Ads On Skype Spreading Ransomware

Cyber Criminals have managed to show ads to Skype users who were trying to infect computers with ransomware, says anti-virus firm F-Secure. Although the ads appeared within Skype, does not mean that the browser is not open to advertising.

In the case of observed infected ads which showed the browser unnoticed load a page with the Angler-exploitkit. This exploitkit uses known vulnerabilities in Adobe Flash Player to infect computers with malware. Users who had not patched their Flash Player could become so infected with the Tesla Crypt-ransomware. Like other ransomware encrypts Tesla Crypt sorts files for ransom. The ads on Skype came from the AppNexus-advertising platform, which in the past often for the spread of infectious advertisements used. Meanwhile, the offending ads are no longer displayed.
