A waiting room is a feature in video conferencing platforms where participants are temporarily held before being admitted to the main meeting by the host. This security measure helps prevent unauthorized access by allowing the host to screen attendees. However, cybercriminals may exploit the familiarity of waiting rooms in phishing scams, creating fake meeting invites or spoofed waiting room notifications to trick users into revealing sensitive information or downloading malicious software. It's important for users to verify meeting links and be cautious of unexpected prompts related to waiting rooms.
