From the department of cosmic justice comes this gem, spotted by researchers from Symantec: a trojan that targets Windows, Mac, and Linux computers contains gaping security vulnerabilities that allow rival criminal gangs to commandeer the infected machines.
Known as Trojan.Jnanabot, or alternately as OSX/Koobface.A or trojan.osx.boonana.a, the bot made waves in October when researchers discovered its Java-based makeup allowed it to attack Mac and Linux machines, not just Windows PCs as is the case with most malware. Once installed, the trojan components are stored in an invisible folder and use strong encryption to keep communications private.
The bot can force its host to take instructions through internet relay chat, perform DDoS attacks, and post fraudulent messages to the victim's Facebook account, among other things.
