The notorious hacking group OurMine has claimed credit for defacing Mark Zuckerbergs online accounts. The group admitted having exploited a flaw in Pinterest but avoided to reveal it. Zuckerberg had enabled two-factor authentication after they hacked it for the first time. The OurMine group is linked to a Security Firm that is trying to obtain notoriety from the attacks and is offering its services to the targets that evidently need them to avoid further incidents. The list of victims is very long and include names like Mark Zuckerberg, Twitter co-founder Evan Williams, David Guetta Daniel Ek, former Twitter CEO Dick Costolo, the CEO and founder of Spotify, Google CEO Sundar Pichai.”]
