Zoom buys encrypted messaging platform Keybase to patch privacy holes

Zoom acquired Keybase, a New York-based encrypted messaging platform, for an undisclosed amount.

Why it matters: This is Zoom's first-ever acquisition in its nine-year history, and comes as the videoconferencing giant scrambles to patch security holes. The deal is intended to let Zoom offer end-to-end encryption for calls with large numbers of participants, which has proven to be challenging for rivals, although it only plans to make the feature available to paying customers.
