New TDL-4 Bot Trojan Nearly “Indestructible,” States Kaspersky

According to Kaspersky the security company, its researchers have named malicious software TDSS' most recent variant as TDL-4, which's currently the most advanced and complicated malware inside the online-crooks' store of weapons. Fudzilla reported this on June 29, 2011.

Stated Sergey Golovanov researcher with Kaspersky Lab in an elaborate study on June 27, 2011, TDL-4 the name assigned to a bot Trojan, which contaminated PCs, and assembled hijacked machines resulting thereof, was the most advanced e-threat on the present date. ComputerWorld reported this on June 29, 2011.

Said Kaspersky, the malware utilized well-refined techniques for contaminating a computer, regulating the computer from remote, concealing the tracks TDL-4 left behind as well as readying the hijacked computer to load additional malware. It had also let its creator build a botnet comprising millions of compromised PCs, the company added.

Researchers at Kaspersky reportedly, studied TDL-4's newer version as also assessed its fresh abilities to find that the malware was able to utilize P2P (peer-to-peer) file-sharing networks.

According to director of malware research Joe Stewart for Dell SecureWorks, who's also a botnet specialist known internationally, he doesn't believe that the Trojan cannot be perfectly destroyed; however, it's quite indestructible, adding that it performs very well in staying on. ComputerWorld published this on June 29, 2011.

Stated Kaspersky, in addition to creating a botnet that well evaded anti-virus engines and rival Trojans, TDL-4 could currently erase some 20 extremely well-known competing Trojans loaded onto a contaminated system, including ZeuS, Optima and Gbot. CBR reported this on June 29, 2011.

Moreover, TDSS itself plants some 30 utilities onto a target computer, including phony AV software and systems that raise distributing spam and advertising traffic. As per Kaspersky, online crooks provided unidentified access services through contaminated PCs at a price of $100 per service, per month.

Conclusively, in a warning Sergey Golovanov along with Igor Sumenkov stated that TDL-4 had been modified for creating a botnet that could well elude AV firms and rivals alike. Also, it'd well let access to contaminated PCs despite each and every C&C server shutdown, thus published Fudzilla in news on June 29, 2011.
