Google's Threat Analysis Group (TAG) and Google subsidiary Mandiant said they've observed a significant increase in the number of zero-day vulnerabilities exploited in attacks in 2023, many of them linked to spyware vendors and their clients.

Last year's count reached 97 zero-days exploited in attacks, representing a surge of over 50 percent compared to the previous year's 62 vulnerabilities. Despite this rise, the figure remains below the peak of 106 zero-day bugs exploited in 2021.
