A new Trojan horse malware that affects Mac OS X has been uncovered by Macintosh Security site SecureMac.
The Trojan is called 'trojan.osx.boonana.a' and is being disguised as a video and distributed through social-networking sites such as Facebook. It appears on people's Facebook pages and may contain the text "Is this you in this video?" in the link. When the link is clicked, the Trojan runs a Java applet that downloads other files to the computer and automatically opens an installer.
The Trojan will then run in the background and appears to report system information to servers on the internet, leading to a potential breach of personal information. The Trojan also attempts to spread itself by sending spam email messages from the user's account.
