Inside the BreachForums alien ULP P852 Leak: 9.13M Emails Exposed

HEROIC logged 9,137,790 unique records in the BreachForums alien ULP P852 by alien leak on March 15, 2025. The file formed one slice of a 52.3 million line URL:LOGIN:PASS drop posted on BreachForums, carrying emails, plaintext passwords, and the exact homepage URL each login belonged to.

Why This Stealer Log Is Dangerous

The ULP format removes the guesswork for attackers. Each row already shows which service the credential unlocks, so there is no trial and error, no mass probing of random platforms. Automated tools can go straight to banking portals, email providers, workplace tools, and crypto exchanges with a known working target.

What Was Exposed in the BreachForums alien ULP P852

• 9,137,790 unique email addresses
• Plaintext passwords from compromised browsers
• Homepage URLs pinpointing each account
• Active login pairs across thousands of services

Why This Matters

These credentials feed directly into account takeover, identity theft, and payment fraud. Because passwords appear in plaintext alongside their target site, attackers skip the cracking step and move to immediate exploitation. Shared or reused passwords multiply the damage across every account tied to the same email.

How a Stealer Log Dump Works

Infostealers including RedLine, Vidar, Lumma, and StealC spread through cracked software, malicious ads, and phishing links. Once on a machine they collect browser-saved credentials, cookies, autofill data, and crypto wallet files, then transmit the haul to a collector. Operators like alien bundle the victim logs into numbered ULP parts and release them on BreachForums for the credential stuffing community.

Check If You Are Affected

Change any password stored in your browser, turn on multi-factor authentication for critical accounts, and scan your system for infostealer infections. Search the HEROIC scanner, backed by more than 400 billion breached records, to see whether your email shows up in the BreachForums alien ULP P852 or linked drops.
