How Stealer Malware Built the ft7logs Part05 File of 142,767 Logins

HEROIC analysts logged 142,767 stolen login records inside a stealer log file labeled ft7logs unique 20000.part05, uploaded to a Telegram channel in mid August 2026. Every record pairs an email address with a plaintext password and the URL where it was captured, and anyone concerned should scan their email now.

What a Number This Large Actually Means

142,767 is not a headline figure, it is 142,767 individual devices or browsers that had malware quietly copying saved logins in the background. Each one represents a person who had no idea their credentials were being harvested until this file surfaced.

What Was Exposed

• Email Addresses: the anchor for each stolen login, used to identify which account a password unlocks.
• Plaintext Passwords: fully readable and ready to use the moment the file is opened.
• URLs: shows exactly which site or service each credential belongs to, so an attacker can go straight to it.

Why the Scale Raises the Stakes

A file this large gets fed into automated credential stuffing tools that test logins across thousands of sites at once. Even if only a small percentage of these 142,767 passwords are reused elsewhere, that is still thousands of accounts at risk of takeover, fraud, or identity theft.

How a Stealer Log Like This Gets Built

This is not a company database breach. Infostealer malware infected each victim's own device, usually through a cracked download or malicious attachment, then quietly copied browser saved passwords, cookies, and autofill data before sending it all back to whoever controlled the malware. The infected device itself is the real source of the leak.

Are You Part of the 142,767 in ft7logs Part05?

Scan your email first to see if your address appears. If it does, treat the device itself as compromised: run a full malware scan or wipe and reset it before doing anything else. Only after the device is clean should you change passwords, starting with email and banking, since typing a new password into an infected machine just hands it over again. This matters for personal devices and work devices alike.
