Hackers broke into at least 34 servers belonging to Comcast, dumping what appears to be a list of the company’s mail servers, passwords and a link to the root file that contains the vulnerability they used to penetrate the system. The hacktivist collective NullCrew has claimed to have hacked a handful of corporations over the years, Sony, PayPal, Orange Telecom and Ford just to name a few, and took credit for the attack against Comcast Wednesday, on its official Twitter handle, @NullCrew_FTS.
