Universe_Logs Breach Exposes 9,272 Plaintext US Passwords

HEROIC analysts identified a stealer log labeled Universe_Logs 350 Cloud Logs Private Logs Sample circulating on a Telegram channel on November 22, 2025. The file contained 9,272 records taken from infected US devices, each pairing an email address with a plaintext password and the URL that credential unlocks.

Why This Is Dangerous

Every login in this file is stored in plain text, meaning there is no encryption standing between an attacker and a working account. Combined with the exact URL each credential is tied to, this data can be turned into automated login attempts almost immediately, no cracking or guesswork required.

What Was Exposed

• 9,272 individual records
• Email addresses
• Plaintext passwords
• Associated login URLs
• Endpoint data concentrated in the United States

Why This Matters

The consequences of a plaintext credential leak rarely stop at the original account. Attackers feed exposed email and password pairs into credential stuffing tools that test the same login across banking, retail, and email platforms in bulk. If you reused this password elsewhere, that account becomes vulnerable the moment the list is run, and the exposed email address alone opens the door to targeted phishing and account recovery fraud.

How Stealer Malware Creates Logs Like This

This data was not stolen from a company database, it was harvested one device at a time by infostealer malware. Once installed, often through a cracked download or a disguised installer, the malware quietly copies saved browser passwords, cookies, and autofill entries, then sends the haul back to its operator. Those operators package harvests like this 9,272-record sample and post them on Telegram to build a reputation or attract buyers for larger private collections.

Check If You Are Affected
