McAfee sees surge in spam, Koobface samples, MBR attacks

The first three months of 2013 have seen a surge in spam volume, as well as large numbers of samples of the Koobface social networking worm and master boot record (MBR) infecting malware, according to antivirus vendor McAfee.

After remaining relatively stable throughout 2012, spam levels rose during the first quarter of 2013, reaching the highest volume seen in the past two years, McAfee said in a report released Monday.

The amount of spam originating from some countries rose dramatically, McAfee said. Spam from Belarus increased by 540 percent while spam originating in Kazakhstan grew 150 percent.

Cutwail, also known as Pushdo, was the most prevalent spam-sending botnet during the first quarter, McAfee said.
