Researchers Discovery Data-Stealing Malware That Likes to Nap

JB

Researchers at FireEye's Malware Intelligence Lab say they've found malware that attempts to evade detection with extended sleep calls and uses "the fast flux technique" to hide the attacker's identity.

They are calling the malicious downloader "Trojan Nap" and notes it is akin to the malware used in the recent New York Times breach in which university computer were manipulated to continually churn out different IP addresses from around the globe, making the correct one more difficult to find.

By using extended sleep calls -- up to 10 minutes versus the normal seconds, according to VentureBeat -- the trojan avoids tripping automated analysis systems that otherwise would capture its behavior.
