How Malware Led to 88,137 Stolen Logins in Universe_ULP

HEROIC identified a substantial stealer log archive labeled Universe_ULP 250000 ULP Lin that was shared on Telegram in November 2025. The collection contains 88,137 credential records harvested from compromised devices by infostealer malware. The naming convention suggests this is part of a larger 250,000-record collection, with this segment representing a significant portion of the stolen credentials.

88,137 Passwords Without Any Encryption

Every credential in the Universe_ULP dump was captured and stored in plaintext. The passwords are recorded in their exact original form, without any hashing or encryption that might slow down exploitation. An attacker with access to this file can read and use every single password immediately, making the 88,137 accounts in this collection vulnerable to instant takeover.

What Was Exposed

• Email Addresses — tens of thousands of unique email accounts serving as login identifiers and potential phishing targets
• Plaintext Passwords — unencrypted credentials harvested directly from infected devices, ready for immediate exploitation
• URLs — the specific websites, web applications, and online services where each credential was originally entered and captured

The Credential Stuffing Pipeline

With 88,137 credential pairs, attackers feed this data into automated stuffing tools that work around the clock. Each email-password pair is tested against major online services including banking platforms, email providers, social networks, and corporate login portals. The widespread habit of password reuse ensures that a meaningful percentage of these credentials will unlock additional accounts beyond the ones originally compromised, creating a multiplier effect that extends the damage far beyond the initial 88,137 records.

From Malware Infection to Telegram Distribution

The journey of these credentials began when infostealer malware infected each victim's device, typically through a deceptive download, a malicious email link, or a compromised software installer. The malware embedded itself silently, then began systematically extracting saved passwords from all installed browsers, harvesting cookie data for active sessions, and capturing form autofill information. These individual theft events were aggregated into a structured ULP-format log and uploaded to Telegram, where the Universe_ULP collection became publicly accessible to criminals worldwide.

Check If Your Credentials Were Exposed

HEROIC's breach scanner draws from a database of over 400 billion compromised records to check if your email or password appeared in the Universe_ULP dump or any other known breach. With 88,137 records in this collection alone, checking your exposure is a prudent step. Search now and act immediately if your credentials are found.
