WebEx from insecure location was the operational mistake.

BERLIN - The audio of a German high-level military discussion on Ukraine was intercepted by Russia because a participant had joined the Webex call from an unsecured line from a hotel in Singapore

An unsecured . . . You mean he dialed in? Wtf are they doing on webex in the first - y’know what -nevermind. Sure. What the hell high-level discussions on whatsapp, whatever. . . . Am I the only one who gives a shit about the rules?!
