Hiding in plain sight: a story about a sneaky banking Trojan

Quote:
The Zeus/Zbot Trojan is one the most notorious banking Trojans ever created; it’s so popular it gave birth to many offshoots and copycats.

The particularity of Zeus is that it acts as a “man-in-the-browser“ allowing cyber-crooks to collect personal information from its victims as well as to surreptitiously perform online transactions.

A new variant of this trojan, dubbed ZeusVM, is using images as a decoy to retrieve its configuration file, a vital piece for its proper operation.

French security researcher Xylitol noted something strange in one of the malvertising campaigns I reported a couple weeks ago.

The malware was retrieving a JPG image hosted on the same server as were other malware components.

He later sent me a message about how this new variant was using steganography, a technique that allows to disguise data inside of an existing file without damaging it.

I have had a problem in the past trying to explain to some that pictures can infect you computer.
They should be scanned like any other thing you get from the web.
