One File Labeled ‘Valid’: 208 Working Logins in Plaintext

HEROIC analysts identified a combolist file labeled "valid" uploaded to Telegram on 13 March 2026. The file contained 208 records pairing email addresses with plaintext passwords, along with associated URLs tied to the accounts. The label suggests the uploader claims these credentials have been checked and confirmed to work, making the file more immediately useful to anyone who obtains it.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, no cracking or technical effort is required to use them. Anyone who obtains the file can read each email and password pair directly and try it against the site it belongs to, or against other accounts where the same password might be reused.

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 credential stuffing. If any of those attempts succeed, the result can be account takeover, identity theft, or direct financial fraud, even from a small dataset like this one.

How Combolist Leaks Work

A combolist is a compiled text file of email and password pairs gathered from earlier breaches, phishing campaigns, or malware infections, then repackaged and shared on platforms like Telegram, sometimes labeled "valid" to signal the credentials have been tested. Building one does not require hacking a company directly. 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.
