Researchers spotted a malvertising campaign that used poisoned ads on Skype to redirect users to the Angler exploit kit. The video chat technology has been leveraged by attackers to disseminate malicious ads for three years in a row. This latest campaign clearly demonstrates that platforms that display ads, even when they are not the browser, are not immune from malvertising attacks. It would be a good idea to install an ad-blocker to protect against those pesky browser-based apps. Installing an anti-virus solution will provide added protection if attackers decide to migrate their ads to non-browser applications.”]
