Threat Metric

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

The following fields listed on the Threat Meter containing a specific value, are explained in detail below:

Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.

Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.

Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.

Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.

% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

Sinit is a backdoor Trojan that allows criminals to access your PC and connects the system to a distributed botnet. Botnets are often exploited for illegal attacks (such as DDoS strikes that overload websites with artificial traffic) and PCs that are forced to participate in botnets have a high chance of experiencing instability due to unusual resource usage. Although Sinit was most notable in 2005 and 2006, SpywareRemove.com malware researchers have found that Sinit remains functional for many versions of Windows. Despite its age, Sinit should be rated as a meaningful breach of security and privacy, and deleting Sinit should utilize anti-malware programs as available.

Why You Don't Want Your PC Dragged into Sinit's Bot Army

Sinit isn't an especially famous example of a backdoor Trojan, but SpywareRemove.com malware analysts have found Sinit's capabilities to be no less dangerous than that of more well-known PC threats than itself. Like many Trojans, Sinit is designed to be able to update itself (in Sinit's case, by using a public-key infrastructure or PKI, which is often used for digital certificates) and can, in spite of its age, still be a danger to PCs as of the time of this writing. Sinit's inclusion of encryption also protects Sinit against casual detection methods, although appropriately-advanced security programs still should be capable of detecting and removing Sinit as is required.

Sinit launches itself automatically and opens a UPD port at random, which allows Sinit to transfer information to and from its botnet. These botnets, collections of other computers that are infected by Sinit, use an unusually advanced (for its time) discovery protocol that allows for the dynamic addition of new 'bots' to the collective. Once your computer is part of the botnet, it may be used to distribute Sinit, send configuration data to other copies of Sinit, provide updates for Sinit or be the recipient of botnet-based attacks against itself. However, botnets are most well-known for being used to conduct spamming campaigns and traffic-flooding attacks against third parties. The variable nature of the attacks causes SpywareRemove.com malware researchers to note that there aren't distinct symptoms of Sinit infections, although degradation of system performance is probable.

Where the Sting in Sinit's Silent Recruitment Comes into Play

Sinit can be used to steal confidential information (passwords, login names, etc), download other PC threats, change your system settings or delete programs. SpywareRemove.com malware experts consider Sinit to be a medium to potentially high level threat and recommend anti-malware scans after any possible Sinit infection. Major aliases for Sinit Trojans include Win32.Sinit, Troj/BDSinit, Backdoor:Win32/Sinit, BackDoor.BAM, Backdoor.Sinit and BKDR_SINIT.A.

As an older PC threat than most, Sinit is compatible with older versions of Windows. Windows 95, Windows 98, Windows 2000, Windows Server 2003, Windows Me, Windows NT and Windows XP all are affected by Sinit attacks. SpywareRemove.com malware researchers also mention that, while Sinit hasn't shown any capabilities for infecting Windows 7, the same can't be said for similar backdoor Trojans of more recent origin than Sinit.
