A self-described “email prankster” in the UK fooled a number of White House officials into thinking he was other officials, including an episode where he convinced the White House official tasked with cyber security that he was Jared Kushner and received that official’s private email address unsolicited.
Spear phishing victims included:
Scaramucci (prankster masqueraded as Preibus and escalated the conflict between the two and masqueraded as Jon Huntsman Jr offering his help getting rid of people at the White House)
Homeland Security Advisor Tom Bossert (prankster masqueraded as Jared Kushner and invited him to a soiree)
