An attacker created a Google Calendar event with a voicemail lure that caused Google to send an authenticated calendar notification containing a google.com redirector to a freshly-registered malicious domain (voiceml.space); automated scanners returned conflicting verdicts (wrapper scored clean, bare domain partial) and a VIP recipient reported the event, preventing compromise.
