New Threats as Cybercriminals Turn to Targeted Attacks - Government Technology: "Sophos, an integrated threat management solution firm, has revealed the top 10 malware threats of 2005, in a new in-depth report into the year's most pressing security issues. In a year that has seen the number of new threats rise by 48 percent, the lingering Zafi-D worm has taken the number one spot in the virus chart, while last year's hardest hitting virus, Netsky-P, dropped to second place. In contrast, Sober-Z -- only unleashed in November 2005 -- has already climbed to third place as it continues to disrupt and clog networks worldwide.
The 'Sophos Security Threat Management Report 2005' reveals that on average, one in every 44 e-mails was viral during 2005. This rose to one in 12 during major outbreaks, while 15,907 new malware threats were identified." - PDF - http://www.sophos.com/securityreport2005
