NOD32 Antivirus Software Customers Protected Without Relying on Signatures

2nd March 2005 – Eset, a global security software solutions company providing next-generation virus protection, today announced that the company’s advanced heuristics detected several thousand messages carrying variants of the Trojan based on the Bagle worms. Eset has identified the initial variants as the Bagle.BA and Bagle.BB Trojan.

The Bagle viruses, which created havoc on email systems for much of last year, are clearly still causing damage. Today’s spam runs containing various Trojan components were most likely sent out via the so called “zombie” networks that Bagle created. These networks are created by the Trojan components in some common email worms such as the Bagle and Netsky families which lurk on infected machines usually without the awareness of the owner. The networks are then used by spammers and other criminals to send out messages or commit identity fraud.

Eset’s virus-radar—a real time malware tracking tool ( picked up this morning’s run. Using the advanced heuristic capabilities of Eset’s NOD32 antivirus system, virus-radar was able to detect all the variants of the Trojans and protect Eset’s customers without the need for updates.

In the initial outbreak, it was thought by many that the huge spam run contained variants of Bagle worms but this proved not to be so. The Trojans were actually attempting to download various other components—some of which may have been intended to add mass mailing capabilities to the Trojans. An infected machine is unable to update its antivirus program, as the Trojan overwrites the host file that Microsoft™ Windows™ uses to manually override DNS names.

Those who are now frequently exploiting the capabilities of malware to further their criminal aims are well aware of the potential that zombie networks offer in terms of reducing their costs and how difficult such attacks are to prevent with conventional technologies, and are actively seeking to expand the networks of such compromised machines.

Proactive technology such as Eset’s advanced heuristics are a vital weapon in the fight against such malicious attacks, and as spam runs are typically short, ephemeral runs of messages which will not be repeated exactly, the traditional model of waiting for an update to detect the malware is useless.
