IN 22.3 2 Combolist Leak: 18,512 Passwords Exposed to Attackers

A Combolist Tied to "IN 22.3 2" Surfaces on Telegram

HEROIC analysts identified a combolist, uploaded by a Telegram user and tracked internally as "in 22.3 2," dated 24 April 2023. The file contains 18,512 records pairing email addresses with plaintext passwords, alongside associated URLs, making it a ready-made toolkit for automated account takeover attempts.

Why This Is Dangerous

Because the passwords in this combolist are stored in plaintext, anyone who obtains the file can log directly into an account without cracking or decrypting anything first. Paired with the leaked URLs, an attacker can automatically match each email and password combination to the exact website it was used on, making large-scale credential stuffing fast and low effort.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each credential pair

Why This Matters

Combolists like this one are the raw fuel behind credential stuffing campaigns. Because so many people reuse the same email and password across multiple sites, a single exposed login can unlock email, banking, shopping, and social media accounts all at once. That kind of access opens the door to identity theft and financial fraud far beyond the original site where the credentials were collected.

How Combolists Work

A combolist is simply a compiled text file of credential pairs, typically email and password combinations pulled together from older breaches, malware logs, or manual collection, then repackaged for resale or free distribution, often on platforms like Telegram. Criminals load combolists into automated tools that test each pair against dozens of popular websites in seconds, flagging every login that still works.

Check If You Are Affected

With 18,512 records now circulating, checking your own exposure only takes a moment. HEROIC's free breach scanner searches more than 400 billion leaked records, including combolists like this one, so you can find out immediately whether your email address has been exposed and take action before someone else uses it.
