Check Your Inbox: 25 AUGUST-1600PCS Leak Exposed 5,563 Logins

HEROIC analysts also tracked a related stealer log, 25 AUGUST-1600PCS, uploaded to the same Telegram channel on 25-Aug-2026. It lists 5,563 records pairing email addresses with plaintext passwords and the login URLs they belong to. Nothing in the file is encrypted, so the credentials work as soon as someone opens it, making it worth checking your own inbox against this leak.

A Smaller File, the Same Level of Risk

This dump is smaller than some others HEROIC has tracked, but size has little to do with danger here. Each record still gives an attacker a complete, working login: an email, its password, and the exact page to use it on. A file this size is just as easy to run through automated login tools as a much larger one.

The Login Data Exposed in 25 AUGUST-1600PCS

• Email Addresses
• Plaintext Password
• URLs

How This Turns Into a Bigger Problem

Beyond the accounts named in the file, the real exposure comes from repeated passwords. Attackers routinely test leaked email and password pairs against banking portals, email providers, and workplace logins that were never part of the original breach. One reused password can carry the damage far past this single file.

Where These Credentials Usually Come From

Dumps like this one are typically produced by info-stealer malware sitting quietly on an infected device. It reads the passwords and form data a browser has saved, organizes everything by machine, and ships the results back to whoever controls it. From there, the file gets labeled, counted, and passed along through channels like this.

Confirm You Were Not Caught Up in This

Scan your email to find out if it shows up in this file or elsewhere in HEROIC's records. If it does, update that password now, and do the same anywhere else you have used it. The same advice holds whether the account in question is personal or work related.
