‘500 Pcs Private’ Stealer Log Exposed 7,274 Logins From Infected PCs

HEROIC analysts found a stealer log labeled "500 Pcs Private" uploaded to a Telegram channel on July 30, 2026. The file contains 7,274 records pulled from roughly 500 malware-infected computers, including saved login endpoints, email addresses, API hosts, and plaintext passwords harvested directly from victims' devices.

Why Data Pulled From Infected PCs Is So Dangerous

Unlike a leak from a single company's database, a stealer log comes straight from the victim's own computer. The malware that infected these roughly 500 machines copied saved browser passwords, login pages, and account details exactly as the person typed them, in plaintext. That means an attacker does not need to guess or crack anything. They can log in using the same working credentials the real owner used.

What Was Exposed in the 500 Pcs Private Log

• Email addresses
• Plaintext passwords
• Login endpoint URLs
• API host addresses

Why This Matters for Everyone in the File

If one of your accounts is among the 7,274 records here, an attacker already has a working email, password, and the exact URL where that login is used. That combination enables direct account takeover, and if the same password is reused elsewhere, it opens the door to credential stuffing across other sites, identity theft, and financial fraud.

How Stealer Logs Like This One Are Made

Stealer logs are created by infostealer malware that infects a computer, often through a fake download, cracked software, or malicious email attachment, and then quietly copies every saved password, cookie, and login stored in the browser. Once the malware finishes collecting data, the results are packaged into a log file and sold or shared, in this case labeled to indicate it came from around 500 infected machines and was being offered as a private sale on Telegram.

Check If Your Login Is in This Stealer Log

Because stealer logs hand attackers a live, working password rather than an old or hashed one, checking your exposure quickly matters. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can find out fast and change any exposed passwords before they are used.
