Report about hack threat to Tibetan activists used as lure in malware attack
Hackers trick Tibetan activists into visiting exploit pages by baiting them with a legitimate report from AlienVault

IDG News Service - Hackers are using a recent report about cyberthreats to Tibetan activists as a lure in a new attack against pro-Tibet organizations that distributes Windows and Mac malware, researchers from security vendor AlienVault said Monday.
On March 13, AlienVault published a report about email-based cyberattacks against Tibetan activist organizations including the Central Tibet Administration and the International Campaign for Tibet.
The rogue emails seen in those attacks distributed a booby-trapped Word document that exploited a Microsoft Office vulnerability (designated CVE-2010-3333) to install a variant of Gh0st RAT, a remote access computer Trojan.
AlienVault researchers believe that the Tibet attack campaign was organized by the same group of Chinese hackers that launched the so-called Nitro attacks against dozens of chemical sector companies last year.
However, it seems that even though the cyberespionage operation was exposed, hackers haven't given up on targeting pro-Tibet organizations. In fact, they started using AlienVault's report about the campaign as a lure in new attacks against Tibetan activists, said AlienVault researcher Jaime Blasco in a blog post on Monday.
Newly intercepted rogue emails that use spoofed headers to appear as originating from AlienVault warn recipients that Tibetan activist organizations have been targeted in recent cyberattacks.
Successful exploitation attempts result in computer backdoors being installed on both Windows and Mac OS X systems. The Mac backdoor had a zero detection rate on VirusTotal when scanned by AlienVault on Monday, Blasco said. Now, it is detected by six out of the 43 antivirus engines used by the service.
The Mac piece of malware connects to a command and control server hosted on a domain name that was associated in the past with attacks involving the Protux backdoor, Blasco said.
It's not clear whether the Nitro gang is responsible for the new attacks against Tibetan activists, but the group is known to have used similar techniques before. In December 2011, Symantec reported a series of malicious emails sent by the Nitro gang that used the company's original report about the group's operations as a lure.
