About Criminal IP
Criminal IP is a search engine for internet-connected devices and a threat intelligence service run by AI Spera, a company based in Seoul. It scans the public IPv4 space continuously, runs honeypots, and combines the results with abuse records, malware and C2 data to give each IP and domain a risk score. Analysts use the search engine to look up exposed ports, services, certificates, vulnerable assets and VPN, proxy or Tor usage, while security teams pull the same data through an API, threat feeds in STIX or MISP formats, or an on-premise database. AI Spera also sells attack surface management and fraud detection products built on this data. Anyone can create a free account with limited lookups, and paid access is a monthly subscription, with enterprise contracts through sales. It runs in the browser and plugs into SIEM, SOAR and firewall tools. It suits analysts who want risk scoring alongside raw scan data; its search interface sits on a separate subdomain from the marketing site.
Best for: Threat hunters and SOC teams who want internet scan data with IP and domain risk scores.
