The company delivers an opinion SecureMac security following the discovery of a Trojan horse that wants to Mac OS X 10.4 and 10.5. The security risk is described as critical.
SecureMac claims to have discovered several variations of a new Trojan horse targeting Mac OS X 10.4 and 10.5. Loosened the Web wild animal gallops through sharing networks are distributed by iChat and LimeWire. It takes the form of a script compiled AppleScript weighing 60 ko and bearing the name of ASthtv05 barbaric, even as an application of 3.1 Mo, Astht_v06.
For an infection, the user must download and run, the Trojan will then stay in the folder / Library / Caches / “and will launch at each startup.
Tremble Mac Users (?)
According SecureMac, Trojan act with discretion and allows a remote attacker to gain access to vulnerable system. It can transmit user passwords, and escapes detection by opening up ports in the firewall and disabling the system messages. To finish brushing the blackboard, SecureMac adds that the Trojan horse on board an impactor recorder, can enable sharing of files, make screenshots even photos applying for the iSight.
Nothing really gratifying a priori for this malware that exploits a recently discovered vulnerability in Apple Remote Desktop, an application that allows remote administration of computers. Via this vulnerability administrator rights are unduly granted.
Apple will soon provide a fix for the vulnerability, cutting the grass under the feet of the Trojan horse. In the meantime, SecureMac proposes obviously … its security solution. Still, this malware comes the ranks, still very skinny, threats targeting specifically to Mac OS X. In Mac OS, as elsewhere, users should exercise caution in downloading not do anything. Perhaps this is a tangible sign of the growing popularity of the OS company to the apple.
