Web threats

Several potentially dangerous WMV (video files) are currently floating around P2P networks. We are detecting them as Trojan-Downloader.WMA.Wimad.a and Trojan-Downloader.WMA.Wimad.b.

We have detected a new Santy variant which also targets vulnerabilties in older versions of php. This new variant is more advanced/dangerous in a number of ways.

New variant of Santy was found some hours ago. We detect it as Net-Worm.Perl.Santy.b.

We’ve intercepted a few samples of a new Mydoom variant this morning. Detection has been made available with the latest antivirus database update as “Email-Worm.Win32.Mydoom.ad”.

A new variant in the Zafi family started to spread earlier today and seems to be propagating pretty fast.

Saturday seemed like a quiet day, apart from the new Sober, however it was far from that. In the morning I received some local reports claiming that some respectable sites were distributing malware.

A new variant of Bofra has been reported – we are trying to get the distribution site closed.
