Breach Intelligence Summary
Entity: Data Troll Stealer Logs · Actor: Unknown (infostealer operators) · Sources: 2 references
Attack: Malware / Infostealer
Profile: Malware / Infostealer · Credential theft and device data exfiltration · Aggregated infostealer log dataset · Global
Timeline: Breach (2025-06-01) · Indexed (Aug 13, 2025) · Year (2025.0)
Exposure: Undisclosed records · 2 fields: Email Address, Password
Status: Compilation
Executive Summary
The "Data Troll" stealer-log corpus comprised about 2.7 billion rows containing 109.5 million unique email addresses, along with the passwords used and the websites they were entered into. It was aggregated from many prior infostealer infections rather than a single new breach and drove sensational "16 billion password" coverage in mid-2025.
ObscureIQ assessment: Presence often indicates a device was infected at some point; mitigation is resetting reused passwords, enabling MFA, and ensuring no active infostealer remains.
Breach Impact
Live infostealer credentials tied to specific sites are highly actionable for account takeover; much of the corpus is recycled, so presence may reflect older infections.
About Data Troll Stealer Logs
This record is an aggregated corpus of information-stealer logs distributed under the name "Data Troll," not a breach of a single organization.
Why They Hold Your Data
Aggregated stealer log corpora collect credentials, cookies, browser histories, device identifiers, wallet artifacts, and system metadata pulled from many infected devices into a centralized archive. The workflow is large-scale ingestion, consolidation, and formatting of exfiltrated endpoint data for search and reuse.
Recent Developments
It underlies the June 2025 "16 billion passwords" headlines, which in reality described a compilation of largely repurposed older stealer logs with a smaller portion of new material.
