Emails, Plaintext Passwords, and URLs Leak in the CryptogoL12 File

A file labeled simply CryptogoL12, with no batch number attached, surfaced on Telegram on August 25, 2026, containing 4,648 email and plaintext password pairs, each mapped to the exact site it unlocks. HEROIC analysts catalogued every record in it. The only way to know if yours is among them is to scan your email for free.

Why This File Stands Out From the Rest of the Series

Unlike the numbered CryptogoL12 batches circulating alongside it, this file carries no batch number of its own, suggesting it was an early piece released before later batches were split out and numbered. Size aside, its contents work exactly the same way as every other slice: a usable login matched to the page it opens.

What's Inside the CryptogoL12 File

• Email Addresses: point directly to a live inbox.
• Plaintext Password: stored in readable form, ready to use immediately.
• URLs: identify exactly which site or app each login belongs to.

Why a Smaller File Still Causes Real Damage

4,648 is a modest count next to some of the larger CryptogoL12 batches, but every record here is just as complete. A single reused password found in this file can lead straight to account takeover, and from there to further fraud on any other service that shares the same login.

How Malware Produces a File Like This

Stealer malware sitting on an infected device quietly collects saved browser logins, including the site, the account name, and the password stored for it. Everything pulled from one machine is packaged into a single file like CryptogoL12 and then sold or shared, which explains why even a smaller file can still hold thousands of working logins.

Check Whether CryptogoL12 Exposed Your Email

Use the link below to scan your email rather than assume you are safe because the file is smaller than others in the series. If your address appears, clean the affected device before changing any passwords, and give every account, personal or work, its own unique password from that point forward.
