Mac Trojan spotted
TrendMicro has spotted another Domain Naming System (DNS) Trojan targeting Mac systems. The malware, known as OSX/Jahlav-D, masquerades as a MacCinema Installer. Users are prompted to update QuickTime Player by downloading a QuickTimeUpdate.dmg file.
The Trojan affects systems in the same was as its predecessor, OSX/Jahlav-C, which was spotted in June. Most encounters involve websites hosting video content. Once infected, the malware allows a user's web traffic to be diverted to malicious locations such as phishing sites.
To avoid infection, users are advised to avoid downloading or installing Mac software updates from sources other than Apple.
