Citizen Lab: Topology of a test call
Topology of a Zoom test call (source: Citizen Lab): During a test of a Zoom meeting with two users, one in the United States and one in Canada, we found that the AES-128 key for conference encryption and decryption was sent to one of the participants over TLS from a Zoom server apparently located in Beijing, A scan shows a total of five servers in China and 68 in the United States that apparently run the same Zoom server software as the Beijing server. We suspect that keys may be distributed through these servers. A company primarily catering to North American clients that sometimes distributes encryption keys through servers in China is potentially concerning, given that Zoom may be legally obligated to disclose these keys to authorities in China.
