Zoom Is Leaking Users’ Email Addresses and Photos to Strangers

Joseph Cox, writing for Motherboard:

The issue lies in Zoom’s “Company Directory” setting, which automatically adds other people to a user’s lists of contacts if they signed up with an email address that shares the same domain. This can make it easier to find a specific colleague to call when the domain belongs to an individual company. But multiple Zoom users say they signed up with personal email addresses, and Zoom pooled them together with thousands of other people as if they all worked for the same company, exposing their personal information to one another. […]

On its website, Zoom says, “By default, your Zoom contacts directory contains internal users in the same organization, who are either on the same account or who’s email address uses the same domain as yours (except for publicly used domains including gmail.com, yahoo.com, hotmail.com, etc) in the Company Directory section.”

Zoom’s system does not exempt all domains that are used for personal email, however. Gehrels said he encountered the issue with the domains xs4all.nl, dds.nl, and quicknet.nl. These are all Dutch internet service providers (ISPs) which offer email services.

Far from the worst thing we’ve learned about Zoom (this week!), but evidence yet again that privacy and security are low on their list of priorities.
