Inside the CryptogoL12 5 File: 15,305 Logins Uncovered

HEROIC analysts discovered a stealer log called CryptogoL12 5 circulating on Telegram, dated August 26, 2026, with 15,305 records pairing email addresses, plaintext passwords, and the URLs those logins unlock. The file was flagged shortly after it began circulating. Scanning your email is the only way to confirm whether you are one of the 15,305 people listed.

What HEROIC Analysts Found Inside the File

Every record in CryptogoL12 5 follows the same pattern: an email, a password sitting in plain readable text, and the address of the site that password unlocked. Because the file only surfaced recently, the credentials inside it are likely still active, which narrows the window account owners have to react before someone tries them.

What Was Exposed

• Email Addresses: pinpoints the exact account each stolen password belongs to.
• Plaintext Password: left in fully readable form, so it works the moment it is copied out of the file.
• URLs: records which login page the credential pair was actually captured on.

Why This Matters

Because the password and the matching site are both included, there's no extra step between finding a record and trying it. The bigger danger shows up if that same password was reused anywhere else, since a working combination like this one can be tested against other popular logins just as easily.

How This Breach Type Works

CryptogoL12 5 is a stealer log, which means the data was never taken from a company's servers. Malware already sitting on an infected device collected saved browser credentials and the sites tied to them, then sent that haul back to whoever controlled the malware. That is why one file can hold logins for completely unrelated services.

Were You Counted Among the CryptogoL12 5 Records?

Check first with the scan your email tool above. Since the source device was infected, assume it may still be compromised and clean or reset it before changing anything. Once it's safe, update the exposed password from a separate device, along with any other account where you used that same password, whether it's a personal login or one you use for work.
