Notorious Bredolab virus creator is sentenced to prison

The man who elaborated and then spread the Bredolab virus, which infected roughly 30 million computers worldwide, was sentenced to four years in prison by an Armenian district court yesterday, according to Wired.

Georgy Avanesov, a 27-year-old Russian citizen of Armenian descent, was first nabbed in 2010 after Dutch authorities took down a large Bredolab network made up of about 140 different infected computer servers. Shortly after this seizure, global spam levels fell by 12 percent.

Spam continues to dip but malware marches merrily on

Spam may be down, but cybercriminals are keeping busy launching more sophisticated attacks (PDF), according to McAfee's latest Threats Report.

Looking at 2011's final quarter, McAfee found that spam hit its lowest level in years, especially across popular targets such as the U.K., Brazil, Argentina, and South Korea. But the U.S. and Germany saw their rates inch up slightly.

And though spam levels have declined overall, junk mail is still a clear danger because of the increase in spearphishing, or more targeted attacks. In years past, spammers sent their payloads to a slew of random addresses, … Read more

Spam sinks to lowest level in almost three years, says Symantec

Think you're seeing less junk mail in your inbox these days? If so, it's not just your imagination.

The rate of spam across the world has hit close to a three-year low and now encompasses just 70 percent of all e-mails, according to Symantec's November Intelligence Report (PDF).

That number is a healthy drop from 2009 when spam accounted for 90 percent of all global e-mails. And it's close to the 68 percent level seen in late 2008 after the spam hosting ISP McColo was shut down.

In particular, pharmaceutical spam is at its lowest level … Read more

Android's a malware magnet, says McAfee

Malware targeted toward Android devices continues to surge, says a new report from McAfee, pushing 2011 to become the busiest year in history for both mobile and general malware.

The amount of malware infecting Android devices during the third quarter grew almost 37 percent from the second quarter, according to McAfee's Third-Quarter Threats Report (PDF). Android's growing demand among consumers has made it an increasingly ripe and inviting target for cybercriminals.

How inviting? Almost all new mobile malware over the third quarter was aimed squarely at Android. Legacy software being what it is, though, among all mobile platforms, … Read more

The Bredolab botnet was typically used by cybercriminals to send out spam selling fake drugs, according to Fortinet. Spam had actually fallen as much as 26 percent the week after the network was dismantled but was able to stage a bit of a recovery afterward.

The ever-present Koobface botnet, … Read more
