Malware Harvested 7,601,381 Logins in the STARLINKULP Stealer Leak

Behind the file named STARLINKULP 13 kk is a story of malware quietly doing its job on millions of devices. Uploaded to a Telegram channel in September 2025, the dump contains 7,601,381 records, each one traceable back to a piece of stealer malware that never asked for permission.

Why This Is Dangerous

A leak this large usually begins small, a single infected download here, a fake browser update there, and builds over months as more devices get compromised and their data gets swept into one growing file. By the time it surfaces publicly, it has already touched millions of lives, and the sheer scale makes it nearly imposible to contain once it starts circulating.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs
• 7,601,381 total records exposed

Why This Matters

With over seven and a half million records, this file represents one of the larger stealer logs recently seen making the rounds. Every entry pairs a plaintext password with the site it unlocks, meaning attackers can automate login attempts at scale rather than targeting people one at a time.

How Stealer Logs Work

The malware behind a log like this typically arrives disguised as something harmless: a cracked program, a pirated movie file, or an attachment in a convincing email. Once running, it reads through the browser's saved logins, matches each password to its website, and quietly uploads the haul to a remote server. From there, batches get merged, sorted, and eventually dumped onto channels like the one where STARLINKULP appeared.

Check If You Are Affected

Given the size of this leak, it is worth checking sooner rather than later. HEROIC's free breach scanner compares your email against a database of over 400 billion compromised records, so you can see immediately if you need to change any passwords.
