Intego reports a “new, improved” beta version of the Blackhole RAT (Remote Adminstration Tool/Trojan), though the company still doesn’t seem to think much of the thing. Logically enough, it calls this version OSX/BlackHoleRAT.B. However, this seems to be much the same as the variants reported by SecureMac on February 25th: http://www.securemac.com/blackholerat-bulletin.php.

I’ve already cracked the joke about this being a non-Event Horizon elsewhere, but you didn’t think I wasn’t going to use it again, did you?
