BitDefender Presents Top Malware Chart for May

File infectors were the main threats facing web users all through May 2007, according to new research. BCS News published this as news on June 1, 2007.

Software firm BitDefender Labs revealed that bulk e-mailed viruses subsided in May this year, while file infectors like Puce.G and Jeefo.A were in the top ten replacing traditional viruses.

The Puce.G worm was in the first position in May malware charts. It is a worm that scatters via P2P file sharing programs. On the other hand, Jeefo.A is authored in MinGW, which is capable of damaging files beyond repair. The Puce.E worm, which occupied the fifth position, similarly spreads via peer-to-peer networks. Next was the new Dowloader.NZR Trojan, written to download additional malware onto an affected system.

The other bothering new entry in the top malware list of BitDefender was the Jeefo.A file infector. It is a most common virus authored in MinGW and uses encrypting technologies. The virus is quite dangerous, as the files it attacks cannot be repaired.

As mass mailers seem to virtually disappear from the top malwares, there is somewhat a diminishing trend for consolidation, noted Viorel Canja, head of BitDefender Labs. Home.businesswire published Canja's comment in a press release on June 1, 2007.

BitDefender's Top 10-malware list for May 2007 consisted of win32.worm.p2p.puce.g -10.31% Win32.worm.rjump.b -7.80%, win32.worm.agent.ai -5.76%, win32.worm.vb.ymeak.a -4.10%, win32.jeefo.a -4.04%, win32.fidcop.gen -3.85%, win32.netsky.p@mm -3.82%, worm.vbs.solow.a -3.45%, win32.wukill.e@mm -2.91% and win32.worm.vb.dw -2.14%.

BitDefender's Top 10-malware list for April consisted of Win32.Worm.Mytob.GZ- 32.07%, Win32.Zafi.B@mm- 10.29%, Win32.Netsky.P@mm- 8.27%, Trojan.Peed.Gen- 8.02%, Win32.Bagle.GM@mm- 6.67%, BehavesLike:Trojan.Downloader- 3.80%, Win32.Nyxem.E@mm- 1.46%, Win32.Worm.Stration.FC.m- 1.37%, Win32.NetSky.D@mm- 0.89%, Win32.NetSky.AA@mm- 0.76%. The remaining malware estimated to be 26.39%.

While these estimates were being readied, Canja noted in the first week of April this year that consolidation in variants of viruses would tend to continue on the Web. The month of May had a major 60 percent of total viruses in the top ten list. Canja further said that the Internet version of natural selection might become active where a handful of successful viruses would displace the not so successful ones in huge amounts.
