Passwords Leaked: Canada Uploaded by a Telegram User Should Worry You

HEROIC analysts uncovered a combolist file posted to Telegram in August 2026 containing 413,649 records tied to an entry labeled "Canada uploaded by a Telegram User." Each record pairs an email address with a plaintext password, and many entries also list the URL of the site the login was originally used on.

Why This Is Dangerous

Because the passwords in this file are left in plaintext, an attacker does not need to crack, decrypt, or guess anything before trying a login. Add in the URLs included with each record, and a criminal can go directly to the correct site and attempt to sign in immediately, no extra research required.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to the original accounts

Why This Matters

If you reuse a password across more than one account, a single leaked credential can unlock several of your accounts at once. Attackers routinely take email and password pairs from files like this one and test them against banking sites, email providers, and online stores in what is known as credential stuffing. That can quickly escalate into account takeover, identity theft, or direct financial fraud.

How a Combolist Leak Works

A combolist is a plain text file of login credentials, typically formatted as email:password, often pulled together from several smaller breaches and stealer logs before being posted to a channel like this. Because the format is so simple, almost no technical skill is needed to use it. Automated tools can run a combolist against hundreds of login pages at once, which is why files like this spread quickly once they surface online.

Check If You Are Affected

Rather than wonder whether your email or an old password shows up in a leak like this one, you can check directly. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including combolists like this, so you can find out fast and change any password you are still reusing.
