Re: Lethic proxy

[Nikhil Wagholikar <visitnikhil () gmail com>]

Hello Garfield,

Lethic is known to have varied generic names and doesn't have a common
behaviour pattern. However from the samples those were studied by
researcher, gave a fair clue about this spambot.

One of the features of Lethic is that it injects itself in
Explorer.exe and creates a random-named mutex in the infected machine.
This can be verified using tool 'Process Explorer' from 'Sysinternals
suite'.

More Info about Lethic:

Hope this helps!
