The videoconferencing application Zoom, the use of which has exploded with the spread of telework and social distancing from the coronavirus, is in the crosshairs of the Attorney General of New York, worried about the growing number of users whose meetings have been hacked.

He did not disclose the exact content of the letter, simply emphasizing that the prosecutor hoped to work with the company to resolve the problems found.
