A Closer Look at Two Bigtime Botmasters

December 11, 2012

Over the past 18 months, I’ve published a series of posts that provide clues about the possible real-life identities of the men responsible for building some of the largest and most disruptive spam botnets on the planet. I’ve since done a bit more digging into the backgrounds of the individuals thought to be responsible for the Rustock and Waledac spam botnets, which has produced some additional fascinating and corroborating details about these two characters.

Microsoft Fixes Zero-Day, Four Other Flaws in IE

September 21, 2012

Microsoft has released an emergency update for Internet Explorer that fixes at least five vulnerabilities in the default Web browser on Windows, including a zero-day flaw that miscreants have been using to break into vulnerable systems.

The patch, MS12-063, is available through Windows Update or via Automatic Update. If you installed the stopgap “fix it” tool that Microsoft released earlier this week to blunt the threat from the zero-day bug, you need not reverse or remove that fix it before applying this update. The vulnerability resides in IE 7, 8, and 9, on nearly all supported versions of Windows, apart from certain installations of Windows Server 2008 and Windows Server 2012.

Malware Dragnet Snags Millions of Infected PCs

Last week, Microsoft Corp. made headlines when it scored an unconventional if not unprecedented legal victory: Convincing a U.S. court to let it seize control of a Chinese Internet service provider’s network as part of a crackdown on piracy.

I caught up with Microsoft’s chief legal strategist shortly after that order was executed, in a bid to better understand what they were seeing after seizing control over more than 70,000 domains that were closely associated with distributing hundreds of strains of malware. Microsoft said that within hours of the takeover order being granted, it saw more than 35 million unique Internet addresses phoning home those 70,000 malicious domains.
