Not 278,000 like the file's own name suggested. When HEROIC's researchers actually opened up the "278000 100Private M_P" file uploaded to Telegram back in August 2023, the real, verified count came out to 138,372 records, still a significant number, just not the one the uploader advertised.


Why This Is Dangerous

Inflated file names are common in this space, sellers pad the numbers to make a listing look bigger and more impressive. But the actual figure here, 138,372 email and password pairs, is more than enough to cause serious harm, and honestly the precision of a verified count matters more than a rounded, definately exaggerated headline number.


What Was Exposed

  • Email Addresses
  • Plaintext Passwords
  • URLs tied to the accounts
  • 138,372 verified records

Why This Matters

Whether a leak claims 278,000 or actually contains 138,372, the people inside it face the exact same risks. Passwords stored in plaintext give attackers an imediately usable credential, no cracking or decrypting required. Anyone reusing a password tied to this leak on a seperate account is extending the blast radius well past the original file.


How Stealer Logs Work

Files like this one usually start as a much larger, messier stealer log collection, and sellers often round up or exaggerate the true count when they post it for sale. Once analysts strip out duplicates and dead entries, the real number, in this case 138,372, tends to be noticeably smaller than the marketing headline but still entirely usable by whoever buys it.


Check If You Are Affected

An exact number is only useful if you know whether you are one of the people in it. HEROIC's free breach scanner checks your email against more than 400 billion breached records so you get a real, verified answer instead of a guess.
