compusmart.ab.ca Combolist Leaked 3,657 Email and Password Pairs

What HEROIC Analysts Found

In June 2026, HEROIC's threat intelligence team identified a combolist tied to compusmart.ab.ca after it was uploaded to Telegram by an individual user. The file contained 3,657 records pairing email addresses with plaintext passwords, along with the account URLs they were used with.

Why This Is Dangerous

Because these passwords were stored and shared in plaintext, anyone who downloads this file can read the password exactly as it was typed, with no cracking involved. If you reused that password on any other site, an attacker already has everything needed to log in.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

A leak of this size gives criminals a sizable batch of working credentials to work with. Attackers feed lists like this into automated tools that test the same email and password pair across banking sites, email providers, and social media platforms, a technique called credential stuffing. If you have reused this password anywhere, it can lead to account takeover, identity theft, or financial fraud.

How Combolists Work

A combolist pairs a username or email with a password, usually one pair per line in a plain text file. These lists are often stitched together from smaller breaches, stealer malware infections, or scraped login pages, then shared or sold through Telegram channels and dark web forums. Because they require no hacking skill to use, combolists remain one of the simplest tools behind everyday account takeovers.

Check If You Are Affected

HEROIC's free breach scanner checks your email address against a database of more than 400 billion breached records, including combolists like this one. If your information turns up, change that password right away and anywhere else you have used it.
