You can password-protect your Zoom meetings manually by going to the Meetings tab and then clicking the Edit button under your personal meeting ID. “We are looking into unique edge cases to determine whether, under certain circumstances, users unaffiliated with an account owner or administrator may not have had passwords switched on by default at the time that change was made,” it added as quoted by the publication. The company said in a statement to The Verge that passwords for new meetings have been enabled by default since last year. This is something that Zoom also recommends and enables by default, as highlighted on one of its support pages. Having said that, the zWarDial tool seems to have no impact on meetings that are protected by a password. The term for causing disruption has even become famous as “Zoombombing”. Some instances of disrupting virtual meetings by entering without an invite were noticed in the past.
This could also allow individuals to join meetings between some professionals or even an online class for school students. Guessing of random IDs isn't difficult for hackers as each Zoom meeting ID consists of nine to 11 digits, as noted by Kerbs. Also, it is touted to have a 14 percent chance of finding an open meeting each time it tries to attempt with a random meeting ID. The program uses software-level automation to arrange information about 2,400 Zoom meetings that can include links to join each of those meetings, the date and time of the meeting, and the name of the organiser among other details. The tool is said to have the ability to evade the restrictions that the video conferencing app has in place to block automated meeting scans and helps find meetings that aren't protected by a password. Security professional Trent Lo and his fellow members of Kansas City-based security meetup group SecKC have built the zWarDial tool that scans for meeting IDs by routing the searches through various proxies on Tor, as reported by cybersecurity expert Brian Kerbs. In a separate news, Zoom has disabled a feature on its platform that would help meeting hosts see the LinkedIn profiles of individuals, without requiring any explicit permissions. The tool called zWarDial is also said to have a success rate of around 14 percent for each instance. However, security researchers are able to highlight its loopholes through an automated tool that can bypass the measures and find 100 Zoom meeting IDs in an hour.
Zoom has claimed to have shifted its focus towards user privacy and security, and the company recently even started restricting uninvited attendees from virtual meetings.
