A DNS-changing trojan targeting Macintosh computers is making the rounds, disguised as a “MacCinema Installer,” Dave Marcus, director of security research and communications for McAfee Avert Labs, told SCMagazineUS.com Wednesday. The latest variant, called OSX/Puper.a, was identified in late March, but researchers detected a new sample this week. Users are being prompted to download the malware when trying to view certain online videos, Marcus said. If infected, a victim’s web traffic could be diverted to website of the attacker’s choosing. — AM
