Did the CRYPTON_LOGS Breach Expose Your Credentials?

What Happened in the CRYPTON_LOGS 301PCS Breach

On 24-Oct-2024, an anonymous Telegram user uploaded CRYPTON_LOGS 301PCS to a public channel. It is a sibling to the earlier CRYPTON_LOGS 299PCS drop and was posted in the same wave. The file shows up in dark web monitoring as a stealer log, meaning every record came directly from an infected endpoint rather than a breached service database.

Scope and Scale of the Exposure

The archive contains 4,776 records. Each entry pairs an email address with a plaintext password and the URL where that login is known to work. With no hashing in the way, attackers can use the file immediately, feeding it into credential stuffing tools or targeting each URL manually. That makes per-record risk extremely high.

Did the Breach Expose Your Credentials

If you saved browser credentials on a device that may have been infected by a stealer in the weeks before 24-Oct-2024, you could be in the 301PCS file. Because the drop blends credentials from many targets, consumer, enterprise, and financial logins are all represented. Treat any password reused across services as compromised.

How the Data Was Harvested

The file format matches output from popular infostealers including RedLine, Lumma, Vidar, and StealC. These tools reach victims through cracked software, malicious advertising, phishing attachments, and fake browser or driver updates. Once running, they quietly export saved credentials, cookies, and autofill data, which operators then package into Telegram-ready bundles.

Why the 301PCS Drop Matters

Sequential drops like CRYPTON_LOGS 299PCS and 301PCS let operators keep a steady supply of fresh credentials flowing to buyers without any single file being so large that it draws outsized scrutiny. For defenders, this pattern means that even users who rotated after the earlier drop may still find themselves in the follow-on.

Recommended Next Steps

Change passwords on every account where you reuse a password stored in your browser, starting with email, banking, and crypto accounts. Turn on multi-factor authentication for every sensitive service, prefer authenticator apps or hardware keys over SMS, and run a full antivirus scan on devices where credentials were saved. Use HEROIC dark web monitoring to confirm whether your email appears in the CRYPTON_LOGS 301PCS drop.
