Sinit is a dangerous computer worm and Trojan that received widespread attention in October of 2003. Today, the risk of infection with variants of the Sinit worm is quite low due to the fact that this threat has been around for a long time, and most computers are well protected from this menace. The last recorded attacks by a Sinit variant that received important attention took place in 2007. Although Sinit has numerous aliases, Sinit is typically a backdoor Trojan with basic worm-like tendencies. Due to its age, Sinit variants have a hard time infecting recent versions of the Windows operating system. In general, Windows Vista and Windows 7 are well guarded against this threat. However, Windows XP and previous versions of this operating system are vulnerable to this malware infection.

The Sinit attack is usually composed of a backdoor Trojan which makes it possible for criminals to gain access to the compromised computer. This is done by opening a UDP port chosen at random. By using this port, criminals can steal information from the infected computer and install other malware on the compromised computer without the victim's authorization. Sinit is a Trojan written in C++ and is compressed using UPX in order to allow Sinit to occupy less space and to be more difficult to analyze. Due to the fact that the Sinit Trojan has been around for a long time, most anti-malware applications that are fully updated can remove and detect this malware threat with few problems. It is also rare to find computers that are infected with this Trojan due to the fact that most infections involving Sinit variants occurred in 2003.

When Sinit is installed on the victim's computer, Sinit makes changes to the Windows Registry that allow Sinit to run automatically in the background. Like many worms, Sinit will typically copy itself to the System folder and removable memory devices connected to the infected computer. Once Sinit has altered your system settings to ensure that Sinit runs impromptu every time the victim logs into Windows, Sinit opens a UDP port at random. By using this open UDP port (commonly known as a backdoor), criminals can obtain information on your computer, perform tasks and actions on the infected computer, spy on your activity, install other malware and alter your system settings without your authorization.
