The GreyNoise 2025 Mass Internet Exploitation Report provides security leaders, SOC analysts, vulnerability managers, and threat intelligence teams with actionable insights. Attackers are industrializing reconnaissance and exploitation. Security teams must adapt. This report provides the intelligence needed to prioritize, respond, and defend against the next wave of mass exploitation.

That is the purpose of this report is to show you the hours saved, the data aggregated, and the research methodologies laid bare. you’ll find several sections covering some of the bigger mass exploitations of 2022, also known as celebrity vulnerabilities.

This report presents multiple segments detailing various key aspects of major mass exploitations of 2023. We encourage you to view the year through the perspective of a defender, say on a security operations (SOC) team, with limitless access to GreyNoise data. From this vantage point, see how 2023 might have appeared if you had utilized our datasets* to remain at the forefront of thwarting widespread internet exploits.

In the second quarter of 2023 GreyNoise researchers observed a substantial change in the behavior of some regular internet scanning idioms. Inventory scans—where both benign and malicious actors perform regular checks for a given technology or specific vulnerability being present—significantly reduced in frequency and scale. These targeted attacks threaten to circumvent existing defense capabilities and expose organizations to a new wave of disruptive breaches. Defenders must evolve in response.
