Hackers Published 1M Records From the LeakBase 8.7M ULP Breach

HEROIC found the LeakBase 8.7M ULP by firegoon Stealer log breach dated April 2024, exposing 1,026,287 records including email addresses, plaintext passwords, and homepage URLs from LeakBase 8.7M ULP by firegoon, an infostealer credential log compiled from infected devices and distributed across criminal forums.

Why the LeakBase 8.7M ULP Breach Is Dangerous

Over one million plaintext password-email pairs, each paired with the victim's homepage URL, give attackers a ready-made credential stuffing toolkit. Criminals immediately run these credentials through automated bots targeting banking, email, and e-commerce platforms, using the homepage URLs to prioritize which accounts to hit first.

Why This LeakBase 8.7M ULP Data Puts You at Risk

Plaintext passwords from stealer logs are immediately weaponized in credential stuffing attacks. If you reuse passwords, a single exposed credential can unlock your email, bank, and social media accounts. At over one million records, the probability that your credentials appeared in this log is significant if you have clicked on phishing links or downloaded untrusted software in recent years.

How Stealer Logs Work

Stealer logs are created by infostealer malware that infects victim devices through phishing emails, malicious downloads, or software vulnerabilities. Once installed, the malware silently harvests saved browser passwords, cookies, and form data before transmitting the stolen credentials to criminal operators. The logs are then compiled and sold or shared on underground forums for use in account takeover attacks.
