BackDoor.Bulknet.739 Description


BackDoor.Bulknet.739 is a backdoor Trojan that, in conjunction with a second PC threat (BackDoor.Bulknet.847) uses an infected PC’s resources to send automated spam e-mail for malware distribution and other malicious purposes. In a victory for PC security, the Russian AV company known as Doctor Web recently managed to infiltrate one of BackDoor.Bulknet.739′s botnet servers, allowing them to gain access to useful information on BackDoor.Bulknet.739′s distribution and infection methodology. Despite this positive development, BackDoor.Bulknet.739 still is a danger to PCs that BackDoor.Bulknet.739 infects and may show limited or no symptoms of its attacks. SpywareRemove.com malware experts consider anti-malware software necessary both for removing BackDoor.Bulknet.739 and in many cases, for detecting BackDoor.Bulknet.739 in the first place.

BackDoor.Bulknet.739: the Accurately-Named Trojan with One Step on the Path to Termination


BackDoor.Bulknet.739 is used to enable spam-based e-mail attacks that exploit the resources of any compromised PCs by connecting them to configurable botnets. These botnets issue instructions, typically en mass, to BackDoor.Bulknet.739-infected computers, allowing BackDoor.Bulknet.739 to send its spam or perform other attacks. SpywareRemove.com malware researchers are particularly careful to warn that a BackDoor.Bulknet.739 infection will not show many visible symptoms of the presence of malign software, other than the possibility of BackDoor.Bulknet.739′s repetitive bulk-mailing functions eating your computer’s resources and, as a result, causing performance issues.

BackDoor.Bulknet.739′s campaign was active in 2012 but has been thrown into the spotlight anew after Doctor Web researchers managed to gain control over one of BackDoor.Bulknet.739′s botnet servers.

Getting the Vast Bulk of a BackDoor.Bulknet.739 Problem Out of Your Virtual Door
