7 Plaintext Passwords Dumped in Good_Adminer Leak

In March 2026, HEROIC uncovered a stealer log file named Good_Adminer circulating on Telegram. The dump contains 7 records, each pairing an email address with a plaintext password and the URL of an Adminer database management interface. Because Adminer provides direct access to database backends, these credentials carry elevated risk—a compromised Adminer login can expose entire databases, not just individual user accounts.

Plaintext Passwords Eliminate All Barriers

The 7 passwords in this file are stored in plaintext. They have not been hashed, encrypted, or obscured in any manner. Any attacker who obtains this file can read the passwords directly and attempt to log in without any additional effort. For credentials to database management tools like Adminer, this level of exposure is especially dangerous.

What Was Exposed

• Email Addresses — account identifiers tied to database administration panels
• Plaintext Passwords — 7 fully readable credentials requiring no decryption
• URLs — direct links to Adminer interfaces managing backend databases

Database Credentials Amplify Credential Stuffing Risks

Adminer credentials are not ordinary user logins. They provide access to database management tools that can read, modify, or delete entire data stores. Beyond the databases themselves, these 7 email-password pairs will be tested through credential stuffing against email providers, hosting panels, cloud platforms, and any other service where the victim may have reused the same password.

Infostealer Malware: The Source of the Dump

Good_Adminer is a stealer log produced by infostealer malware running on compromised devices. The malware extracts credentials stored in web browsers—including bookmarked Adminer login pages—and packages them into organized log files. These files are then distributed on Telegram, giving a wide audience of cybercriminals access to sensitive database management credentials that were never meant to be exposed.

Check If Your Credentials Were Exposed

If you manage databases through Adminer or similar tools, verify your exposure immediately. HEROIC's breach scanner covers more than 400 billion compromised records. Search your email address or domain to check whether your credentials were leaked in the Good_Adminer dump or in any other known data breach. Change any exposed passwords, rotate database credentials, and implement multi-factor authentication on all administrative interfaces.
