‘Ok Uploaded by a Telegram User’: 2,501 Passwords Leaked Since 2025

HEROIC analysts identified a combolist uploaded to a Telegram channel on August 10, 2025, containing 2,501 records of email addresses paired with plaintext passwords, along with associated login URLs. Unlike a breach tied to a single company, this file was compiled and shared by an anonymous Telegram user, meaning the credentials inside likely come from multiple sources stitched together into one list.

Why Plaintext Passwords Make This Dangerous

The passwords in this combolist were stored and shared in plaintext, meaning anyone who downloads the file can read them directly with no cracking or decryption required. Paired with an email address and a URL showing where the login works, this is a ready-made toolkit for an attacker to start logging into accounts immediately.

What Was Exposed in This Combolist

• Email addresses
• Plaintext passwords
• URLs linked to the accounts

Why This Matters for Reused Passwords

Most people reuse the same password, or a close variation of it, across several accounts. If any of the 2,501 credentials in this file match a password you use elsewhere, an attacker can attempt credential stuffing: automatically trying the same email and password combination across banking sites, email providers, and social media until one works. That single reused password can turn into a full account takeover, identity theft, or financial fraud.

How This Telegram Combolist Was Built

A combolist is a plain text file of email-and-password pairs, often gathered from older breaches, phishing pages, or malware logs and merged into one list for easy distribution. Telegram has become a common marketplace for this kind of file because channels are easy to set up, hard to fully shut down, and let sellers or hobbyists share stolen data with little friction. This particular file appears to have been assembled and posted by a single Telegram user rather than sourced from one identifiable company breach.

Check If Your Email Appears in This Leak

With 2,501 email and password pairs already circulating, the safest move is to find out directly whether your information is one of them. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, so you can see your exposure and change any reused passwords before someone else finds them first.
