Ny "sofistikerad Trojan" som kallas SpamThru

http://www.techworld.com/news/index.cfm?RSS&NewsID=7175

Den kallas SpamThru och ska tydligen vara en väldigt "sofistikerad trojan".

"Security experts have discovered new spambot software that installs its own anti-virus scanner to eliminate competition, alongside a number of other sophisticated features."

""SpamThru is a money-making operation, and the author takes great care to make sure that detection by the major vendors is avoided by frequently updating the code," said SecureWorks' Joe Stewart in the company's analysis."

"SpamThru is a Trojan that turns a system into part of a network of bots designed to send out spam, a type of operation that's been around for several years. While the Trojan's network doesn't seem especially large so far - at a couple of thousand of bots - SpamThru shows that criminals are now able to treat spam software development just like any other commercial development endeavour, Stewart said."

"It patches the license signature check in-memory in the Kaspersky DLL in order to avoid having Kaspersky refuse to run due to an invalid or expired license," Stewart wrote. It uses a custom peer-to-peer protocol to control communication with the network, which makes the bot network harder to kill. "Control is still maintained by a central server, but in case the control server is shut down, the spammer can update the rest of the peers with the location of a new control server, as long as he/she controls at least one peer," Stewart wrote.

Each client has its own spam engine, creating spam from a template that's transmitted usiung AES encryption to avoid giving access to competing spammers, SecureWorks said.

Känner mig ledsen för er med Windows som får stå ut med all virus skit, men, för er som inte orkar läsa citaten så är det en trojan som (inte helt oväntat) vill tjäna pengar. Det den gör är att blockera andra antivirus program att uppdateras och använder i stället sitt egna ondskefulla program. Den verkar kunna angripa Kaspersky. Får väl hoppas att alla antivirusmakare snabbt göra en fix mot denna trojan och ni bör kolla updates på antiviruset ganska ofta.
