STARLINKULP Breach: What Hackers Can Do With 8.2M Logins

HEROIC analysts uncovered a massive stealer log collection called "STARLINKULP 10 kk" uploaded to a Telegram channel on November 26, 2025. The file contained 8,221,599 records, each combining an email address, a plaintext password, and the URL of the login page where the credential was stolen. This is one of the larger stealer log batches HEROIC has tracked in recent weeks.

Why This Is Dangerous

With over 8 million plaintext email and password pairs in a single file, an attacker does not need to break any encryption or guess anything. They can simply load the list into automated software and start testing logins across hundreds of websites at once. Every matched pair becomes an open door into email, banking, shopping, or social media accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the login pages where credentials were captured

Why This Matters

Attackers who obtain a file this large typically run it through credential stuffing tools that attempt logins across thousands of sites in minutes. If your password is reused anywhere, this single leak can cascade into account takeover on multiple services, opening the door to identity theft and financial fraud. The sheer size of this leak means the odds of any one person being caught up in it are unfortunately high.

How Stealer Logs Work

Stealer malware infects a device, often through a cracked software download or malicious ad, then quietly harvests every saved password, autofill entry, and browser cookie it can find. The results are bundled into a log file and sold or shared in bulk. A batch of this size suggests either a widescale malware campaign or a compilation of many smaller infections combined into one release.

Check If You Are Affected

With millions of records circulating from this single leak alone, it is worth taking thirty seconds to check your own exposure. HEROIC's free breach scanner searches a database of more than 400 billion leaked records to show you instantly if your email or password appears in this breach or any other.
