Israeli Cyber Firm NSO Replaces CEO, Plans Layoffs

TEL AVIV—The Israeli cybersecurity company NSO Group is replacing its chief executive and will lay off 100 employees, the firm said Sunday, in a reorganization that comes after criticism that clients have abused its powerful spyware.

The move follows a U.S. decision last year to blacklist NSO over allegations that its surveillance software, called Pegasus, has been used inappropriately. Those pressures have put the company at risk of defaulting on debt that Moody’s Corp. estimated was around $500 million in November.
