Technical Details

At the moment, there are four different versions of MutaGen in distribution. Each successive version is more complex than the previous ones. Their sizes range from 1032 bytes to 1385 bytes. In MutaGen's documentation, MnemoniX criticizes the other polymorphic generators for being too unreliable and easy to detect.

MnemoniX himself has published two different viruses which utilise the MutaGen generator, but otherwise the response of the virus underground to this new generator is unknown.
