Free security tool detects banking malware

Security company Fitsec says its free DeBank tool nearly always spots variants of SpyEye, Zeus and other nasty malware

A Finnish penetration testing company has released a free tool it says can detect all variants of five major families of malicious software that steal online banking credentials.

The tool, called Debank, was built by Finnish penetration testing company Fitsec, which has used the tool to scan its customers' machines, said company founder Toni Koivunen.

The tool works by scanning a computer's process memory, Koivunen said. Most malicious software these days is "packed," or compressed, before it is distributed. That can fool antivirus programs, since the malware can appear to be a different program each time it is repacked.

Koivunen said antivirus programs often use heuristics as an alternative way to detect malware aside from traditional signatures, but that method is not always as successful as a full memory sweep.

Debank looks at the program after it has been executed on a computer. Malware authors rarely change the core code of the program, which is what Debank analyzes.

Koivunen said Debank can detect nearly all variants of SpyEye, Zeus, CarBerp, Gozi and Patcher, five well-known banking malware programs. The malware has to be running for Debank to detect it and the tool only works on computers running Windows, he said.

Debank was able to detect more than 200 variants of Patcher after FitSec found a part of its code common to all variants. FitSec has also tested it against hundreds of variants of SpyEye, a particularly advanced piece of code that operates as part of a botnet. It can harvest credentials for online accounts and also initiate transactions even while a person is logged into their account.

Fitsec decided to just give the tool away and has made it available for download on their blog. "We had no reason to start charging for it," Koivunen said. "Basically, we hate malware."

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
