Ok Uploaded by a Telegram User: 630 Login Credentials Exposed

HEROIC analysts identified a small combolist file circulating on Telegram, uploaded on 15 June 2025. The file contained 630 records pairing email addresses with plaintext passwords, along with associated URLs tied to the accounts. While the volume is modest compared to major breaches, every record in a combolist like this is a working set of login credentials that someone can use right now.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who gets hold of it can read and use them immediately, no cracking or decryption required. Combined with the associated URLs, an attacker has a ready-made map of which site each email and password combination unlocks, making it trivial to log in as the victim.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

Most people reuse the same password across multiple accounts. Once a plaintext password is exposed alongside an email address, attackers run it against banking sites, email providers, and social media through a process called credential stuffing. If any of those attempts succeed, the result can be account takeover, identity theft, or direct financial fraud, all stemming from a single reused password.

How Combolist Leaks Work

A combolist is simply a text file of email and password pairs, compiled from older breaches, phishing campaigns, or malware infections and then repackaged for resale or free distribution on platforms like Telegram. Unlike a hacked database, a combolist does not require breaking into a company's systems. It is built by collecting already-stolen credentials from multiple sources and bundling them together, which is why these files can appear with little warning and limited detail about where the data originally came from.

Check If You Are Affected

If you think your email or password may be part of this or any other leaked dataset, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records. It takes seconds to run and gives you a clear answer, along with guidance on what to change if you are exposed.
