SkyULP Leak Exposes 1.7 Million Logins, More Than Phoenix

HEROIC analysts found a stealer log named "SkyULP Private ULP" shared on a Telegram channel in February 2026. The file contained 1,732,950 records, each combining a stolen email address, its plaintext password, and the website URL where the login was used. To put that in perspective, it is more individual logins than the entire population of a city the size of Phoenix, Arizona.

Why The SkyULP Leak Is Dangerous

ULP stands for "URL, Login, Password," and that format is exactly what makes this kind of leak so usable for criminals. There is no decoding or matching required, each line is a working set of instructions for breaking into someone's account.

Because the credentials came directly from infected devices rather then an old company database, many of these passwords are still active right now.

What Was Exposed In The SkyULP File

• Email addresses
• Plaintext passwords
• URLs linked to each login

Why Nearly 1.7 Million Logins Matter

A leak this size gives criminals enormous reach. Automated bots take the email and password pairs and run credential stuffing attacks against banks, email providers, and online retailers, quietly testing millions of combinations until a match is found.

Every successful match can lead to account takeover, identity theft, or direct financial fraud, especially when the same password protects more than one account.

How A ULP Stealer Log Like This Gets Made

Infostealer malware is typically dropped through pirated software, fake browser updates, or malicious attachments. Once running, it quietly copies saved logins from the victim's browser and packages them into the URL, login, password format seen here.

Individual infections are combined into large "private" files by resellers, who then post them to Telegram groups like this one to build a reputation before selling access to bigger, more valuable batches.
