The SKYULP Leak: 1.7 Million Passwords Exposed. Yours Might Be One.

HEROIC analysts identified a new combolist, tracked under the name SKYULP PRIVATE ULP, after it was uploaded to a Telegram channel by an anonymous user on May 13, 2026. The file contains 1,721,799 individual records, each pairing an email address with a plaintext password and the URL of the site that login belongs to, effectively handing anyone who downloads it a ready-made list of working credentials.

Why the SKYULP Combolist Is Dangerous

Because the passwords in this file were stored and leaked in plaintext, there is no encryption for an attacker to break. Anyone with the file can open it and immediately see usable email and password pairs. Combined with the URL field, which points to the exact website each credential unlocks, the leak effectively pre-sorts stolen logins by target site, making it simple to automate login attempts at scale.

What Was Exposed in the SKYULP Leak

• Email addresses
• Plaintext passwords
• URLs identifying the associated website for each login

Why This Matters for the 1.7 Million People Affected

Most people reuse the same password, or a close variation of it, across several accounts. When a plaintext password is tied to both an email address and the site it belongs to, attackers can move directly to logging in rather than guessing. That opens the door to account takeover on the original site and, for anyone who reused the password elsewhere, on banking, email, and social media accounts too. From there, the path to financial fraud and identity theft is short.

How a Combolist Like SKYULP Gets Built

A combolist is a compiled file of "combo" entries, email or username paired with a password, gathered by criminals from many smaller sources such as older breaches, phishing kits, and stealer malware logs. These lists are cleaned, deduplicated, and often organized by target website before being sold or shared for free on Telegram and dark web forums, exactly how the SKYULP file surfaced. Attackers then feed the list into automated tools that test each pair against dozens of popular sites in minutes, a technique known as credential stuffing.

Check If You Are Affected by This Breach

If you have used any of the email addresses now circulating in the SKYULP combolist, your password may already be in criminal hands. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including this one, so you can find out in seconds whether your information was exposed and take action before it is used against you.
