It isn't the first case of electronic spying, but it's a doozy. Security researchers found evidence of attempted or successful installation of Pegasus, software made by an Israeli cybersecurity company, on 37 phones of activists, journalists, and businesspeople who appear to have been the targets of potentially intense secret surveillance. The phones were on a list of more than 50,000 phone numbers for politicians, judges, lawyers, teachers and others.
