The malware, a variant of online virus and worm, has been specifically seen affecting operating systems running on Windows in the recent past.

"It has been observed that the variants of malware named as 'dorkbot' targeting windows operating systems, are spreading”, a latest advisory issued by the Computer Emergency Response Team of India (CERT-In) said.

The CERT-In is the nodal agency to combat hacking, phishing and to fortify security-related defences of the Indian internet domain.

The deadly virus, with almost a dozen aliases, is capable of stealing sensitive information from infected machine including stored passwords, browser data, cookies and has a smart and lethal potential to take complete control of the affected system, it said.

The cyber security agency said the malware can hide itself by over-writing, can collect system information such as OS (operating system) information, user privileges and apps installed on the system and can act to aid remote access of the infected machine to an attacker.

It destructs and infects a system by acquiring fake identities of Facebook, Skype or any other social media platform and lowers its immunity against a potential virus attack.

"To hide itself from detecting by anti-virus solutions, the malware injects its code into files like cmd.exe, ipconfig.exe, regedit.exe, regsvr32.exe, rundll32.exe, verclsid.exe and explorer.exe," the advisory said.
