Bot attacks Linux and Mac but can't lock down its booty

"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.
