leaksear.ch indexes known leak sources and accepts reviewed researcher submissions. Source metadata and record counts help researchers judge coverage before searching.
Research Workflow
Filter leak sources, search exposed fields, and move from exposure checks to response.
Combine category, authenticity, visibility, date, record-count, and exposed-field filters.
Each source has categories and an authenticity status. Only reviewed provenance is marked verified.
Search emails, usernames, phone numbers, IP addresses, names, password hashes, and other exposed fields.
Search, triage, report, and follow up in one place.
We review account requests for legitimate security research and incident response.
Connect internal tools through the REST API or MCP server.
