Trojans total half of BitDefender’s top 10 e-threats for June

July 2009 Information Security

Conficker’s domination is dwindling, while Trojan.Clicker.CM heads the pack by bypassing popup blockers.

BitDefender, an award-winning provider of innovative anti-malware security solutions, has released the top 10 e-threats for the month of June, and Trojans continue to dominate the list.  Five of the 10 worst e-threats are Trojans, making this the best represented e-threat category.

In tenth position is a generic detection for e-threats packed with NSAnti, a very popular program used by virus writers to obfuscate the contents of their infected files and reduce their size in transit.

Ninth position is held by NaviPromo, an old adware downloader that found a new lease of life. NaviPromo is the 'dark half' of the infamous Navi toolbar.

In eighth position, Trojan.Autorun.AET used what has undoubtedly become 'vulnerability of the year', the Autorun bug in Windows, to carve itself 2,08% of the total number of infected machines.

The only new e-threat in this month's list is Trojan.Skintrim.HTML.A, which poses as an Outlook add-in called MailSkinner. The Trojan is in fact a rootkit/backdoor combination attempting to download and install additional malware on infected machines.

Win32.Sality.OG, a rootkit-installing file infector, jumps up three positions from the BitDefender’s May top 10 e-threats list, moving into sixth place. Ranked fifth is Downadup.Gen, also known as Conficker or Kido. This e-threat is on a slight decrease, totaling 3,33% of total e-threats in June as opposed to last month's 4,35%.

A SWF exploit that is heavily used in the wild landed in fourth place. Although old, it probably owes its position to the large number of different viruses which still include it in their 'armoury'.

Trojan.Wimad, in its various guises, occupies third spot. This is an unexpected comeback from a worm which did not rank last month.

In second place is Trojan.AutorunINF.Gen, which stands for a very widespread 'family' of malware which uses the Autorun file on shared folders and removable drives to spread. This e-threat is also on a slight increase as compared to last month, but it has been 'de-throned' from the first position by Trojan.Clicker.CM, a simple bit of adware being spread via malicious websites. Clicker is one of the most common threats of the year, owing its 'success' to its ability to bypass popup blockers.

BitDefender’s June 2009 Top 10 E-Threat list includes:

1. Trojan.Clicker.CM: 10,13%

2. Trojan.AutorunINF.Gen: 10,04%

3. Trojan.Wimad.Gen.:1 5,6%

4. Exploit.SWF.Gen: 4,34%

5. Win32.Worm.Downadup.Gen: 3,33%

6. Win32.Sality.OG: 2,5%

7. Trojan.Skintrim.HTML.A: 2,37%

8. Trojan.Autorun.AET 2,08%

9. Adware.Downloader.NaviPromo.B: 1,59%

10. Packer.Malware.NSAnti.:1,59%

Other malware: 56,18%
