Executive Summary
This 2025 stealer-malware log set contains about 37.7 million records with email addresses, passwords, and IP addresses captured from devices infected by infostealer malware.
ObscureIQ assessment: Extremely high risk. Exposure enables direct account takeover, wallet theft, identity fraud, and compromise of many services at once because the data is captured from live user environments.
Breach Impact
Live infostealer credentials are highly actionable for account takeover; presence typically indicates a device was infected rather than a single site being breached.
