Dark Web Intel: chez.com Stealer Log Exposes 19,666 Logins

A Stealer Log Tied to chez.com Surfaced on Telegram

HEROIC analysts identified a stealer log file dated 10-Jun-2026 that was uploaded to a Telegram channel by an individual user. The file contained 19,666 records connected to chez.com, including email addresses, plaintext passwords, and the URLs of the login pages where those credentials were entered. Because the passwords were stored in plaintext, anyone who obtains the file can use the logins right away without needing to crack anything.

Why This Is Dangerous

Stealer logs are collected by infostealer malware running quietly on an infected device, which copies saved browser logins and sends them back to whoever controls the malware. Because each record pairs an email address with a plaintext password and the exact site it was used on, an attacker can log in directly. If the same password is reused on other accounts, they can try it there too.

What Was Exposed

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

Why This Matters

With almost 20,000 records in this file, the risk is not theoretical. Plaintext credential pairs like these are exactly what automated tools use for credential stuffing, testing stolen email and password combinations against banking sites, email providers, and online stores. Anyone who reused this password elsewhere is at risk of account takeover, which can lead to identity theft and financial fraud once an attacker gains a foothold.

Dark Web Intel: How Stealer Logs Circulate

Stealer logs are the product of infostealer malware, malicious software that quietly harvests credentials, autofill data, and browsing history saved in a victim's web browser. Once collected, the malware operator packages this data into a log file and circulates it through Telegram channels and dark web marketplaces, which is exactly how HEROIC analysts found this chez.com data. Because the credentials come straight from the victim's device, they tend to still be active and valid, making stealer logs a favorite tool among criminals.

Check If You Are Affected

If you have ever logged into chez.com or a similar site, it is worth checking whether your details appear in this or another leak. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, so you can quickly find out whether your email address or passwords have been exposed and act before an attacker does.
