Dark Web Find: Comcast Stealer Log Exposes 71,533 Accounts

In June 2026, HEROIC dark web intelligence analysts flagged a stealer log labeled "Comcast" circulating on a Telegram channel used to distribute malware harvested credentials. The file contained 71,533 records, each pairing a login URL, an email address, and a plaintext password tied to Comcast accounts.

What HEROIC's Dark Web Monitoring Found

HEROIC's monitoring systems track Telegram channels and dark web forums where stealer logs are shared, and this file stood out for its size and its focus on a single provider. A log this large, tied specifically to Comcast, suggests the underlying malware infections were widespread enough to sweep up tens of thousands of subscribers over a short period.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• Associated Login URLs

Why This Matters

With 71,533 ready-to-use credential pairs in circulation, this log is well suited to automated credential stuffing against Comcast's customer portal and any other site where a victim reused the same password, opening the door to account takeover, billing fraud, and identity theft.

How Stealer Logs Work

Stealer logs are generated by malware that infects a device, harvests saved browser credentials, and transmits them to the attacker automatically. Once collected, criminals sort large logs like this Comcast file by provider before listing them on Telegram, where dark web buyers pay a premium for logs tied to a single well known service.
