## Public report package

PhishDestroy records the Email Preference Center page captured at preference-centers.firebaseapp.com, which greets visitors and offers an Abuse Team contact link.

The captured page presents itself as an Email Preference Center and opens with a large welcome heading that names preference-centers.md02.com rather than the firebaseapp.com host. It addresses readers who may have arrived from a client email or by mistyping a URL, then places a highlighted box headed "Why am I receiving this SPAM?" that invites recipients who do not recall signing up to contact the linked Abuse Team with details of the message. A closing line offers a further "let us know" link for anyone still having problems.

The stored VirusTotal domain result reports 15 detections out of 92 engines. Bkav reported "malicious"; DNS8 reported "phishing".
