The processed_20250522_103627 Leak: 191,395 Logins Exposed

HEROIC analysts found a stealer log file named "processed_20250522_103627" that a Telegram user uploaded on May 22, 2025. The file contained 191,395 records tied to United States based accounts, including email addresses, plaintext passwords, and the URLs of the login pages those credentials belonged to.

Why This Is Dangerous

At nearly 200,000 records, this is one of the larger stealer log dumps to surface recently, and every password inside it is stored in plaintext, meaning there is no encryption standing between an attacker and a working login. Paired with the exact URL each credential unlocks, anyone who obtains this file can immediately identify which service to target and attempt to log in with no guessing involved.

What Was Exposed in the processed_20250522_103627 Leak

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

Why This Matters for the 191,395 Affected Accounts

An email, password, and login URL bundled together gives an attacker everything needed to attempt account takeover immediately, with no guesswork required. If any of the 191,395 people in this file reused their password elsewhere, the same combination can be tested against banking, email, and shopping accounts within minutes through automated credential stuffing tools. From there, the risk expands quickly into identity theft and financial fraud, since a compromised email account is often the key to resetting passwords on everything else tied to it.

How a Stealer Log of This Size Comes Together

A stealer log is the output of malware that quietly infects a device and harvests whatever login data it can find, typically credentials saved in a browser, autofill entries, and active session data. The malware reports back to the attacker, who compiles the results from many infected machines into a single dated file, which explains how a dump of this scale, nearly 200,000 records, comes together. These files are then circulated through Telegram channels and dark web forums. Because the theft happens on the victim's own device rather than through a breach of a company's servers, a single stealer log can expose credentials for dozens of unrelated sites at once.

Check If You Are Affected

If you are based in the United States, or think your credentials could have been swept up in a stealer log campaign around late May 2025, checking your exposure now is worth doing. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer log dumps like this one, to tell you whether your email address has surfaced in a known breach. If it has, change the affected password immediately, along with any other account where you reused it.
