The Macintosh Security site SecureMac recently made an announcement about a new Mac Trojan horse they claimed to have discovered, and subsequently named Boonana. In their the-sky-is-falling report, they state that Boonana is disguising itself as a video and is being distributed through social networking sites like Facebook and Twitter via a “Is this you in this video?” link. Like all other Mac Trojan horses, this one requires the user type in an administrative password to install.

Shortly after SecureMac’s report, Intego posted a security memo stating they had been monitoring this Trojan, previously identified it as Koobface. Intego goes on to state that they did not publically issue information about Koobface/Boonana because it’s install mechanism is flawed, and even if you downloaded and installed it, it doesn’t actually install properly.
