Anyone notice the 590K emails/plaintext passwords allegedly from Comcast being sold? pic.twitter.com/jbASQP0E2Y— flanvel (@flanvel) November 7, 2015
It’s not clear where the data comes from, but Comcast insists that the source is not a breach of the communications giant’s own security. The fact that many of the accounts appear to be out of date or fake lends credence to that assertion.
It’s possible for hackers to gain access to masses of information like this without breaching Comcast’s own systems. Instead, they could breach wide swaths of customer devices or other networks with the information.
Comcast customers can also manually reset their password, something all users should do on a regular basis as a security measure.
