The global commercial spyware market will expand over the next five years as demand for advanced surveillance tools by governments surges, says a new report from the U.K’s National Cyber Security Centre.

The NCSC report, which defines the proliferation of surveillance tools such as NSO Group’s Pegasus as a threat, assesses that at least 80 countries have purchased advanced spyware apps.

Backlash against commercial spyware in some European political circles and in the United States has increased even as the industry itself has grown larger.
