The file labeled Valid cipher1987, uploaded to Telegram on August 22, 2026, pairs 150 email addresses with plaintext passwords and the exact URLs where each one logs in. That complete set, address, password, destination, is what makes a combolist usable straight out of the download. A quick scan of your email will tell you if you're in it.

Why the "Valid" Label Is the Real Warning

Uploaders mark files like this as "valid" after testing every pair to confirm it still logs in successfully. That verification step is what separates a working combolist from a random data dump, it tells an attacker every one of these 150 entries is ready to use right now.


What Was Exposed

  • Email Addresses — the target identifier for each login.
  • Plaintext Passwords — confirmed working, no cracking needed.
  • URLs — shows exactly where each credential is used.

Why Verified Credentials Are Worse Than Unverified Ones

An unverified leak might contain outdated or dead passwords. A file explicitly labeled valid has already had that noise filtered out, so every one of the 150 pairs represents an account an attacker can access immediately.


How a File Like This Gets Assembled

Uploaders collect credentials from various sources, run them through checking tools to confirm which ones still work, then post the surviving, verified list, in this case, under the label cipher1987. It's a compiled, checked combolist, not a report of any single company's systems being broken into.


Curious If Your Login Is One of the 150?

Take a minute to scan your email and find out. If you get a match, change that password immediately, update it anywhere else you've reused it, and turn on two-factor authentication. This applies to work accounts as much as personal ones, verified combolists don't sort by account type.
