The noreplylinkedin.com Leak: 403 Email and Password Pairs Exposed

HEROIC analysts identified a combolist uploaded to Telegram on 19-Feb-2026 containing 403 records tied to noreplylinkedin.com. The file included email addresses, plaintext passwords, and associated URLs, the kind of ready-to-use login data attackers plug straight into automated tools.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who downloads it can immediately test the email and password pairs against other websites. There is no cracking or decryption required. The credentials are usable the moment they are copied out of the file.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Even a small combolist like this one carries real risk. If any of these 403 people reused their password on another account, whether email, banking, or social media, that account is now exposed to credential stuffing, where bots automatically test leaked logins across hundreds of sites in seconds. Attackers do not need every record to be valuable. They just need a handful of reused passwords to pull off an account takeover or identity theft.

How This Combolist Was Built

A combolist is a compiled text file of username or email and password pairs, gathered from multiple sources like older breaches, phishing kits, or stealer malware, then bundled together and traded on Telegram channels and dark web forums. Unlike a single hacked database, a combolist does not necessarily trace back to one company being breached. It is often assembled by threat actors from scraps of previously leaked data or freshly harvested credentials, then reshared to make automated login attacks easier for other criminals to run.

Check If You Are Affected

The safest step is to check whether your email address turns up in this combolist or in any of the other breaches HEROIC has indexed. HEROIC's free breach scanner searches a database of more than 400 billion exposed records and tells you in seconds if your information has been compromised. If you find a match, changing that password anywhere else you have reused it should be your next move.
