Satanic Cloud 5M ULP Part 3 Contains Exactly 1,887,809 Email and Password Pairs
On December 6, 2024, a threat actor using the handle "Satanic" released five stealer log packages to BreachForums in a single session. This page covers Part 3 of that series. The log contains exactly 1,887,809 unique compromised records extracted from a raw file of approximately 5 million lines. Each record pairs an email address with a plaintext password and the specific website URL from which the credential was harvested by infostealer malware.
This is Part 3 of a 5-part series. See all parts:

Why This Is Dangerous
Stealer logs compiled at this scale represent a ready-made toolkit for automated account takeover attacks. The credentials in this log were not obtained by guessing or brute force. They were silently captured from real users' devices at the moment of login, which means every entry is a valid, working credential from a real account. With plaintext passwords and the exact URLs where they apply, an attacker can begin credential stuffing attacks immediately, with no additional preparation needed.
What Was Exposed
The Satanic Cloud 5M ULP Part 3 stealer log exposed the following data types for 1,887,809 unique records:
- Email Address
- Plaintext Password
- HomePage URL (the site each credential was stolen from)
Why This Matters
This type of stealer log exposure feeds directly into the most damaging account-based attacks:
- Credential stuffing: Each email-password-URL triple is immediately testable across other platforms. No decryption or cracking is required.
- Account takeover: Password reuse means a single compromised credential can unlock multiple accounts across banking, email, and retail services.
- Identity theft: Email access enables attackers to intercept password resets, gaining control of financial and government accounts.
- Fraud: Compromised e-commerce or payment accounts enable direct monetary theft.
- Targeted phishing: Knowing the exact service a user's password was stolen from makes impersonation attempts far more convincing.
How Stealer Log Leaks Work
Infostealer malware such as RedLine, Vidar, Raccoon, and Lumma operates by silently harvesting credentials stored in web browsers, password managers, and application autofill caches. After infecting a device through a phishing email, a malicious software download, or a compromised website, the malware extracts and transmits saved logins in ULP format, URL-Login-Password, to attacker-controlled infrastructure. These logs are then aggregated, sorted by uniqueness, and packaged for sale or distribution on criminal forums. The Satanic Cloud series reflects this pipeline: raw logs from many infected devices, deduplicated and distributed in parts to maximize reach.
Check If You Are Affected
Because these credentials come from device-level infections rather than a single breached website, any online account you use could be affected if your device was compromised. Heroic's breach search engine indexes over 400 billion compromised records, including major stealer log series.
