Five of the six digits of the PIN code were visible in a photo posted by the Dutch Defense Minister on Twitter (pin code to enter the confidential video conference of EU defense ministers).
Mr Verlaan managed to access the meeting after Dutch Defence Minister Ank Bijleveld tweeted a photo that contained the login address and part of the PIN code.
“After a number of attempts, RTL Nieuws succeeded in guessing the PIN code of the secret consultation, because five of the six digits of the pin code were visible in the photo,” the news outlet said.
