable format. Makes it easy to find out if a payload change
  causes a payload to no longer be compatible with a given exploit.

- Missing from this commit is source for reverse_ipv6_tcp

James Lee 7afd470eb0 Clean up linux shellcode Makefile 
Now you can "make single_bind_tcp_shell", or the like, and build one
payload instead of the kludgy embedded shell script that always builds
all of them.

Need to do the same with BSD.

Stephen Fewer c55e9af9ae Commit the updated APC injection stubs. fixes a nasty issue in some edge cases whereby when using APC injection for a process in another session then the current host process the injected APC can cause an access violation in kernel32 during a call the kernel32!CreateThread caused by the APC's host thread not having an initialized Activation Context inside its TEB. We now test for this and create a dummy ActivationContext entry to appease the kernel. This will both improve DLL injection reliability as well as meterpreter migration reliability.

HD Moore ee9a8f4f76 Adds support for the reverse_tcp_allports stager for Windows. This payload tries to connect back on all ports, one at a time, from LPORT to 65535. This is incredibly slow (depends on the default socket timeout) and requires the user to forward all TCP ports of LHOST to a single listening port in the handler.
