Virus writers have grafted a network sniffer into the latest variant of the SDBot worm series.<\/p>\n","protected":false},"excerpt":{"rendered":"
So far there are no reports of SDBot-UH in the wild but the inclusion of selective network sniffing along with keystroke logging features and other backdoor capabilities has security researchers worried.<\/p>\n
Sniffers are designed to monitor network traffic. They are widely used for network performance diagnostics but in this instance their function has been turned to malign purposes. Bundling a network sniffer with an auto-propagating worm makes it easier for hackers to harvest usernames and passwords than would otherwise be the case.<\/p>\n
The sniffing capabilities of SDBot-UH worm focus on phrases associated with network logins and Paypal accounts. It also tries to steal the CD keys of games, according to an advisory by AV firm Trend Micro.<\/p>\n
Patrick Nolan, a security researcher at the Internet Storm Center, warns: “If the Trojans described by Trend can successfully transmit the filter’s packet captures back to the owner, they are going to cause problems well beyond typical bot infestation issues.”<\/p>\n
SDBot-UH uses a variety of well-known Microsoft exploits to spread. It also looks for weak usernames and passwords to gain access to target machines. Malicious sniffers can be difficult to detect but Netcraft points to a number of tools such as Sentinel and AntiSniff that can be used to detect sniffers on a network.<\/p>\n
