Mac Trojan Horse Found In Pirated Photoshop CS4

Mac Trojan Horse Found In Pirated Photoshop CS4A new trojan horse variant has been found in pirated versions of Adobe’s latest version of the Photoshop suite, security researchers warned Monday. The trojan horse is considered a “serious” security risk, opening Macs to malicious takeover by remote users.

The Trojan horse, OSX.Trojan.iServices.B, is included in Photoshop CS4 cracking software distributed on file-sharing networks such as BiTorrent, according to security software developer Intego.

“The actual Photoshop installer is clean, but the Trojan horse is found in a crack application,” Intego announced in a statement.

Nearly 5,000 people have downloaded the pirate installer as of 6 a.m. Eastern, the company said.

The crack installs a backdoor in /var/tmp/ and then requests the administrator’s password, launching a backdoor. That backdoor connects to two Internet addressess, allowing the hacker to remotely control a Mac, including downloading infected Mac software.

Just days before, a previous version of the Trojan used infected Macs to conduct distributed denial of service attacks. Since the latest version contacts the same Internet servers, there may be a similar motive, according to the firm.
