HEROIC Analysts Found the chipmunkbox.com Password Leak on Telegram

HEROIC analysts identified a combolist tied to chipmunkbox.com circulating on a Telegram channel, uploaded on 10-Jun-2026. The file contains 1,962 records pairing email addresses with plaintext passwords, along with related URLs, giving anyone who downloads it a ready-made list of working login credentials.

Why the chipmunkbox.com Combolist Is Dangerous

Because the passwords in this file are stored in plaintext rather than hashed or encrypted, anyone who gets a copy can immediately try each email and password pair on other websites without any extra work. If you used the same password anywhere else, an attacker does not need to guess or crack anything. They can simply copy and paste it in.

What Was Exposed in the chipmunkbox.com Leak

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Even a leak of a couple thousand records gives attackers usable material. Combolists are fed into automated tools that test the same email and password combination across banking sites, email providers, and social media platforms in a process known as credential stuffing. A single reused password can open the door to account takeover, identity theft, or financial fraud, especially if the exposed email address is also used to recover other accounts.

How Combolist Leaks Like This Happen

A combolist is a compiled text file of email or username and password pairs, often pulled together from older breaches, phishing pages, or malware infections and repackaged for resale or free distribution. Unlike a direct hack of one company's database, a combolist can blend data from many different sources, which is why the exact origin of each record is not always clear. In this case, the file was shared by a Telegram user, a common distribution method for combolists on the dark web.

Check If You Are Affected

HEROIC's free breach scanner searches a database of more than 400 billion leaked records to tell you instantly whether your information has appeared in this or any other breach, so you can change exposed passwords before someone else uses them.
