BitDefender September Top Ten
A Flatter Curve

There can be little doubt now that the age of big, flashy, world-arresting malware epidemics is all but over. This month's top ten threats, according to BitDefender Labs, make up 64 percent of all malware detected, yet the peer-to-peer worm Puce.G accounts for only
11.1 of total detections, a far cry from the times when Sasser or Blaster accounted for 60 - 80 percent of a month's malware all by themselves.

Notable threats of the month include the Solow worm, a throwback to the ancient days of virus writing, which simply copies itself to every drive that it can find, adding itself as an autorun entry, so it gets executed when the disc is first accessed.

Another new entry is Ice.a worm, a complex worm sporting a file-infector component and a downloader which downloads and executes a file from a given URL (the url seems to have been inactivated) http://www.bitdefender.com/VIRUS-1000189-en--Win32.Worm.Ice.A.html

Finally, the most virulent new threat sits at #3 and spreads by means of creating copies of itself along with autorun.inf files pointing to them in each and every drive it can find. Once installed, this worm also attempts to disable various kinds of security software and to download and run yet another piece of malware (fortunately, the download location has now been brought offline).

Meanwhile, last month's most important new threat, the Kobcka trojan, seems to have not had as great an impact as feared and failed to make it into the top ten.

"Malware writers seem to have found out that discretion is the better part of valor and are striving to produce stealthy custom viruses that will do what's required of them and no more, to avoid early detection by antivirus companies" declared Head of Antivirus Lab Viorel Canja for BitDefender.
