HEROIC Finds Rust.net Data on Telegram: 640 Passwords Leaked

HEROIC Analysts Spot Rust.net Stealer Log on Telegram

In June 2026, HEROIC's threat intelligence team was monitoring Telegram channels used to trade stolen data when they came across a stealer log file exposing 640 records tied to rust.net. The file surfaced on 10 June 2026 and contains email addresses, plaintext passwords, and the URLs those credentials were entered on, all pulled directly from infected devices.

Why This Stealer Log Is Dangerous

Because the passwords in this dump are stored in plaintext and matched to specific login URLs, an attacker does not need to crack or guess anything. They can simply take the email, password, and web address together and log straight into the account it belongs to.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs associated with the logins

Why This Matters

Plaintext passwords tied to login URLs are exactly the kind of data used in credential stuffing and account takeover. If any of the 640 people in this dump reused their password on other accounts, such as email, banking, or shopping sites, an attacker could use this leaked password to break into those accounts too.

How Stealer Logs Work

Stealer logs come from infostealer malware, which infects a device, often through a phishing link or fake download, and quietly copies everything saved in the browser: usernames, passwords, cookies, and autofill data. Criminals then bundle that stolen information into a log file and sell or trade it on Telegram channels and dark web forums, exactly where HEROIC analysts found this rust.net data.

Check If You Are Affected
