ABOUT LEAKSYR
"Exposed credentials only help defenders if defenders can find them first." Leaksyr is a threat-intelligence search service over credentials that infostealer malware has already exposed and that third parties have already distributed. It exists so that the people responsible for those accounts and systems learn about the exposure before someone abuses it.
Why We Exist
Leaksyr does not create, buy or trade compromised data. It indexes what has already been exposed so that security teams, incident responders and researchers can detect their own exposure before adversaries exploit it.
Where The Data Comes From
We collect infostealer log archives that third parties have already distributed, parse them and make them searchable. We do not solicit, purchase, crack or resell data, and we do not accept submissions. Every record keeps a reference to the archive it came from, and records are removed on verified request.
Who It Is For
Access is intended for defensive and investigative work: security teams checking their own organisation, incident responders, researchers and authorised investigators. Using the service against the people whose data was exposed is prohibited and leads to termination of the account.
Operational Use Cases
Module: DOMAIN_MON
Brand & Domain Monitoring
Track exposures tied to your domains and brand assets to detect credential leaks early before they are used in credential stuffing attacks.
Metric: Time to detect new exposures
Module: INCIDENT_RES
Incident Response Triage
Confirm scope, validate compromised accounts, and prioritize remediation with searchable evidence from stealers and logs.
Metric: Mean time to scope incidents
Module: TPR_ASSESS
Third-Party Risk Checks
Assess exposure signals from vendors and partners when you have explicit authorization to monitor their attack surface.
Metric: Vendor exposure review cadence
Module: CT_WATCH
Continuous Monitoring
Maintain a steady watch for new exposures via automated alerting to radically reduce dwell time and repeated compromise.
Metric: Dwell time reduction
Platform Core Principles

OSINT-first sourcing specifically structured for defensive cybersecurity.
Transparent terms, operational policies, and built-in system auditability.
Newly collected infostealer logs are added continuously; each record shows its log date and the date it was indexed.
