Inside the CRYPTON_LOGS Dump: How Malware Harvested 4,353 Passwords

HEROIC analysts identified a stealer log file, labeled CRYPTON_LOGS FREE, uploaded to a public Telegram channel on December 19, 2022. The file contained 4,353 records pulled from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts those credentials belong to.

Why the CRYPTON_LOGS Credentials Are Dangerous

The passwords in this file are stored in plaintext, so anyone who downloads it can use the credentials immediately with no cracking required. Because each password is listed alongside the exact URL it unlocks, an attacker can skip straight to logging in rather than guessing which site a stolen credential belongs to.

What Was Exposed in the CRYPTON_LOGS File

• Email addresses
• Plaintext passwords
• URLs of the accounts and services accessed

Why This Matters for the 4,353 Records Involved

Credentials this exposed are prime material for credential stuffing, where attackers test the same email and password combination across banking, email, and social media platforms. Anyone whose information appears in this log faces a real risk of account takeover, and if that password was reused elsewhere, the exposure extends into identity theft and financial fraud on other accounts too.

Inside How a Stealer Log Like CRYPTON_LOGS Gets Made

A stealer log is the direct output of infostealer malware, which infects a device through a phishing email or a malicious download and then quietly copies saved browser passwords, autofill data, and the web addresses tied to them. Rather than targeting a company's servers, this kind of malware works one infected device at a time, harvesting whatever credentials are stored locally. Once collected, the malware sends everything back to the operator running it, who in this case uploaded the finished log directly to a Telegram channel, giving anyone in that channel immediate access to all 4,353 records.

Check If Your Credentials Are in the CRYPTON_LOGS Leak

If you are unsure whether your email or password ended up in a stealer log like this one, it is worth checking now rather than after an account is compromised. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like CRYPTON_LOGS, so you know right away if a password needs to change.
