How the valid_phpmyadmin File Leaked 587 Email and Password Logins

HEROIC analysts identified a file called valid_phpmyadmin circulating on Telegram, containing 587 leaked records of emails and plaintext passwords. Each entry also included the URL of the login page it was tested against, exposing real, working phpMyAdmin credentials. The only way to know if your information is part of this list is to scan your email.

Why a Working phpMyAdmin Login Is a Direct Path In

phpMyAdmin controls the database behind a website, so a working login here is not just an inconvenience, it is a door into whatever data that database holds. An attacker who tests one of these 587 pairs and gets in can read, copy, or alter records, plant malicious code, or lock out the legitimate administrator. Because the passwords are stored in plaintext, no cracking is required; the credentials work exactly as they were captured.

What This valid_phpmyadmin File Actually Contains

• Email Addresses: identifies the real person or admin tied to each login attempt.
• Plaintext Password: readable and usable immediately, no cracking needed.
• URLs: points directly to the login page each credential was tested against.

From a Test Login to a Real Compromise

If any of these 587 credentials still works, an attacker can log into a live phpMyAdmin panel and reach the database sitting behind it, which may include customer records, order data, or other sensitive tables. Reused passwords compound the risk. Anyone who reused one of these email and password pairs on a personal account, banking site, or work login has effectively handed over the keys to that account too.

How a Combolist Like This Gets Built

According to HEROIC analysts, files like this are built by testing large batches of known email and password pairs against specific login pages, in this case phpMyAdmin panels, to see which ones still work. The pairs that succeed get compiled into a combolist and traded or sold, while the ones that fail are usually discarded. It is a low effort, automated process, not a targeted attack on any one organization.

What to Do About the valid_phpmyadmin Leak

Start by scanning your email to see if your address is in this list. If it is, change that password everywhere else you have used it, since the plaintext data means it is already usable as is, and set a unique password for every login going forward. This applies whether the account is personal or tied to work, since either kind of credential can appear in a file like this.
