Zoom won’t allow you to join meetings if you do not update it to Latest version before 30th May


Update your Zoom app to the latest version before 30th May else you won’t be able to join the zoom meetings

Zoom is a video conferencing app that allows users to communicate with each other by creating rooms that can contain up to 100 users at a time. Zoom has faced multiple downturns in the past because of the quality of security. The app was also been hit by the hackers where 500,000 Zoom accounts on sale on the dark web for less than $0.002 each. Now after making multiple security changes in the past few weeks the officials want you to update the Zoom app to the latest version before 30th May.

Beginning May 30, 2020, all Zoom clients and Zoom Rooms must be on version 5.0 or greater to join any meetings, as GCM encryption will be fully enabled for all meetings. Upgrade to the latest Zoom Rooms software in your Zoom Admin Portal for both your room computer and your Zoom Rooms Controller as soon as you can. On May 30, Zoom will cut over all accounts to GCM encryption.

What is GCM Encryption? How it protects users’ security?

In cryptography, Galois/Counter Mode (GCM) is a mode of operation for symmetric key cryptographic block ciphers widely adopted for its performance. GCM throughput rates for state-of-the-art, high-speed communication channels can be achieved with inexpensive hardware resources. The operation is an authenticated encryption algorithm designed to provide both data authenticity (integrity) and confidentiality. GCM is defined for block ciphers with a block size of 128 bits.

This release delivers one of our most advanced security enhancements to date with support for AES 256-bit GCM encryption, which provides added protection for meeting data and greater resistance to tampering. So, what does this new encryption algorithm mean for you, and what other security functionality should users be aware of in this new release? Here are 5 things you should know about Zoom 5.0:

1. AES 256-bit GCM encryption

Zoom 5.0 supports our current encryption and GCM encryption. System-wide account enablement to GCM encryption will occur on May 30, 2020, and only Zoom clients on version 5.0 or later, including Zoom Rooms, will be able to join Zoom Meetings starting May 30.

2. Report a User feature

Meeting hosts and co-hosts can report a user in their meeting who is misusing the Zoom platform. Found in the Security icon, the option sends a report to Zoom’s Trust & Safety team for review. The report can include a specific offense, description, and optional screenshot. The Report a User function is on by default but can be turned off at the account, group, and user level in the Zoom web portal.

3. New encryption icon

A new encryption shield appears in the upper left of your Zoom Meeting window and indicates a secure, encrypted meeting. After May 30, the shield will be green for all users, denoting enhanced GCM encryption. Clicking the icon also takes you to the Statistics page for additional encryption details.

4. Enhanced data center information

Meeting hosts can now select data center regions at the scheduling level for meetings and webinars. The Zoom client also shows which data center you’re connected to in the Info icon in the upper left of your Zoom window. You can get additional details in-meeting by selecting Video Settings – Statistics in the meeting controls. Additionally, if organizations outside of China did not opt into the China data center before the April 25 deadline, those accounts will not be able to connect to mainland China for data transit.

5. Enhancements to ending/leaving meetings

We’ve refined the act of ending or leaving a Zoom Meeting to make it easier and also more secure. With a new UI update, hosts can clearly decide between ending or leaving a meeting. If the host leaves, they can now easily select a new host and have the confidence that the right person is left with host privileges.

Zoom has also added some more security features that are listed below:

  • Profile picture control: Account admins and hosts can disable the ability for participants to show their profile picture and also prevent them from changing it in a meeting.
  • Minimum password length: The minimum default password length will be six characters for meetings, webinars, and cloud recordings.
  • Cloud recording security: Admins and meeting hosts can set expirations on their cloud recordings and can disable the sharing of their recordings.

Customers with third-party SIP and H.323 conference rooms that connect using Zoom’s Conference Room Connector (CRC) will not require any action as this change does not impact third-party device encryption. Zoom has upgraded the cloud-hosted room connector to ensure compatibility with all GCM meetings.
