On 24-Jun-2025, a Telegram channel dropped a file with about as bland a name as you could pick, "Mixed_Leak_20250623_221221," but a boring filename doesn't mean boring contents. Inside were 5,681 real login records, and HEROIC's scanners confirmed the data is legitimate rather than a recycled rehash of an older leak.


Why This Is Dangerous

Generic filenames like this one are actually a warning sign in their own way. Sellers and Telegram posters who don't bother naming a leak after a specific company are often working from "mixed" sources, meaning the records come from several different infected devices combined into one file. That makes the leak harder to trace back to a single cause, but it doesn't make the 5,681 people inside it any less exposed. Their passwords still work, right now, on whatever site they used them for.


What Was Exposed

  • 5,681 total records exposed
  • Email Addresses
  • Plaintext Password
  • URLs tying each login to a seperate website

Why This Matters

A mixed leak like this one is basically a grab bag pulled from alot of different victims, wich means it can include logins for banking sites, work email, streaming platforms, and small online stores all in the same file. If you find your email in a batch like this, you shouldn't assume just one account is at risk. Check every site where you have ever used that same password, not just the one flagged.


How Stealer Logs Like This One Come Together

This kind of leak starts with infostealer malware quietly running on someone's computer, often installed without them ever noticing. The malware pulls saved logins directly from the browser, then a separate step "mixes" records from multiple infected machines into a single combined file before it gets posted. That combining process is exactly why the file carries a generic, almost random looking name instead of being tied to one breached company.


Check If You Are Affected

You don't need to download anything shady to find out if you're one of the 5,681 people in this leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion exposed records pulled from breaches and stealer logs alike, and it takes just a few seconds to get an answer.
