A virus that specifically targets certain Windows NT operating systems has been discovered “in the wild.”
The virus, named “Infis,” is the first such code to be observed outside the laboratory setting, according to Kaspersky Lab, a Moscow-based antivirus software firm.
The malicious code is considered more of a technical feat than a threat to NT users worldwide, since it lacks a destructive payload or the ability to replicate itself over the Internet. Its claim to fame is its ability to gain control of the “system level,” or core operations, of Windows NT.
Infis is a file memory resident virus aimed at Windows NT 4.0 with Service Packs 2, 3, 4, 5, 6 installed. It does not affect Windows 95/98, Windows 2000, or other versions of NT.
Although Infis does not carry any destructive payload, it contains errors that corrupt some files when infecting them, according to the lab.
