Exploits are programs designed to leverage various vulnerabilities in cyberattacks. Latest Kaspersky Security Network data reveals an increase in attacks with exploits against Linux users. The research indicates the peak was in Q4 2023, while overall trend for growth is persisting in 2024, with an insignificant decline in Q1.

Linux is gaining traction the desktop operating system market. According to Statcounter, its market share has grown, and the number of users increased. “This trend quite accurately explains the growing threat landscape we witness for Linux. In the future, the number of exploits and attacks is likely to grow even more, underscoring the vital need for installation of patches and having a reliable security solution,” says Alexander Kolesnikov, a security expert at Kaspersky. “The greatest value for exploit developers lies in vulnerabilities within software that grant control over a user’s system.”.
Critical vulnerability registrations rise over the last four years
Kaspersky recorded a 65 percent increase in the number of registered CVEs (Common Vulnerabilities and Exposures) over the last four years, from 15,000 in 2019 to 25,000 in 2023. Moreover, during the last year, researchers and companies logged critical vulnerabilities three times more frequently than the research period average. The annual average of critical vulnerabilities registrations from 2019 to 2022 was 413, which spiked to the absolute number of registrations of 1213 in 2023.
