CRYPTON_LOGS 301PCS October 2025 Contains Exactly 6,021 Email and Password Pairs

On October 31, 2025, HEROIC analysts catalogued a stealer log dataset uploaded to a public Telegram channel under the name CRYPTON_LOGS 301PCS. This particular batch contained exactly 6,021 records, each representing credentials harvested from an infected endpoint device. The exposed data included email addresses, plaintext passwords, and URLs identifying the specific online services and API endpoints the stolen credentials were used with. The October 2025 timestamp makes this a recent addition to the ongoing CRYPTON_LOGS series of Telegram-distributed stealer log packages.

Why This Is Dangerous

The danger with any stealer log dump that includes plaintext passwords is the complete removal of the cracking step that typically slows attackers down. Every one of the 6,021 records in this dataset is immediately usable. Attackers who accessed this Telegram channel walked away with a ready-made list of email addresses, the passwords that go with them, and the specific services those passwords unlock. That last detail -- the URLs -- is what separates stealer logs from generic credential dumps. The attacker does not need to guess where to try the passwords. The malware already recorded exactly where they came from.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (service login pages and API endpoints)

Why This Matters

Stealer log batches like this October 2025 CRYPTON_LOGS 301PCS release are raw material for credential stuffing campaigns. Attackers take these verified pairs and run them through automation tools against financial institutions, email providers, e-commerce platforms, and corporate remote access portals. Even a low success rate across 6,021 accounts translates into dozens of compromised profiles, which can then be exploited for identity theft, fraudulent purchases, unauthorized bank transfers, and in some cases, a foothold into corporate networks if any of the affected accounts belonged to business users. The recency of this dump makes it particulerly high risk -- many of these passwords may still be active.

How Stealer Logs Work

A stealer log originates from infostealer malware installed silently on a victim's device. The malware typically arrives through a phishing email, a malicious advert that triggers a drive-by download, or software bundled with a cracked application. Once active, it scrapes the browser's saved password store and any form autofill data, recording the exact URL and API host tied to each set of credentials, then packages everything into a structured log file for exfiltration to the attacker's server. These logs are then sorted, deduplicated, and distributed in batches -- the 301PCS in the name of this dataset likely refers to the batch number or package count within the CRYPTON series. The Telegram distribution method favored by this operator allows for fast, pseudonymous sharing with a large audience of buyers and downloaders.

Check If You Are Affected

If your email address appeared in the CRYPTON_LOGS 301PCS dataset from October 2025, your login credentials for one or more online services may be in the hands of attackers right now. HEROIC's breach monitoring database holds more than 400 billion records from thousands of data incidents, includng this stealer log series. Visit heroic.com to search your email address and see whether your data was captured in this or any related dump. If it was, change your passwords immediately and enable two-factor authentication on every account that supports it.
