Der Absendername wirkt vertrauenswürdig, die Grafik höchst offiziell, der Ton ist freundlich. Angeblich endet die Testphase für ein Amazon-Prime-Abo in 72 Stunden, danach erfolgt die automatische Umwandlung in ein Zwei-Jahres-Abo. Will man diese verhindern, müsse man aktiv kündigen. Das Problem: Das Abo gibt es gar nicht. Die E-Mail und die dazugehörige Website wurden als Phishing-Falle konzipiert, die Kreditkartendaten abgreifen soll.

subfinder – Passive Subdomain Enumeration Tool

Point subfinder at a domain and it asks dozens of online sources which hostnames they have seen under it, without sending a packet to the target itself. I ran the new 2.17.0 release against this site with no API keys. It returned 17 subdomains in 14 seconds, and when I looked them up in DNS on 13 October, only one resolved.
