Boonana Trojan for Mac OS X spreads via social media: SecureMac has discovered a new Trojan horse in
the wild that affects Mac OS X, including Snow Leopard (OS X 10.6). The Trojan horse, Trojan.osx.boonana.a,
is spreading through social networking sites, including Facebook, disguised as a video. ... When a user clicks
the infected link, the Trojan initially runs as a Java applet, which downloads other files to the computer,
including an installer, which launches automatically. When run, the installer modifies system files to bypass
the need for passwords, allowing outside access to all files on the system. Additionally, the Trojan sets itself to
run invisibly in the background at startup, and periodically checks in with command and control servers to
report information on the infected system. While running, the Trojan horse hijacks user accounts to spread
itself further via spam messages. Users have reported the Trojan is spreading through e-mail as well as social
media sites. [Date: 27 October 2010; Source: http://www.net-security.org/malware_news.php?id=1509]
