Technical paper - Fake anti-virus: The journey from Trojan to a persistent threat

Filed Under: Malware, SophosLabs

Fake stamp, courtesy of ShutterstockFake anti-virus (also known as scareware) has grown over the years into a persistent and prevalent threat and is now one of the largest families of malware that we've seen in recent history.

In this new technical paper from SophosLabs, threat researcher Jagadeesh Chandraiah studies the evolution of fake anti-virus over the last three and a half years.

He looks at the major fake anti-virus events, infection vectors and some important anti-emulation/anti-reverse engineering (RE) tricks used by fake anti-virus packers.

He also analyses how exploit kits are used to infect users with fake anti-virus and studies how a polymorphic packer found in underground internet forums is used to encrypt and compress the malware binary.

    Very good read and good detail into the process of this, this seems to be a ever expanding trend.

    I would like to know what methods the criminals use to retrieve the money of there victims do they use a rogue credit card payment taker? wester union or some other kind of service.

    It amazes me how little awarness there is is about this kind of threat.

    Cheers
