How certificate findings are selected

Reported: PhishTank or PhishDestroy reports the hostname as phishing. Listed: CERT Polska, MetaMask, USOM, MODA, NPA 165, JPCERT/CC, the AMF, the FSMA or BaFin lists it, in the source's own category. Phishing host: the name resolves to an address on DomainSpoof's phishing-host list, the addresses that hosted confirmed phishing in the last 48 hours. Spamhaus DROP: it resolves to an address on the Spamhaus DROP list. Same certificate: it shares a certificate with a finding and has listing evidence of its own, a report or listing by a source or its own Spamhaus DROP address.

DomainSpoof reads public certificate logs and the feeds on Sources every hour. A hostname matches Arbitrum when a label carries the brand's name, by the rules on How it works. A lookalike spelling of an official domain matches too. A hostname with two kinds of finding is one row. Details shows the recorded checks, the source's claim and the check times available.
