Spam Is At A Two-Year High

Spam – particularly the kind with malicious attachments – is enjoying a growth spurt, reaching a two-year high overall, which includes the spike last fall just before the SpamIt operation folded its doors, a security firm says.

In fact spam traffic is about double what it was then, according to M86 Security Labs, which analyzes spam levels across selected domains.

“After multiple recent botnet takedowns, cybercriminal groups remain resilient clearly looking to build their botnets and distribute more fake AV in the process,” the company says in its blog. “It seems spammers have returned from a holiday break and are enthusiastically back to work.”

This report coincides with a report yesterday from Internet security company Commtouch, which says a spike in email-attached malware has just ended, but that further waves are expected.

M86 says in its blog that most of the spam is generated by the Cutwail botnet, and malicious spam accounted for 13% of the mix over the past week, which is unusually high, but even that spiked to 24% yesterday.
