Botnets spread spam and infections, launch denial of service attacks, conduct click fraud campaigns and hijack online bank accounts.Īnd botnets increasingly are being used by crime rings and spying collectives to infiltrate and plunder company and government networks. They then sent instructions for the botnets to repeatedly click on certain ads as part of a click fraud scheme designed to trigger payments to the crooks.īotnets are the highly versatile power plants of cybercrime and are often comprised of 10,000 or more infected computers that respond to commands from a lone controller. The bad guys’ end game, in this particular instance, was to replenish networks of infected computers known as a botnets. “By compromising these high-profile websites, they were able to direct a lot of traffic to a malicious server that then infects computers with additional malware,” says Stone-Gross. This cloaking technique has helped the bad guys sustain drive-by infections on, a high-traffic do-it-yourself site, and on, a nutrition and fitness site. Criminals use steganography to make malware downloaders largely invisible to antivirus filters and cleanup tools. Specifically, Stone-Gross uncovered the latest techniques bad guys are using for hiding something called a malware downloader, whose function is to relay commands to an infected computer. In a drive-by download, malicious software gets inserted into the web browser of an unsuspecting Internet user- just by navigating to a corrupted web page. Now cybercriminals have adapted the technique to help them carry out drive-by download infections, according to research findings disclosed at the Black Hat conference here this morning by Dell SecureWorks senior researcher Dr. Steganography-the craft of hiding something seemingly out in the open-is an old secret agent trick. LAS VEGAS – Cyber gangs have begun using the digital equivalent of invisible ink to disguise the malicious coding that helps them take control of your computer and put it to criminal use.
