McAfee has released the Q1 threat report for 2009 indicating that cybercriminals have taken over almost 12 million new IP addresses since January, a 50% increase over 2008. The report also indicates a shift in botnet activity, with the US now hosting the largest percentage of botnet-infected computers (80% of all zombie machines – those machines controlled by spammers and others).
Key Findings from the Threat Report:
- Spam levels are still 30% below their peak levels (due to the November 2008 McColo shutdown), though spam volumes have recovered about 70% so far and are rising (the increase in zombie computers will trend this upward)
- The US accounts for 35% of global spam output
- Servers hosting legitimate content have increased in popularity with malware writers as a means for distributing malicious and illegal content.
- Cybercriminals are increasing their use of URL redirects and Web 2.0 sites to disguise their locations.
- Compared with the overall landscape, the Conficker worm represents a small subset of all threat reports. AutoRun-based malware is detected in far greater numbers than Conficker so far.
McAfee predicts that social networks will continue to offer attackers a popular means for social-entineering attacks, as we saw in Q1 with the Koobface variants being distributed on Facebook. Among other trends, customizing attacks and using fear tactics are also on the rise.
