Xavier_Ulp 351000 (Xavier_Group) Quietly Leaked 238,356 Logins

238,356 is how many records HEROIC analysts counted inside the Xavier_Ulp 351000 (Xavier_Group) file, uploaded to Telegram on 27-Aug-2026. Each record pairs an email address with a plaintext password and a URL. That number represents 238,356 separate logins that are readable by anyone who has the file. The only way to know if you're affected is to scan your email.

Why a Quiet Upload Still Poses a Loud Risk

Files like this one rarely arrive with any announcement, they simply appear in a Telegram channel and start circulating. That lack of fanfare does not make the contents any less usable, since every password inside is stored as plain text. The absence of attention is what lets a file like this spread before most people know it exists.

What This Large File Actually Contains

• Email Addresses: Lets an attacker identify the real person behind each record and target them directly with scams.
• Plaintext Password: Stored in plain text, meaning it works immediately with no decryption or guessing required.
• URLs: Points to the exact login page tied to each record, saving an attacker the work of guessing where to try it.

What 238,356 Exposed Logins Can Lead To

At this scale, the risk is not one account, it is however many of the 238,356 records still have active passwords behind them. Each working login can be used for account takeover, and from there to reset other passwords or reach services tied to the same email. The larger the file, the more this risk compounds rather than staying contained.

How a File This Size Gets Compiled

A file of this size is typically built by combining login pairs gathered from many earlier, often older, sources rather than one company's systems being broken into. Whoever compiles it tests which pairs still work across different sites. That process is what turns scattered old data into one large, working list.

Responding to the Xavier_Ulp 351000 Leak

Check the scan above to see if your email is part of this file. If it is, change that password immediately, and change it anywhere else you have reused it, since that overlap is exactly what a file like this is built to exploit. Review both personal and work accounts, since attackers do not distinguish between the two.
