What Is a Stealer Log? CRYPTON_LOGS Leak Exposes 13,841

HEROIC analysts identified a stealer log file called CRYPTON_LOGS 301PCS, uploaded to a public Telegram channel on April 6, 2025. The file contained 13,841 exposed records, including email addresses, plaintext passwords, and the URLs of the accounts those credentials belong to, all harvested directly from infected devices.

Why This Is Dangerous

Because the passwords in this file are stored in plaintext and matched to the exact login URL, anyone who downloads it can start using the credentials immediately. There is no cracking or guesswork involved, just a ready-made list of working logins.

What Was Exposed

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

Why This Matters

Anyone who reused a leaked password on another site is at risk of credential stuffing attacks and account takeover. Combined with the linked email addresses, the data also gives attackers a foothold for identity theft and financial fraud against victims who may have no idea their information is exposed.

What Is a Stealer Log

A stealer log is the direct output of infostealer malware, a type of software built to infect a device, quietly scan the browser for saved passwords and autofill data, then package everything it finds into a single file. That file, tied to one infected machine, is what criminals call a log. They typically infect victims through phishing links, cracked software, or fake installers, then collect thousands of these logs and sell or upload them in bulk, exactly as happened with CRYPTON_LOGS 301PCS.
