Backdoor.Wualess

Backdoor.Wualess is one of various Trojans that are distributed by the so-called 'Comment Crew,' a group of criminals that use HTML comments to conceal communication between backdoor Trojans and their Command & Control servers. Although Backdoor.Wualess is one of the Comment Crew's oldest Trojans and has a limited distribution as of 2013, SpywareRemove.com malware experts warn that Backdoor.Wualess still includes attack functions that can compromise your PC's security and steal information in a wide range of ways. E-mail is the most likely infection vector for Backdoor.Wualess attacks, and, if you do have any cause to suspect that your PC might be infected, anti-malware software should be your first resort for removing Backdoor.Wualess safely.

Backdoor.Wualess and other Trojans that are distributed by the same gang of criminals usually are used in targeted attacks for specific companies, instead of spam attacks against the general public.

Companies attacked by Backdoor.Wualess and related PC threats include those in the financial sector, the energy industries, telecommunications companies and some public service groups, amongst others. These attacks are a global phenomenon, with particularly high percentages reported for the United States, India, Eurasia and China.
