Xavier_Ulp Stealer Log: What Hackers Can Do With 211,031 Logins

On 29-May-2026, a file quietly changed hands inside a Telegram channel, and with it went 211,031 sets of login details. The source, listed as Xavier_Ulp - 360200 Xavier_Group uploaded by a Telegram User, is a stealer log, meaning the data wasn't stolen in one dramatic hack of a single company. It was pulled directly off infected computers, one victim at a time.

Why This Is Dangerous

Stealer logs are arguably more dangerous than a typical company data breach because they capture every account wich happens to be logged in at the moment a device gets infected. That means banking portals, work email, social media, and random shopping sites can all show up in the same file, sitting right next to the plaintext password used to unlock them. There's no encryption to crack here. The credentials are just there, ready to be copied and pasted by anyone who downloads the log.

What Was Exposed

• 211,031 total records
• Email Addresses
• Plaintext Password
• URLs (the exact sites each login belongs to)

Why This Matters

Because the passwords weren't hashed or salted, anyone who gets a hold of this file can imediately try logging into the paired email or website. If a victim reused that password anywhere else, which is extremely common, attackers can widen the damage far beyond the original 211,031 accounts by testing the same credentials across banking, email, and social platforms.

How Stealer Log Breaches Work

A stealer log usually starts with malware disguised as something ordinary: a cracked game, a fake invoice, a free download. Once it lands on a computer, the malware quietly scrapes saved browser passwords, autofill data, and even session cookies, then bundles it all into a single file and sends it back to whoever controls the malware. This kind of infection has occured on an enormous scale over the past few years as info-stealing malware has become cheap and easy to rent. From there the data gets sold, traded, or in this case, uploaded for free on Telegram for anyone to grab.
