Comcast

A BlackMarket on the dark web was offering about 590,000 Comcast email addresses and passwords for sale.

The seller presented a list of 112 accounts asking for $300 USD for 100,000 accounts, and the complete list of 590,000 accounts sells for $1,000 USD as evidence of the reliability of the Comcast data.

Approximately 200,000 out of the 590,000 records that were being sold on the illicit market were still active, according to Comcast, which was in possession of the list and had been examining the exposed information.

The systems of Comcast have not been penetrated, according to the company's security staff, and each subscriber who reports unusual behaviour on his account will be contacted individually to address the problem.
