Alpha2 Alphanumeric Mixedcase Encoder

Created
05/30/2018

Description

Encodes payloads as alphanumeric mixedcase text. This encoder uses SkyLined's Alpha2 encoding suite. A pure alpha encoder is impossible without having a register that points at or near the shellcode. In a default configuration the first few bytes at the beginning are an fnstenv getpc stub (the same as used in shikata_ga_nai) and thus are not alphanumeric. You can set BufferRegister for full alpha (see Encoder options for details).

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
