The creators of the Flame cyber-espionage threat ordered infected computers still under their control to download and execute a component designed to remove all traces of the malware and prevent forensic analysis, security researchers from Symantec said on Wednesday.
Flame has a built-in feature called SUICIDE that can be used to uninstall the malware from infected computers. However, late last week, Flame's creators decided to distribute a different self-removal module to infected computers that connected to servers still under their control, Symantec's security response team said in a blog post
The module is called browse32.ocx and its most recent version was created on May 9, 2012. "It is unknown why the malware authors decided not to use the SUICIDE functionality, and instead make Flamer perform explicit actions based on a new module," the Symantec researchers said.
