Hours after security researchers at Citizen Lab informed the committee that some Zoom calls were routed through China, the video conferencing programme has offered an defense and a partial explanation.
To recap, Zoom currently facing a barrage of headlines this week over its security policies and privacy rehearsals, as hundreds of millions forced to work from home during the coronavirus pandemic still need to communicate with each other.
The recent detects acre earlier in the day when Citizen Lab researchers was indicated that some calls induced in The americas 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 says, meaning that Zoom controls the encryption keys and can therefore access the contents of its purchasers’ orders. Zoom said in an earlier blog announce that it has ” implemented robust and ratified internal ascendancies to prevent unauthorized access to any content that users share during engagements .” The same can’t be said for Chinese arbiters, however, which could demand Zoom turn over any encryption keys on its servers in China to facilitate decryption of the content of encrypted calls.
Zoom now says that during its efforts to ramp up its server capacity to accommodate the massive influx of users over the past few weeks, it “mistakenly” granted two of its Chinese data centers to accept calls as a backup in the event of structure congestion.

During normal operations, Zoom clients attempt to connect to a series of primary datacenters in or near a user’s region, and if those several communication aims flunk due to network congestion or other issues, clients will reach out to two secondary datacenters off of a roll of several secondary datacenters as a possible backup bridge to the Zoom platform. In all instances, Zoom clients is supplied with a roster of datacenters appropriate to their region. This organization is critical to Zoom’s trademark reliability, particularly during times of big internet stress .”
In other words, North American calls are supposed to stay in The americas, 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 accessible capacity.
China, however, is supposed to be an exception, mainly due to privacy concerns among Western corporations. But China’s own laws and regulations mandate that companies controlling on the mainland must keep citizens’ data within its borders.
Zoom said in February that” rapidly added ability” to its Chinese regions to handle demand was also put on an international whitelist of backup data centers, which meant non-Chinese users were in some cases connected to Chinese servers when data centers in other regions were unavailable.
Zoom said this happened in ” extremely limited circumstances .” When contacted, a Zoom spokesperson did not quantify the number of users affected.
Zoom said that it has now made that mistaken whitelisting. The fellowship just said useds on the company’s dedicated government propose were not affected by the accidental rerouting.
But some questions remain. The blog announce only briefly addresses its encryption motif. Citizen Lab criticized the company for” flattening its own” encryption — otherwise known as structure its own encryption strategy. Experts have long rejected acts by companies to build their own encryption, because it doesn’t undergo the same scrutiny and peer review as the decades-old encryption standards we all use today.
Zoom said in its protection that it can ” do better” on its encryption intrigue, which it says embraces a” massive wander of use events .” Zoom also said it was consulting with outside experts, but when asked, a spokesperson declined to list any.
Bill Marczak, one of the Citizen Lab investigates that authored today’s report, told TechCrunch he was ” conservatively confident” about Zoom’s response.
” The bigger publish here is that Zoom has apparently written their own scheme for encrypting and procuring asks ,” he said, and that” there are Zoom servers in Beijing that have access to the meeting encryption keys .”
” If you’re a well-resourced entity, find a print of the internet commerce containing some particularly high-value encrypted Zoom call is perhaps not that hard ,” said Marcak.
” The immense transformation to scaffolds like Zoom during the COVID-1 9 pandemic spawns programmes like Zoom enticing targets for many different types of intelligence agencies , not only China ,” he said.” Fortunately, the company has( still further) hit all the right memoes in responding to this new wave of inquiry from protection researchers, and have committed themselves to make improvements in their app .”
Zoom’s blog announce get stations for opennes. But the company is still facing pressure from New York’s attorney general and from two class-action prosecutions. Time today, several lawmakers demanded to know what it’s doing to protect users’ privacy.
Will Zoom’s mea culpas be enough?
