The Psi.ch Stealer Log Contains More Passwords Than a Small Village

HEROIC analysts found a stealer log dataset tied to psi.ch that was uploaded to a Telegram channel on June 10, 2026. The file contains 521 records taken directly from infected devices, including email addresses, plaintext passwords, and the URLs of the login pages those credentials open. That is more passwords than you would find in a small village, all sitting in one file ready to be used.

Why This Stealer Log Is Dangerous

A small record count does not mean a small risk. Every one of these 521 passwords is stored in plaintext, exactly as it was typed, and matched to the specific site it unlocks. There is no cracking or guessing needed. An attacker can open the file and immediately see which login works where.

What Was Exposed in the Psi.ch Stealer Log

• Email addresses tied to infected devices
• Plaintext passwords for those accounts
• URLs identifying the exact login pages the credentials belong to

Why This Matters for the 521 People Affected

A breach this size can still cause real harm to the people in it. If any of the 521 individuals reused their psi.ch password on other accounts, credential stuffing could give an attacker access to personal email, banking, or shopping logins as well. Account takeover and identity theft are realistic outcomes any time a working plaintext password like this is exposed, regardless of how many records are involved.

How Stealer Logs Like This One Get Created

Stealer log malware infects a device through fake downloads, cracked software, or malicious attachments. Once active, it silently gathers saved browser passwords, autofill data, and session information, then bundles everything into a log file sent back to the attacker. These logs are commonly traded or dumped in Telegram channels, exactly where HEROIC analysts found this one.

Check If You Are Affected

If you have a psi.ch account, do not assume a smaller leak means you are safe. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can find out quickly whether your information was exposed.
