MutaGen-based viruses

Description MutaGen-based viruses

MutaGen (MGen) is a polymorphic generator, like the MtE or TPE generators. It creates the decryption routine and encrypts the virus body, then the virus saves these part of code in file on infection.
There are several different MutaGen versions, they contain the internal text strings:
"MutaGen.090": [MutaGen .90ß] MnemoniX
"MutaGen.095": [MutaGen .95ß] MnemoniX
"MutaGen.100": [MutaGen 1.00] MnemoniX
"MutaGen.110": [MutaGen 1.1]MnemoniX
"MutaGen.12": [MutaGen 1.2] MnemoniX
"MutaGen.20": [MutaGen 2.0] MnemoniX

MutaGen.Agent
These viruses are included in distribution of MUTAGEN generator. Some of them are not memory resident, other stay resident in memory and hook INT 21h. These viruses write themselves at the end of COM-files. They contain one of the strings:
[MutaGenic Agent]
[MutaGenic Agent I]
[MutaGenic Agent II]
MutaGenic Agent ]I[

MutaGen.100.Garden
It's a dangerous not memory resident overwriting virus. It searches for three .COM- and .EXE-files of current directory and overwrites them. It displays the messages:
Not enough memory.
I need 4K more to start myself!
FUCK PEARL JAM!!!!LONG LIVE TECHNO!!!!

It also contains the internal string:
[Garden]This is Garden V1.0.Very simple virus.New version will be better!!!

MutaGen.100.Secret
It's a dangerous not memory resident parasitic virus. It searches for COM-files of current directory and writes itself at their end. On 11th of any month it corrupts COMMAND.COM, displays the messages and reboots computer:
I AM GOING TO FUCK YOUR HARD DISK IF YOU DON'T TYPE THE RIGHT PASSWORD.
DON'T TURN OFF YOUR COMPUTER BECAUSE I ALREADY FUCKED YOUR HARD DISK
AND I WILL FIX IT ONLY IF YOU ENTER THE RIGHT PASSWORD!!!

FUCK YOU!!! HA HA HA HA!!!

It also contains the internal strings:

MutaGen.110.CF.2055
It's a harmless memory resident parasitic virus. It hooks INT 21h and writes itself at the end of COM- and EXE-files that are executed or opened. It contains the internal text string:
[BW] [Cf-252] MnemoniX Californium-252

MutaGen.110.HiTek.2193
It's a harmless not memory resident parasitic virus. It searches for .COM- and .EXE-files and writes itself at their ends. It contains internal string: "[BW ß] [Hi Tek] by MnemoniX".
