Overnight on BreachForums, the StarLinkClouds 11M ULP Went Live

HEROIC found 3,914,680 unique records in the BreachForums StarLinkClouds 11M ULP by VitVit leak on March 19, 2025, exposing email addresses, plaintext passwords, and homepage URLs pulled from stealer malware logs. The dump surfaced on BreachForums under a listing promising 11 million lines of credential material and instantly became one of the most dangerous combo lists of the quarter.

Why This Stealer Log Is Dangerous

Every line in this file reads URL, login, and password in the clear. There is no hashing, no salt, no guesswork. Criminals can paste the list directly into automated bots and test millions of logins against banking, streaming, email, and workplace portals in minutes. Because the URLs identify exactly where each credential was captured, attackers bypass the normal trial-and-error of credential stuffing and go straight for verified hits.

What Was Exposed in the StarLinkClouds 11M ULP

• 3,914,680 unique email addresses
• Matching plaintext passwords for each account
• Homepage URLs showing the exact login site
• Full URL:LOGIN:PASS triples formatted for automated stuffing

Why This Matters

Plaintext credentials linked to specific sites create immediate account takeover risk. A single reused password can chain into email hijack, wire fraud, cloud storage theft, and identity fraud. Stealer logs also reveal corporate SSO portals, VPN gateways, and admin consoles, giving threat actors a direct path into business networks and opening the door to ransomware operators who buy this data for initial access.

How a Stealer Log Dump Works

Stealer malware such as RedLine, Vidar, Raccoon, and Lumma infects a victim through a cracked installer, a malicious ad, or a phishing attachment. Once running, it silently scrapes saved browser credentials, cookies, autofill data, and crypto wallets, then uploads everything to a collector. Operators bundle thousands of victims into a single ULP file and sell or drop it on forums like BreachForums, where aggregators like VitVit combine multiple logs into mega-lists.

Check If You Are Affected

If any of your passwords are saved in a browser, assume stealer logs are a real risk. Rotate credentials for high-value accounts, enable multi-factor authentication, and run a device scan for infostealer activity. You can search the HEROIC scanner, which indexes more than 400 billion breached records, to see whether your email appears in the StarLinkClouds 11M ULP or other stealer log dumps.
