2,840 Records Exposed: luoyue.club Stealer Log Leak Found

In June 2026, HEROIC analysts identified a stealer log file uploaded to a Telegram channel by an anonymous user. The file contained 2,840 exposed records tied to luoyue.club accounts, dated June 21, 2026. Unlike a traditional corporate breach, this data was not stolen from luoyue.club's servers directly. It was harvested from individual devices already infected with information-stealing malware, then bundled and shared publicly on Telegram. The exposed records include email addresses, plaintext passwords, and the URLs each credential pair was used on.

Why This Is Dangerous

Because the passwords in this dataset were stored and shared in plaintext, anyone who downloads the file can use them immediately, with no cracking or decryption required. Paired with matching email addresses and the exact websites (URLs) those credentials unlock, attackers have a ready-made shortcut into whatever accounts these 2,840 people were logged into when their device was compromised.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of stolen credentials

Why This Matters

Stolen credentials like these fuel credential stuffing attacks, where automated tools test the same email and password combination across banking, email, and shopping sites, hoping victims reused their password. For the people in this 2,840-record leak, any account sharing that same password is now at risk of takeover, and any personal or financial details stored behind those logins could be exposed next.

How Stealer Logs Work

Stealer logs come from malware that quietly runs on an infected computer or phone, copying saved passwords, browser autofill data, and login sessions before sending everything back to whoever controls the malware. That operator then sells or, as in this case, freely distributes the harvested data on platforms like Telegram. Because the malware captures whatever the browser has saved, a single infected device can leak credentials for dozens of unrelated websites at once.

Check If You Are Affected

The safest move is to find out directly rather than guess. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, so you can see quickly whether your information turned up and take action before anyone else does.
