1,317 Email and Password Pairs Surface in 1.3K-Combo Dark Web List

HEROIC analysts reviewed a dark web combolist named 1.3K-Combo that surfaced on Telegram on 20 January 2026. Inside the file sit 1,317 records, each pairing an email address with a plaintext password and the web address where that login worked. The passwords are stored in plain text, meaning anyone who downloads the file can read and reuse them immediately. If you reuse passwords across accounts, it is worth taking two minutes to scan your email and check whether you show up in this batch.

What Someone Can Do With a Combolist Like This

A combolist is built specifically for automated abuse. Criminals load files like 1.3K-Combo into credential stuffing tools that try each email and password pair against banking portals, email providers, streaming services and workplace logins. Because the passwords here are already in readable form, no cracking or decryption step is needed before an attacker can start testing them.

The Login Data Exposed in 1.3K-Combo

• Email Addresses
• Plaintext Password
• URLs

The Risk to Anyone on This List

Anyone whose email and password appear in 1.3K-Combo faces a real chance of account takeover on any site where that same password is still active. The included URLs point attackers straight at the service each credential was captured for, cutting the guesswork out of targeting. From there, a hijacked inbox can be used to reset passwords on connected accounts, and reused logins can open the door to financial platforms or workplace tools tied to the same email.

How Combolists Like This Take Shape

Combolists are usually stitched together from older breaches, phishing hauls and malware logs, then cleaned up and repackaged so every line is a usable email and password pair. Sellers and Telegram channels circulate these compiled files because they save buyers the work of sorting raw data themselves. Once a list like this starts circulating, it tends to get copied and redistributed, which means exposure does not end when the original post disappears.

Check Your Exposure Before Attackers Do

Do not wait to find out the hard way. Scan your email to see if your address turns up in 1.3K-Combo or any other dataset HEROIC has indexed. If you get a match, change that password everywhere it was reused and turn on two-factor authentication. This is worth doing for personal inboxes and work email alike, since a single reused password can bridge the two.
