“45_Boss” Stealer Log Quietly Appears With 1,695 Passwords

The "45_Boss" Stealer Log Quietly Appears on Telegram

HEROIC analysts identified a stealer log named "45_Boss," uploaded by a Telegram user and dated 26-Apr-2024. There was no announcement or fanfare around this file, just 1,695 records of email addresses, plaintext passwords, and URLs quietly circulating among people trading stolen data.

Why This Quiet Leak Is Still Dangerous

A small, unannounced file like this one is easy to overlook, but the risk to the people in it is just as real as any larger, more publicized breach. The passwords are stored in plaintext, so there is no encryption protecting them, and each one is paired with the exact site it belongs to. An attacker does not need to make noise to use this data, they can simply log in.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the exact site each login belongs to

Why This Matters

Anyone in this log faces a direct account takeover risk, whether or not the leak ever makes headlines. Because the password is exposed in plaintext and matched to its site, an attacker can act on it immediately. If that password has been reused elsewhere, the exposure quietly extends to other accounts as well.

How Stealer Logs Work

Stealer logs are the product of malware that infects a device and silently copies whatever the browser has saved, including passwords, autofill data, and site URLs. That stolen information is bundled into a file and delivered to the attacker, who may sit on it, share it quietly, or sell it on Telegram, exactly the kind of low-profile activity that let this file go unnoticed until now.

Check If You Are Affected

Quiet leaks like this one can go undetected for a long time, which is exactly why it pays to check your exposure directly. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you immediately if you were affected.
