Someone Has Your Password: 304 EU and USA Credentials Leaked

HEROIC's DarkHive threat intelligence platform uncovered a stealer log file labeled "EU and USA Valid Hits" circulating on Telegram in November 2024. Despite its relatively small size of 304 records, this dataset is particularly dangerous because every entry has been pre-validated by the attacker — meaning each email address, plaintext password, and URL combination was confirmed as a working login at the time of collection.

Plaintext Passwords Mean Instant Access

None of the passwords in this leak are encrypted or hashed. They sit in the file as readable text, which means anyone who obtains the dataset can log into affected accounts without any technical effort. When combined with the fact that these are verified "valid hits," the threat is immediate — attackers already know these credentials work.

What Was Exposed

• Email Addresses — belonging to users across European and American services
• Plaintext Passwords — verified as working at the time of extraction
• URLs — confirming which specific sites and services are vulnerable

One Password Opens Many Doors

Even 304 verified credentials can cause significant damage. Attackers use these confirmed logins as starting points for credential stuffing campaigns, testing them against banking portals, email services, cloud platforms, and e-commerce sites. Because most people recycle passwords across accounts, a single validated entry can cascade into unauthorized access across an entire digital life.

Where Stealer Logs Come From

These credentials were extracted by infostealer malware installed on victims' devices without their knowledge. Infostealers spread through fake software installers, malicious browser extensions, and phishing links. They silently capture saved passwords from web browsers, along with cookies and session tokens, then transmit the stolen data to attackers. The compiled logs are sorted, verified for working credentials, and distributed on underground channels.

Check If Your Credentials Were Exposed

HEROIC's breach database contains over 400 billion compromised records and continues to grow as new leaks are discovered. Search your email address using HEROIC's free breach scanner to check whether your credentials appear in the EU and USA Valid Hits dump or any other indexed breach. If you find a match, change your passwords immediately and enable two-factor authentication on every account.
