How Stealer Malware Behind CRYPTON_LOGS 301PCS Exposed 8,906 Logins

HEROIC analysts found a stealer log file, labeled CRYPTON_LOGS 301PCS, uploaded to a public Telegram channel on October 27, 2025. The file exposes 8,906 records, each containing an email address, a plaintext password, and the URL of the service the credentials belong to.

Why This Is Dangerous

Because the passwords in this file were stored and leaked in plaintext, they are immediately usable. No decryption or password cracking stands between an attacker and a working login. If any of these 8,906 credentials were reused on another site, that account can be accessed the same way.

What Was Exposed in the CRYPTON_LOGS 301PCS Leak

• Email addresses used to log into affected accounts
• Plaintext passwords, stored and leaked with no encryption
• URLs and API host addresses showing which services the credentials unlock

Why This Matters

Even a smaller leak like this one feeds directly into credential stuffing, where attackers automate login attempts across many sites using stolen email and password combinations. With 8,906 confirmed working pairs, an attacker has a ready made list for automated account takeover attempts, which can lead to financial fraud, hijacked email accounts, and identity theft for anyone whose password was reused.

How a Stealer Log Like CRYPTON_LOGS 301PCS Gets Made

CRYPTON_LOGS 301PCS is a stealer log, the kind of file produced by information-stealing malware that infects a device and silently exports saved credentials, cookies, and browsing data to the attacker. Malware like this is often distributed through fake downloads, cracked software, or phishing links, and once it runs, it can harvest credentials from every browser and app on the machine. The resulting log is then packaged, as this one was, and shared on Telegram, where it becomes ready made ammunition for credential stuffing and account takeover.
