Searchmeup Targets Weak PCs
Page 1 of 1
Security firm PandaLabs reported the emergence of Searchmeup, new malware that exploits the LoadImage vulnerability in Microsoft Internet Explorer.
If left unpatched, the vulnerability can take advantage of a buffer overflow condition in the LoadImage API that allows an attacker to infect a machine by simply having a user visit a coded HTML page. The malicious code resides in cursors or image icons on the malicious Web page or HTML e-mail.
The Searchmeup malware component takes advantage of unpatched Windows PCs to infect the user with any number of different malicious payloads, including Trojans, keyloggers and dialers.
Searchmeup hijacks users' browsers and specifies a search engine to change their default homepages to. The search engine then attempts to coerce users into downloading even more malware without knowledge.
"The appearance of Searchmeup is a sign of the continuous evolution of malware, and of adware and spyware in particular," Luis Corrons, director of PandaLabs, said in a statement. "The first stage was that adware reached computers as a component of a freeware application, then Web pages appeared that installed adware on users' computers using ActiveX. Now they have gone a step further, as Searchmeup exploits a vulnerability that even virus creators had not used until now."
A Microsoft spokesperson was not available for comment by press time.
As always, users are advised to keep their PCs updated with the latest patches and most up-to-date virus/malware definitions.
