In March 2023, a Telegram user released a curated stealer log labeled "valids_cleaned_45000" containing 14,999 verified email-password combinations. The name suggests attackers filtered this dataset to remove duplicates and invalid credentials, creating a highly useable list for account takeover attacks.

Why This is Dangerous

A cleaned and verified stealer log is more valuable than raw dumps because every credential in it has been tested and confirmed to work. Attackers selling or using this dataset know they're targeting live, active accounts. There's no wasted effort trying invalid credentials.

What Was Exposed

  • Verified Email Addresses (14,999 records)
  • Plaintext Passwords (tested and valid)
  • URLs and Endpoint Information

Why This Matters

Cleaned credential lists are the most sought-after commodity in underground markets. A criminal with this list can immediately begin credential-stuffing attacks against other services, knowing they'll have a high success rate. If your email is in this dataset, attackers are actively using it against other platforms.

How Credential Cleaning Works

Attackers run cleaned stealer datasets through automated tools that verify each credential by attempting login. Pairs that work are kept; dead credentials are discarded. The resulting list is sold at premium prices because buyers know they're getting live, working accounts ready for immediate exploitation.

Check If Affected

If you're among the 14,999 verified victims, assume criminals are actively testing your credentials on other sites right now. Change your password on this account and any others using the same credentials. Monitor accounts for unauthorized logins.
