How a Telegram Upload Turned Into the pris.bc.ca 849-Account Leak

HEROIC analysts identified a combolist labeled "pris.bc.ca - 849 emails" that was uploaded to a Telegram channel on 10 June 2026. The file contains 849 records made up of email addresses, plaintext passwords, and the login URLs those credentials belong to.

Why This Is Dangerous

Every entry in this file pairs a working email address with a plaintext password and the exact web address it logs into. That means an attacker does not need to crack or guess anything, they can simply pick up the file and start testing accounts right away.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs for the associated accounts

Why This Matters

Anyone whose email appears in this file is at risk of account takeover, especially if the same password is reused on other sites. Attackers feed combolists like this one into automated tools that try each pair against email providers, banking sites, and social media, a technique known as credential stuffing. A single reused password can open the door to several accounts at once.

How Combolists Work

A combolist like this one is typically built by pulling email and password pairs from older leaks and stealer logs and combining them into a single file, often organized around a shared domain or theme. Once assembled, the file gets uploaded and shared in Telegram channels, where other users pick it up and test the credentials at scale. It is a low-effort, low-cost way for criminals to turn old scattered leaks into a usable attack list.
