Xavier_Group-3800 Xavier_Log Premium.part3: 43,776 Logins Leaked

HEROIC analysts examined a stealer log named Xavier_Group-3800 Xavier_Log Premium.part3, uploaded to Telegram in November 2025, holding 43,776 records of email addresses, plaintext passwords, and the web addresses each login belongs to. Being part of a larger numbered series, this file represents one slice of a bigger collection effort. Scanning your email is the only way to check if you are in it.

Why This File Is Only Part of a Larger Set

The "part3" in this file's name signals it is one piece of a bigger drop, split into smaller chunks for easier sharing. That does not make the 43,776 records here any less real. Each one still pairs a working email address with a password captured straight from an infected device.

What's Inside Xavier_Group-3800 Xavier_Log Premium.part3

• Email Addresses: identifies a real inbox an attacker can target directly.
• Plaintext Password: fully readable, so it can be used to log in immediately.
• URLs: shows exactly which site or service each stolen login was saved for.

Why a Stealer Log Acts Faster Than an Old Leak

Because this data came from an active device instead of a recycled leak, the passwords are more likely to still be in use right now. An attacker can log into email, shopping, or work accounts the moment they open the file, with no guessing required. That speed is what makes account takeover and follow on fraud more likely with a fresh stealer log.

How a Numbered Stealer Log Series Gets Built

Stealer malware infects a device, often through a fake download or malicious attachment, then quietly collects every saved login it can find. Operators split large hauls into numbered parts like this one before sharing or selling them. No company's servers need to be touched for a file like this to exist.

What Should You Do About This Slice of the Leak?

Start by running a security scan on any device you think might be infected, since removing the malware matters before anything else. From a different, clean device, scan your email to see if your address appears in this file, then change those passwords from that clean device. Do this for personal and work email alike.
