Satanic 13.8M ULP on BreachForums Tops 4 Million Unique Victims

On October 8, 2024, a stealer log titled Private Satanic 13.8M ULP was posted to BreachForums by a threat actor operating under the name Satanic. The post claimed 13.8 million total records; deduplication produced 3,972,820 unique email-and-password pairs — roughly equivalent to the entire population of Los Angeles. The dump includes plaintext passwords, meaning every credential in it is immediately actionable. This release is one of more than 20 numbered dumps from the same actor in the Private Satanic series on BreachForums.

Why This Is Dangerous

The Satanic ULP series is one of the most prolific credential dump operations tracked on BreachForums. The 13.8M release alone delivers nearly 4 million unique plaintext credentials with no decryption barrier. At this scale, even a 1% credential-stuffing success rate translates to roughly 40,000 compromised accounts across banks, email providers, and e-commerce platforms.

What Was Exposed

• Email addresses (3,972,820 unique)
• Plaintext passwords — directly exploitable with no processing
• HomePage URLs — revealing victim services and browsing affiliations

Why This Matters

• Credential stuffing: Nearly 4 million plaintext pairs fuel automated attack tools that probe hundreds of sites simultaneously.
• Account takeover: Reused passwords across email, banking, and social media give attackers broad lateral access from a single credential.
• Identity theft: Email access unlocks password resets, exposing personal documents, addresses, and financial data stored in inboxes.
• Organized fraud: The scale and series nature of these dumps suggests a well-resourced actor running sustained fraud operations, not a one-off opportunist.

How Stealer Log Breaches Work

ULP dumps like the Private Satanic series are assembled from infostealer malware infections. The malware — distributed through phishing, fake software downloads, or malicious extensions — harvests credentials stored in browsers, then transmits them to the attacker's infrastructure. Attackers compile thousands of individual infection logs into consolidated URL-Login-Password files. These are then posted to forums like BreachForums for use in credential stuffing, sale to other criminals, or direct exploitation. The Satanic actor's volume and frequency suggests ongoing malware infrastructure rather than a one-time compromise.
