Subject: Re: RAR Cracking with JtR Jumbo (Files found during forensics)

Hello Nicolas
I had little expirience with trojans encrypted with so called FUD, as far
as i've seen passowrds for encrypted installation/updateds were
stored in plain text file next to archive. Passwords however were very
complex. I know it's long shot but if You still can access infected
machine, it might be worth to check for those text files...

best regards
Bartosz
