Researchers at Citizen Lab reported some other mayor flaws with zoom; the report shows that some calls were routed through China. The company has offered an apology and an explanation.
To recap, Zoom has faced a barrage of headlines this week over its security policies and privacy practices, as hundreds of millions forced to work from home during the coronavirus pandemic still need to communicate with each other.
The latest findings landed earlier today when Citizen Lab researchers said that some calls made in North America were routed through China — as were the encryption keys used to secure those calls. But as was noted this week Zoom isn’t end-to-end encrypted at all. Despite the company’s earlier claims, meaning that Zoom controls the encryption keys and can. Therefore, access the contents of its customers’ calls. Zoom said in a previous blog post that it has “implemented robust and validated internal controls to prevent unauthorized access to any content that users share during meetings.” The same can’t be said for Chinese authorities. However, which could demand Zoom turn over any encryption keys on its servers in China to facilitate decryption of the contents of encrypted calls.
During normal operations. Zoom clients attempt to connect to a series of primary data centers in or near a user’s region. If those multiple connection attempts fail due to network congestion or other issues. Clients will reach out to two secondary datacenters off of a list of several secondary datacenters as a potential backup bridge to the Zoom platform. In all instances, Zoom clients are provided with a list of datacenters appropriate to their region. This system is critical to Zoom’s trademark reliability, particularly during times of massive internet stress.”Zoom’s CEO Eric Yuan
In other words, North American calls are supposed to stay in North America. Just as European calls are supposed to stay in Europe. This is what Zoom calls its data center, “geofencing.” But when traffic spikes. The network shifts traffic to the nearest data center with the most available capacity. This is understandable, but you have to keep in mind other countries’ policies that change and give them more control than intended. Anyway, the company is still facing pressure from New York’s Attorney general and the two class-action lawsuits that follow.
