The botnet known as Win32/Kelihos keeps on infecting, now touting a YouTube video of the Boston Marathon bombing that comes with a malicious iframe pointing to a Redkit exploit page that infects viewers.

Could distributed denial of service (DDoS) malware be evolving to defeat anti-DDoS security measures like CloudFlare? We do not usually see a lot of innovative denial-of-service malware in our day-to-day work. What we do see usually boils down to the basic flooding techniques: TCP Syn, UDP and ping floods, and sometimes HTTP-oriented floods. Of course,

Malware authors have a solid track record in regards to creative Command and Control protocols. We’ve seen peer-to-peer protocols, some custom (Sality), some standard (Win32/Storm uses the eDonkey P2P protocol).

Malware authors have a solid track record in regards to creative Command and Control protocols. We’ve seen peer-to-peer protocols, some custom (Sality), some standard (Win32/Storm uses the eDonkey P2P protocol). We’ve seen binary protocols (Win32/Peerfrag, aka Palevo). We’ve seen other custom protocols that leverage other standard protocols such as HTTP (Win32/Georbot), DNS (Morto)and IRC (Win32/AutoRun.IRCBot.AK),

The Flashback trojan has been all over the news lately, but it is not the only Mac malware threat out there at the moment. A few weeks ago, we published a technical analysis of OSX/Lamadai.A, the Mac OS X payload of a multi-platform attack exploiting the Java vulnerability CVE-2011-3544 to infect its victims. OSX/Lamadai.A has

Earlier this month, researchers from AlienVault and Intego reported a new malware attack targeting Tibetan NGOs (Non-Governmental Organizations). The attack consisted of luring the victim into visiting a malicious website, which then would drop a malicious payload on the target’s computer using Java vulnerability CVE-2011-3544 and execute it. The webserver would serve a platform-specific JAR
