Your Data May Already Be Stolen. The Satanic 16M ULP Breach Exposed 2.1 Million Plaintext Passwords.

Your credentials may already be in the hands of attackers. HEROIC analysts discovered the BreachForums Private Satanic 16M ULP by Satanic dataset on September 4, 2024, containing exactly 2,193,813 records drawn from a stealer log upload to BreachForums. The exposed data includes email addresses, plaintext passwords, and homepage URLs, making this one of the more immediately actionable credential dumps in this ongoing series. This release is part of a broader campaign by the same threat actor, who distributed multiple numbered batches across the same platform.

The danger in this dataset is immediate and requires no additional work on an attacker's part. Plaintext passwords mean there is nothing to crack, decode, or reverse. An attacker can take an email and password pair from this file and attempt to log in to banking portals, email providers, and e-commerce accounts within seconds. The inclusion of homepage URLs narrows down which services each victim uses, letting attackers prioritize high-value targets. With over 2.1 million credential pairs available, even a low success rate translates into thousands of compromised accounts.

What Was Exposed

• Email Address
• Plaintext Password
• HomePage URL

Why This Matters

Plaintext passwords are the most dangerous form of leaked credential because they require zero processing before use. Attackers feed these pairs into automated credential stuffing tools that test them across hundreds of services simultaneously. Because many people reuse passwords across accounts, a single stolen credential can unlock email, banking, social media, and workplace accounts. The homepage URLs in this dataset act as a targeting layer, helping attackers route each credential pair to the service most likely to accept it. The result is a rapid, scalable account takeover operation that can begin within hours of a dataset being published.

How Database Breaches Work

A database breach occurs when an unauthorized party gains access to the underlying data store of an application or service, then copies or exports that data. In the case of stealer log compilations like this one, the data is typically harvested by malware installed on victims' devices. The malware silently extracts saved credentials from browsers, password managers, and applications, then transmits them to a command-and-control server. The collected logs are later compiled, deduplicated, and posted to forums like BreachForums either for sale or as free downloads to build reputation. Because the data comes directly from the victim's own device rather than from a single breached company, it can include credentials from dozens of different services in a single record.

Check If You Are Affected

HEROIC's free breach scanner searches across a database of more than 400 billion records to tell you whether your email address or passwords have been exposed in this or any other known breach. If your credentials appear in the BreachForums Private Satanic 16M ULP dataset or a related release, you will want to change those passwords immediately and enable two-factor authentication on every account that uses the same password.
