New Windows virus attacks PHP, HTML, and ASP scripts
Researchers have identified a new strain of malware that can spread rapidly from machine to machine using a variety of infection techniques, including the poisoning of webservers, which then go on to contaminate visitors.
The malware is a variation of a rapidly mutating virus alternately known as Virut and Virux. It has long proved adept at injecting itself into executable files, which are then able to attack uninfected machines through network drives and USB sticks.
The variant, which Microsoft is calling Virus:Win32/Virus.BM, is also able to infect web scripts based on languages such as PHP, ASP, and HTML. Servers that become infected include an iframe in webpages that attempt to spread malware to visitors.
"This catapults the possibility of spreading even farther," Trend Micro researchers warn. "If the script files happen to be uploaded to a publicly accessible website, any visitor to the affected sites will be led to the URL embedded in the iframe code."
