Data Sources Covered
This free tool checks against legal sanctions lists and ransomware threat intelligence. Sanctions and ransomware results are clearly separated, a Ransomwhere match indicates ransomware-associated risk, not a legal sanction.
See full screening platformOFAC (US Treasury)
Digital currency address records from the OFAC SDN list. A match means the address is on a US sanctions list.
UN & EU Sanctions
Crypto addresses tied to the UN Security Council Consolidated List and the EU Consolidated Financial Sanctions List.
Ransomwhere (Threat Intel)
Crowdsourced ransomware payment addresses. A match flags ransomware-associated risk and is unverified intelligence, not a legal sanction.
