New "CryptoLocker" samples; bypass CryptoPrevent?

Postby SimonZerafa » Tue Mar 04, 2014 6:05 am

Hi Nick,

Two new samples of CryptoLocker (or something that calls itself that and does a similar job) here: ... ...

[ Password for both is "infected" sans quotes - Take care when downloading or examining! :-) ]

These two samples are reported to bypass CryptoPrevent by running from the "Start Up" folders for ALL users (including SYSTEM level ones).

Not verified this myself as yet; will try to run these in a contained environment as soon as I can.

Thought you might like to take a look and see if you can update CryptoPrevent to work around this new version (if possible).

Kind Regards

thanks Simon! The last one I had was from Feb 10th. I will check these out ASAP.

Moved to Malware Exchange forum where malware samples should be shared. My fault for not posting a rule or anything, but I want to keep malware samples posted to this forum only which is not indexed by bots and the like, to keep some security 'features' from flagging the forums as potentially malicious.
