4,967,122 Stolen Logins Traced to the SKYULP PRIVATE ULP 20 Combolist

Every one of the 4,967,122 passwords inside the SKYULP PRIVATE ULP 21-11-2025 20 combolist sits in plain, readable text rather than behind any kind of hashing. HEROIC analysts confirmed this separate SKYULP file, dated November 23, 2025, pairs each password with an email address and a login URL. This file is distinct from other SKYULP files HEROIC has tracked, with its own larger record count. The only way to know if you're affected is to scan your email.

Why a Readable Password Removes the Hard Part for Attackers

A hashed password normally forces an attacker to spend time and computing power trying to crack it before it's useful. A plaintext password skips that step entirely, it can be read and tried on the matching site within seconds of opening the file.

What Was Exposed in This SKYULP File

• Email Addresses: identifies a working inbox that can be targeted with phishing or used as a login.
• Plaintext Password: fully readable, so it can be tried immediately without cracking or guessing.
• URLs: points to the exact site or service each credential pair was tied to.

Why Readable Passwords Put More Accounts in Danger

Since so many people reuse passwords across multiple sites, a single readable password pulled from this file can open far more than the one account it was originally tied to, including email, banking, or social accounts sharing the same login.

How a File This Size Gets Compiled

Combolists at this scale are built by merging email and password pairs pulled from many earlier leaks and malware logs into one large, searchable file. HEROIC analysts track multiple SKYULP files circulating and being refreshed on Telegram, each numbered separately.

What to Do About This SKYULP Leak

Start by scanning your email to check whether your address appears among these records. If you recognize the password, change it on every account where you've reused it and give each one a unique password from now on. This applies to personal and work email alike.
