Hello Experts
I am a network security engineer.
I am trying to come up with a solution to make Zoom Meeting’s Chat feature safe for users.
The communication with Zoom Meeting is done in plain text with MITM type SSL decryptor on the network to check the content filter and other security checks.
When we applied this solution this time and uploaded a test file to Zoom Meeting chat and downloaded it, the content filter function was not detected properly.
Looking at the communication, we found that the file was split into multiple files.
(1) aaaa.pptx (detected file type pptx)
(2) aaaa.pptx (detected file type zip)
(3) aaaa.pptx (detected file type zip)
… (2) and (3) are observed multiple times.
Is it a Zoom specification that data is exchanged in ZIP format when files are split and downloaded? Is it possible to disable this?
Thanks.
