Report: Malware Delivery Technique Focus On HTML Attachments

Standard brands used to spread malware, according to Commtouch's third quarter Internet Threats Trend Report
Sunnyvale, Calif. October 18, 2010 Use of malicious HTML email attachments increased significantly in the third quarter, Commtouch' (Nasdaq: CTCH) reported today in its third quarter Internet Threats Trend Report. The HTML attachments displayed phishing pages on the users local computer or redirected users to sites hosting malware or spam products.

The Q3 report examines the methodology within blended attacks, such as the Here You Have worm, which spread widely in September using Outlook contact lists from infected PCs. Both Here You Have and numerous fake LinkedIn invitations relied on a combination of social engineering and masked hyperlinks to lead users to websites with malware scripts.

During Q3, the PayPal, LinkedIn, CraigsList, Bell Canada, NewEgg and Amazon brands were used by spammers to inspire action by consumers. The report also features the unusual bedfellows of a pharmacy spam campaign based on solidarity with several European politicians and celebrities.

Commtouchs quarterly trend report reflects the results of its analysis of billions of Internet transactions daily within the companys cloud-based GlobalView Network. With the acquisition of the Command Antivirus division of Authentium (now known as SafeCentral), Commtouch also has added the malware analysis capabilities of the Command AV labs.

Other highlights from the Q3 Trend Report include:

* Spam levels averaged 88% of all email traffic throughout the quarter, peaking at over 95% in mid-September with 198 billion spam/phishing messages per day. By comparison, Q2 spam levels averaged 80% of all email, with 179 billion spam/phishing messages per day.

* Approximately 339,000 zombies were activated daily, almost 30,000 more per day than in the previous quarter.
