HEROIC Analysts Find 3,566 Crosslink.net Passwords Leaked

In June 2026, HEROIC's dark web analysts identified a stealer log uploaded to Telegram on 10-Jun-2026 containing 3,566 records tied to crosslink.net. Researchers found the file held email addresses, plaintext passwords, and the URLs of the sites those credentials were captured on, data consistent with malware that had been quietly harvesting saved logins from an infected device.

Why This Crosslink.net Stealer Log Leak Is Dangerous

Analysts note that each record links a working email and password directly to the exact site it unlocks, meaning anyone who obtains the file can attempt to log in immediately. With 3,566 of these pairs available, an attacker has a substantial, ready-to-use list of accounts to try.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were used on

Why This Matters

Because the passwords were captured in plaintext, no decryption is needed before they can be used. Researchers point out that if any of the 3,566 affected people reused their crosslink.net password elsewhere, those accounts are also at risk through credential stuffing, where attackers automatically test the same login pairs against other websites and services.

How Stealer Logs Work

Stealer logs are generated by infostealer malware, which commonly spreads through fake downloads, pirated software, or phishing attachments. Once it infects a device, it silently copies saved browser passwords and login data, then sends everything back to the attacker. That stolen data is compiled into a file and shared or sold, in this case uploaded directly to a Telegram channel.

Check If You Are Affected

If you use a crosslink.net email address or have logged into an account with it, it is worth checking whether your details appear in this log. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records in seconds, so you can find out right away and change any exposed passwords.
