A security issue in popular video conferencing platform Zoom was disclosed this week. It could have allowed attackers to crack private meeting passcodes and snoop in on video conferences. The six-digit, numeric passwords protect Zoom meetings, and were added to meetings by default by Zoom in April as an extra security measure to prevent Zoom bombers from freely entering and hijacking meetings. The issue stems from Zoom lacking a fairly standard principle of password security, which is to rate limit password attempts.
