"Hey, it's OurMine we are just testing your security, please contact us for more information, Thanks," the group wrote in a message posted along with its logo in each case.

WWE confirmed the breaches in a statement to Mashable saying: "WWE can confirm that several official WWE Twitter accounts were hacked for a brief period on Saturday evening.
