Chuck Leaver – Data Exfiltration And Shared Hacks Putting Comcast Customers At Risk

The Customers Of Comcast Are Victims Of Data Exfiltration and Shared Hacks Via Other Businesses

The private details of around 200,000 Comcast customers was jeopardized on November 5th 2015. Comcast was forced to make this statement when it came to light that a list of 590,000 Comcast client e-mails and passwords could be bought on the dark web for a mere $1,000. Comcast argues that there was no security breach to their network however rather it was via past, shared hacks from other businesses. Comcast even more claims that only 200,000 of these 590,000 clients really still exist in their system.

Less than two months previously, Comcast had already been slapped with a $22 million fine over its accidental publishing of almost 75,000 customers’ individual details. Rather paradoxically, these clients had actually specifically paid Comcast for “unlisted voice-over-IP,” a line item on the Comcast bill that stipulated that each client’s information would be kept confidential.

Comcast set up a mass-reset of 200,000 consumer passwords, who may have accessed these accounts prior to the list was put up for sale. While an easy password reset by Comcast will to some extent safeguard these accounts going forward, this doesn’t do anything to protect those consumers who may have recycled the same email and password mix on banking and credit card logins. If the client accounts were accessed prior to being disclosed it is definitely possible that other personal details – such as automatic payment information and home address – were currently obtained.

The bottom line is: Assuming Comcast wasn’t hacked directly, they were the victim of various other hacks that contained data connected to their customers. Detection and Response solutions like Ziften can prevent mass data exfiltration and typically reduce damage done when these inevitable attacks take place.
