The yetnet.ch Dump: 640 Stolen Login Credentials Hit Telegram

HEROIC analysts identified a combolist tied to the yetnet.ch domain, uploaded by a Telegram user on May 25, 2026. The file contains 640 records, each combining an email address with a plaintext password and the URL of the login page it was pulled from.

Why This Is Dangerous

Because these passwords are stored in plaintext, there is no encryption for an attacker to break through. Anyone who downloads this file can immediately begin testing the email, password, and URL combinations against real login pages, with no cracking tools or technical skill required to make use of them.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to the associated login pages

Why This Matters

A file like this is useful for credential stuffing, where automated tools test each stolen email and password pair against many other websites. Because password reuse is common, a leaked yetnet.ch login can end up granting access to unrelated banking, email, or shopping accounts. That kind of access often leads to account takeover, identity theft, and financial fraud.

How This Combolist Was Likely Built

A combolist like this is typically assembled from stolen username or email and password pairs gathered through phishing pages, older data breaches, or malware that quietly harvests saved logins from infected devices. Whoever compiled this file focused on yetnet.ch addresses, packaging all 640 records into a single list before sharing it through a Telegram channel.

Check If You Are Affected

If you have a yetnet.ch email address or reuse passwords across accounts, it is worth checking your exposure now. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, giving you a fast, clear answer.
