On this week’s Cyber Security Brief, we discuss Symantec’s role in an FBI takedown of ad-fraud infrastructure dubbed Operation Eversion. We also discuss the latest developments in the Facebook/Cambridge Analytica scandal, as well as the most recent activity from Magecart. Also, the dangers of most phishing sites having the padlock sign beside their address, and the curious incident of a security researcher who responsibly reported a vulnerability but was still subsequently reported to the police.
