HEROIC Analysts Link the 400k Pass Extracted File to 824 Logins

HEROIC analysts link a Telegram file named 400k Pass extracted, dated March 2021, to 824 confirmed records of email addresses, plaintext passwords, and login URLs. The name promises hundreds of thousands, but what HEROIC actually traced inside the shared file is a much smaller, fully readable batch of 824 working logins. Scanning your email is the quickest way to see if you are one of them.

Tracing a File Back to What It Really Contains

Names attached to combolists are often written to attract attention rather than describe contents accurately. What matters is not the number in the file name, it is the 824 actual entries HEROIC confirmed, each one a real email and password pair someone can test right now.

What HEROIC Found Inside This File

• Email Addresses: point an attacker toward a specific inbox for phishing or recovery attempts.
• Plaintext Passwords: stored in fully readable form, usable the moment they are opened.
• URLs: confirm exactly which login page each password pair belongs to.

Why the Smaller Real Number Still Matters

Eight hundred twenty four working credentials is still 824 chances at account takeover. Anyone whose password shows up here risks losing access to that specific account, plus any other account protected by the same password if it was reused.

How HEROIC Confirms What a File Actually Holds

A combolist gathers email and password pairs from earlier sources and packages them under whatever name the uploader chooses. The name itself does not indicate that a single company was hacked, and it often overstates or understates the real count, which is why HEROIC checks the contents directly.

Are You One of the 824 in the 400k Pass Extracted File?

Settle it now by choosing to scan your email. If your address appears, change that password immediately, and update it anywhere else you used the same one, since a confirmed match here means the credential is real and current. This matters for work email addresses just as much as personal ones.
