INTEGO SECURITY ALERT – January 26, 2009

New Variant of Mac Trojan Horse iServices

Found in Pirated Adobe Photoshop CS4

Exploit: OSX.Trojan.iServices.B Trojan Horse

Discovered: January 25, 2009

Risk: Serious

Description: Intego has discovered a new variant of
the iServices Trojan horse that the company discovered on January 22,
2009. This new Trojan horse, OSX.Trojan.iServices.B, like the previous
version, is found in pirated software distributed via BitTorrent
trackers and other sites containing links to pirated software.
OSX.Trojan.iServices.B Trojan horse is found bundled with copies of
Adobe Photoshop CS4 for Mac. The actual Photoshop installer is clean,
but the Trojan horse is found in a crack application that serializes
the program.

With intel inside macs now face the same crap as Windows users. Get AV software such as the FREEWARE ClamX or buy it and keep it updated. don’t let your mac become part of a botnet. Windows users, I offer the same suggestion. Software Firewalls are good too. close ports you don’t use which is 99% of the ports available.
