WikiLeaks website defaced by OurMine hacking group, who left a message on the site. OurMine is a Saudi Arabian group of hackers which claims to be a “white hat” security firm. The group markets itself by taking over social media accounts of high-profile targets and then encouraging them to contact the hacking group to buy its IT security service in an effort to protect themselves from future cyber attacks. The site administrators regained access to their DNS server and at the time of writing, the WikiLeaks website is back online.
