Malvertisement Campaigns

Ads are one of the primary sources of revenue for many app developers and website owners, and they help authors bring quality content. However it’s worth noting that some platforms are targeted by malware writers to distribute their stuff and infect users on a massive scale. Here are some cases — check out Malvertising Via Skype Delivers Angler | F-Secure, Users Report Malicious Ads in Skype | Threatpost, and Skype serving virus-laden ads – Skype Community.

Those ads mislead users to believe that they’re genuine dialog boxes by the respective software — WMP and Flash, and create a sense of urgency. Clicking on the ad, as a Skype user reports, “will take you to a site pretending to be Adobe and try to download viruses to your machine.

Malvertising concern is one good reason to block ads in Skype. Hope Skype improves the ads quality and further tightens the grip on its ad delivery system, although malicious Skype ad campaigns may be rare occurrences.
