Sophos Genotype technology proactively protects against MyDoom-BN worm

Sophos products include Genotype technology to proactively defend against new threats
Genotype technology is built into all Sophos products, proactively defending against new threats.

Experts at SophosLabs™, Sophos's global network of virus and spam analysis centres, have successfully defended customers against a new version of the MyDoom worm this week, using proactive technology.

A virus author unleashed the latest version of the MyDoom worm, W32/MyDoom-BN, earlier this week. Sophos's proactive Genotype™ technology was capable of detecting it proactively (naming it as W32/MyDoom-Gen), defending customers' computers without requiring an update.

The MyDoom-BN worm spreads via email, planting a backdoor Trojan horse which can be used by remote hackers to gain access and control over a victim's computer.

Genotype™ detection technology uses forensic analysis to identify suspicious patterns and characteristics that are unique to either a virus family or a spam campaign. By analyzing these Genotype patterns, Sophos reduces exposure to new unidentified threats and unwanted content.

"With hundreds of new virus threats emerging each month all businesses want to have the very latest protection. Sophos's unique and proactive Genotype technology helps protect businesses worldwide against new attacks - even before they have been seen by anti-virus experts," said Graham Cluley, senior technology consultant for Sophos. "The security of companies is boosted by combining traditional anti-virus protection with proactive Genotype detection. Additionally, businesses should put an email security policy in place at their gateways. Millions of Sophos customers are already benefiting from this high level of proactive protection."

Sophos's Genotype technology also successfully proactively protected customers against a multitude of new versions of the Mytob worm earlier this month.
