Search Your Email: pcmail.com Leak Exposed 782 Passwords

In June 2026, HEROIC analysts found a stealer log tied to pcmail.com uploaded to Telegram by a threat actor. The file contained 782 records made up of email addresses, plaintext passwords, and the URLs those credentials were used on.

Why This pcmail.com Stealer Log Is Dangerous

Small leaks like this one are often overlooked, but the risk is just as real. The passwords are stored in plaintext and matched to the exact web address each one unlocks, so an attacker does not need to decode or guess anything before attempting to log in.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

Because each password is matched to its exact login page, attackers can move straight to account takeover on the 782 accounts in this log. If any of these passwords were reused on other services, such as email, banking, or shopping accounts, credential stuffing tools let attackers test the same password across many unrelated sites, spreading the damage beyond this single leak.

How Stealer Logs Work

Stealer logs come from malware that infects a device and quietly copies saved browser passwords, autofill entries, and the web addresses tied to them, then sends everything back to the attacker. Because the theft happens on the victim's own computer rather than a hacked company server, the stolen credentials are often still valid when the log surfaces on Telegram.

Check If You Are Affected

Search your email address on HEROIC's free breach scanner to see if it turned up in this stealer log or another one like it. The scanner checks a database of more than 400 billion leaked records, so you can find out quickly and change any exposed passwords.
