Methodology

Bikoosh subscribes to the public Certificate Transparency stream - the log of all newly-issued HTTPS certificates. Each new domain name is tested against deterministic naming rules associated with rental fraud: rental vocabulary combined with destination city names, brand-lookalike patterns (typosquats, hyphen injection), and rental vocabulary on TLDs with high historical abuse rates. Matching is on names only at this stage; a name match is a statistical signal, not a verdict about any specific domain - which is why this report publishes only aggregates and never names domains.

Numbers regenerate weekly from live pipeline data. Weeks run Monday-Sunday, UTC.
