Cyber threat overview 2024
This document provides an overview of the past year, which has been marked by ever-increasing efforts on the part of attackers to destabilize the cyber ecosystem and compromise critical information systems.
In line with the previous years, ANSSI estimates that attackers associated with the cybercriminal ecosystem and reputedly linked to China and Russia are three of the main threats facing both critical information systems (ISs) and the national ecosystem as a whole.
This past year was marked by the hosting of the Paris Olympic and Paralympic Games which, by virtue of the event’s media exposure and attack surface, presented golden opportunities for attackers. In this context, ANSSI has observed attacks aimed at extortion and strategic espionage, as well as a majority of attacks conducted by hacktivist groups for destabilisation purposes. None of these attacks have had a notable impact on the smooth running of the Games.
The year was also marked by the number and the impact of vulnerabilities affecting information systems’ security edge devices: over half of ANSSI’s cyberdefense operations – which make up the highest level of the Agency’s engagement in incident response – were brought about by the exploitation of vulnerabilities on such devices.
