Microsoft is an innovator in more ways than one, with some innovations having more merit than others, and the Redmond company is now advancing into new territories for the sake of protecting customers. Tim Cranton, associate general counsel, revealed that Microsoft filed no less than five civil lawsuits in the King County Superior Court in Seattle (State of Washington) in a move designed to tackle malvertising. The term describes a practice of malicious online advertising, and the five legal actions debuted are the first of their kind, opening a new front designed to ensure that end users are secure while online. Cranton noted that the software giant was collaborating actively with providers of online ad platforms in order to fight malvertising, and that the lawsuits filed represented a fresh push in this direction.

“Malvertising works by camouflaging malicious code as harmless online advertisements. These ads then lead to harmful or deceptive content,” Cranton noted. “For example, ads may redirect users to a website that advertises rogue security software, also known as scareware, that falsely claims to detect or prevent threats on the computer. Malvertising may also directly infect a victim’s computer with malicious software like Trojans – programs that can damage data, steal personal information or even bring the users’ computer under the control of a remote operator.”

The Redmond company alleges that “Soft Solutions,” “Direct Ad,” “qiweroqw.com,” “ITmeter INC.” and “ote2008.info” were all involved in serving malvertisements. Unsuspecting users have either fallen victim to malicious software or were deceived to pay for the removal of inexistent malware by scareware programs. Microsoft noted that it didn’t know the identity of the individuals behind the companies it was alleging that were involved in offering malicious advertisements, but that the lawsuits were designed to bring those responsible to justice.

“Adopting a few good habits can help you avoid online scams and ensure the safest computing experience possible: make sure you’re using legitimate and up-to-date anti-virus, firewall and anti-malware/spyware tools. Be extra cautious about offers to secure or scan your computer with security software or programs you don’t recognize. Don’t give out personal information or credit card information unless you know the site is secure,” Cranton added.
