What services does Opera use for its blacklist of dangerous sites

Does anyone know which services Opera queries to determine if a site is known to be dangerous?

By this I mean like how Firefox and Chromium browsers use Google Safe Browsing. What does Opera use?


Opera uses Phishtank and Netcraft

Thanks, but what about for blocking malicious sites?

Yandex I think.
That’s what it says on this Opera help page. Website owners: Handling fraud or malware warnings
