Backdoor.Tidserv

Backdoor.Tidserv Description

Backdoor.Tidserv is a malicious backdoor Trojan that allows criminals to gain access to the infected machine from a remote location. A backdoor is simply an opening in the infected computer's security that allows criminals to gain unfettered access to it while bypassing the infected computer's security measures, much like a robber can gain access to an unguarded building by using an open back door. Backdoor.Tidserv uses advanced rootkit techniques in order to avoid detection or removal. ESG security researchers have observed that Backdoor.Tidserv can cause browser redirects and erratic behavior. This browser hijacking component is commonly referred to as the 'Google Redirect Virus' due to its propensity for derailing Google search result. ESG security researchers strongly recommend removing Backdoor.Tidserv with an advanced anti-malware solution with anti-rootkit capabilities. Backdoor.Tidserv is part of the infamous TDSS rootkit family and will often be identified by a variety of aliases, including such names as Backdoor:W32/TDSS, BKDR_TDSS, Win32/Alureon, Trojan-Dropper.Win32.TDSS, and Packed.Win32.TDSS.

Criminals use Backdoor.Tidserv in order to profit from pay per click marketing and advertising revenue. To do this, they force the infected computer system to visit certain websites that are set up so that they will generate revenue depending on the number of visits and how many times certain links or advertisements are clicked. Backdoor.Tidserv is installed on the victim's computer without the victim's knowledge or authorization, usually through social engineering techniques such as malicious email attachments or misleading online advertisements that use JavaScript exploits to install Backdoor.Tidserv. Once installed, Backdoor.Tidserv uses rootkit techniques in order to hide from common anti-malware programs. This means that the victim may experience symptoms of a Backdoor.Tidserv attack while their anti-malware program indicates that there is nothing wrong. To remove Backdoor.Tidserv, a specialized anti-rootkit tool may be necessary.

Backdoor.Tidserv's Dangerous Payload

Backdoor.Tidserv has a master boot record rootkit, making changes that allow this Trojan to load automatically when Windows starts up. Because of Backdoor.Tidserv's advanced rootkit techniques, this automatic loading of Backdoor.Tidserv can bypass very stringent security measures on the victim's computer system. Backdoor.Tidserv has the capacity to install malicious files, connect to a remote server and download or execute files, delete files on the infected computer, make changes to the Windows Registry, reconfigure itself, and make changes to the infected computer's security that allow cybercrooks to gain illegitimate access to the infected machine.
