One Telegram File. 870 Records. Alberta Health Logins Exposed.

One Telegram upload. One file. 870 exposed logins. HEROIC analysts identified a file titled "albertahealthservices.ca - 871 emails" uploaded to a Telegram channel on 10-Jun-2026, containing 870 confirmed records tied to the albertahealthservices.ca email domain. Each entry pairs an email address with a plaintext password and the URL of the site that login was used on.

Why This Is Dangerous

These are not patient medical records, but they are staff and system login credentials tied to a healthcare organization, and that distinction matters less than it might seem. Because the passwords are stored in plaintext, an attacker can use them immediately. A compromised healthcare employee email account can become a stepping stone into internal scheduling systems, communications, or other connected tools, on top of whatever personal risk the account holder faces from password reuse elsewhere.

What Was Exposed in the albertahealthservices.ca File

• Email addresses (albertahealthservices.ca accounts)
• Plaintext passwords
• URLs of the sites where the credentials were used

Why This Matters for These Account Holders

With 870 confirmed email and password pairs circulating, attackers can manually test each one for credential stuffing against personal banking, email, and social media accounts, hoping a password was reused outside of work systems. A successful match leads to account takeover, and from there, identity theft or financial fraud becomes a real risk for the individual, regardless of the healthcare context their work email is tied to.

How a Leak Like This One Gets Compiled

Files sorted by an organization's email domain, like albertahealthservices.ca, are typically the output of stealer log malware, which infects a device and silently copies saved usernames and passwords along with the sites they were used on. Once collected, this stolen data gets organized by domain and shared or sold through Telegram channels, letting buyers target employees of a specific organization rather than a broad, unsorted mix of accounts.

Check If You Are Affected

If you have an albertahealthservices.ca email account, it is worth checking whether your information appears in this exposure. HEROIC's free breach scanner searches more than 400 billion leaked records to quickly show you if your data has been compromised and what to do next.
