Researchers discover web conferencing snooping flaw
Earlier this week, researchers at Cequence Security blogged that they’d found a flaw that could allow hackers to snoop on video conferences.
The “Prying-Eye” vulnerability, affecting Cisco WebEx and Zoom video conferencing, exposes open meetings or calls that aren’t protected by passwords. Attackers could use an enumeration attack to gain access, using brute force to guess ID numbers.
Cisco and Zoom were alerted by Cequence back in July – both have since altered default security settings and issued advice to customers.
The NCSC advises using three random words to create a strong password. You should also follow the security advice from video conference software vendors, including setting passwords for meetings.
