Yahoo users hit by 'malvertising' campaign

Company uses advertising space on Yahoo's websites in an attempt to install malware on users' computers

Yahoo users have become the target of one of the biggest "malvertising" attacks every, after a malware company bought advertising space on the company's websites to deliver malicious adverts in an attempt to install malware on users' computers.

The malvertising campaign attempted to use a vulnerability in Adobe's Flash to install the software, which tends to be a mixture of ad fraud and ransomware programs.
