Among our 2024 findings:
* In 2023, for the second time in three years, more mass compromise events arose from zero-day vulnerabilities than from n-day vulnerabilities. 53% of net-new widespread threat CVEs through the beginning of 2024 were exploited as 0day.
* Nearly a quarter (23%) of mass compromise events arose from well-planned, highly orchestrated zero-day attacks in which a single adversary compromised dozens or hundreds of organizations in one fell swoop, often leveraging custom tooling like proprietary exploits and backdoors.
* 5,600+ tracked ransomware incidents shed more light on the global menace ransomware has become to consumers, businesses, governments, and society.
* 41% of incidents Rapid7 IR saw in 2023 involved remote access to systems without MFA.
