Sophos has reported that online security threats have increased by 48% in 2005. Sophos has identified 15,907 new malware threats in 2005.

The Sophos Security Threat Management Report 2005 has reported that one in every 44 emails in 2005 was found to contain some kind of virus or malware.

The Top 10 malware reported were:

Zafi-D
Netsky-P
Sober-Z
Sober-N
Zafi-B
Mytob-BE
Mytob-AE
Mytob-AS
Netsky-D
Mytob-GH and
Mytob-EP.

Zafi-D was the hightest threat with 16.7% of reports. Netsky-P was the next highest with 15.7%.

Graham Cluley, senior technology consultant, Sophos, said, “This huge increase stems from the escalating interest in authoring Trojans, worms and viruses shown by criminal gangs intent on making a profit.

By focusing their efforts on a smaller number of victims, cybercriminals can target them with bespoke malware, increasing their chances of slipping under the security net.” [Source]

Even though the top 10 security threats were worms, the number of Trojan horses written in 2005 outweighed the number of worms by a ratio of 2:1.

The percentage of malware, including spyware, increased from 54.2% in January to 66.5% in December. The report also revealed that computers without any protection against spyware and malware were 40% more likely to be infected.
