Objective-See Foundation (OSF) creator and researcher Patrick Wardle first discovered the security hole and disclosed it on Zoom in December last year. Zoom fixed that problem, but introduced another bug in the process. Zoom addressed this as well, but Wardle found yet another flaw. The OSF founder discussed his findings at Def-Con last week. Zoom acknowledged the problem that day and fixed it afterward. This isn’t the first time Zoom has faced security headaches, including on the Mac. In 2019, the company struggled to patch a webcam hacking exploit that relied on a locally created web server. Increased scrutiny of Zoom at the onset of the COVID-19 pandemic in spring 2020 also led to a complete overhaul of the company’s practices. While this has led to changes, it’s clear that Zoom isn’t immune to mistakes. All products recommended by Engadget are selected by our editorial team, independent of our parent company.
