Our team at Nominum recently looked at the biggest threats to fixed networks at the DNS layer. Why the DNS layer? Because it is ubiquitous -- every network runs on it -- and it is the best option for protecting critical infrastructure.
It's been about a year since Conficker/Downadup hit in 2009, and although the threat didn't turn out to be as grave as it had the potential to be, the 6.5 million PCs that remain infected today represent what Symantec Corp. calls a "loaded gun, waiting to be fired."
More than a year after doomsday reports hinted that the Conficker worm would bring down the Internet, one-in-10 Windows PCs still have not been patched to plug the hole the worm wriggles through, new data shows.
A report from security research firm NetWitness about a malicious botnet dubbed Kneber has been the focus of a fair amount of media attention, but mostly sensationalism that misses the real point.
Russia and Brazil are now the top hotspots for global Internet attack traffic, Net giant Akamai has said in its latest threat report, placing most of the blame on the hardy Conficker worm.
Creators of Waledac malware enlisted the Conficker botnet as a tool to spread malware of their own, marking the first time Conficker was made available for hire, according to Cisco's mid-year security report.This was symptomatic of a wider trend Cisco noted of malware purveyors using established business practices to expand their illegal enterprises. Cisco likened the arrangement between Waledac and Conficker to a partner ecosystem, a term Cisco uses to describe its collaboration with other vendors.
