313 Records Exposed in “300 .CA Mail Access 1” Telegram Leak

In June 2026, HEROIC analysts identified a stealer log file uploaded to Telegram under the name "300 .CA Mail Access 1," containing 313 records of Canadian email account logins. The file included email addresses, plaintext passwords, and the URLs of the login pages those credentials were used on, data pulled directly from infected devices rather than a breach of any email provider's own systems.

Why This Is Dangerous

The label ".CA Mail Access" suggests this file was specifically compiled to target Canadian email accounts, giving whoever distributed it a focused list rather than a random mix of logins. Because the 313 passwords are stored in plaintext, no cracking is required before they can be used, and the matching login URL for each entry means an attacker can go straight to the correct sign-in page and attempt access immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Email access is often the master key to a person's other accounts, since it is commonly used to receive password reset links for banking, shopping, and social media. A leak this size may look small, but each of the 313 affected users faces a real risk of account takeover if their credentials still work, and an even greater risk if the same password was reused elsewhere, since that opens the door to credential stuffing across unrelated services.

How Stealer Logs Work

Stealer logs are produced by malware that infects a victim's computer, often through a pirated download, a fake software update, or a malicious attachment. Once active, the malware quietly copies saved passwords, autofill data, and login sessions straight out of the victim's browser, then sends everything back to whoever is running the malware. That data is organized into files like this one, sometimes grouped by email provider or region as this "CA Mail Access" file appears to be, and then shared or sold through Telegram channels and dark web forums.

Check If You Are Affected

If you use a Canadian email provider or reuse passwords across accounts, it is worth checking whether your information appears in this leak or any other. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, so you can see your exposure and secure your accounts before someone else does.
