Telegram Users Behind the 26_Boss Leak of 775 Stolen Logins

Somewhere on Telegram in September 2023, a user posted a file called 26_Boss containing 775 stolen logins. Not the biggest leak on record, but every single line represents someone whose device was infected without their knowledge.

Why This Is Dangerous

The people who trade these logs typically aren't the ones who wrote the malware. They're middlemen collecting logs, sorting them, and reselling access to whoever is willing to pay. That means your data can travel through several hands before it's ever actually used against you, and you'd have no way of knowing.

What Was Exposed

• Email addresses tied to compromised accounts
• Plaintext passwords captured from the browser
• Endpoint and URL details showing where credentials were used

Why This Matters

A leak this size might not make the news, but that's exactly the problem. Publically reported breaches at least come with notifications and press coverage. Files quietly shared on Telegram like this one often go completely unnoticed by the people affected, leaving them exposed with zero warning.

How Stealer Logs Work

Getting infected usually starts small: a cracked piece of software, a fake game mod, or a link in a message that looks harmless. The malware installs quietly, reads through saved browser credentials, and sends everything to the attacker. From there it's formatted and distributed exactly like the 26_Boss file being discussed here.

Check If You Are Affected

HEROIC has cataloged over 400 billion (400B+) leaked records from stealer logs and breaches across the dark web. It costs nothing to run a scan and check if your email shows up in the 26_Boss leak, so there's no reason to put it off.
