Comcast hasn't told customers or made an official comment yet, but a group of hackers are claiming the largest cable company and home Internet service provider in the nation as prey.
Just weeks after the Target breach, hackers posted online that they had accessed dozens of e-mail servers at Comcast. Now, security bloggers are questioning whether the company is minimizing the severity of the breach.
One week ago, the hacker group known as NullCrew FTS announced via Twitter that they were going after Comcast. Three hours later, a second tweet claimed they had infiltrated 34 mail servers.
Within 20 minutes of the second tweet, a third shared a link to Pastebin, a website where they put the proof of their labors.
"Hackers tend to use it just to post large bits of information to brag about what they've done," Matt Willis, vice president of Computer Forensic Services in Minnetonka, told Fox 9 News.
The information shared via Pastebin was quickly deleted, but it included the key to how the group got access to the servers.
"They didn't give Comcast a lot of notification before they published it publicly," Willis observed. "It looks like it was an intent to embarrass Comcast. They probably bragged even prior to putting it on PasteBin to their colleagues so they would have a chance to use the same vulnerability."
So far, Comcast hasn't publicly addressed the hackers' claims, but Willis suspects company officials are likely still working to figure out exactly how much information the group took, how many people were affected, and what the security vulnerability might be.
On Wednesday afternoon, Comcast released a short statement to Fox 9 News about the breach saying, "We have aggressively investigated this incident and have found no evidence to suggest any customer information was obtained."
Comcast representatives told Fox 9 News there is no reason to think the breach is anything like what happened to Target; however, they still refuse to confirm the hack was anything more than a claim. As it stands, personal privacy professionals urge Comcast customers change their passwords to be on the safe side.
