sl4shd0rk writes "A new Mac OS X exploit was discovered Friday morning by Kaspersky Labs which propogates through a zipfile attachment. The attachment tricks the Mac user into installing a variant of the MaControl backdoor via point-and-grunt. Embedded in the virus is an encrypted IP address belonging to a server in China which is believed to be a C+C server. Once installed, the virus opens a backdoor allowing the attacker on the C+C server to run commands on the compromised machine. Shortly after Kaspersky's announcement, AlienVault Labs claims to have found a similar version of the Mac malware which infects Windows machines. The Windows version appears to be a variant of the Gh0st RAT malware used last month in targeted attacks against Central Tibetan Administration. Both viruses are suspected of being tools in a campaign to attack Uyghur Activists."
