There has been unprecedented exploitation by attackers of vulnerabilities in the software, Mandiant announced. According to the newly released report of the Mandiant cybersecurity firm, after an analysis of 138 exploits published in 2023, on average, in five days an attacker already exploits a vulnerability. Because of this speed, very soon it has become paramount for organisations to make their system updates quickly. The study, published by Google Cloud bloggers, shows that this trend has greatly reduced the time taken for attackers to exploit both unknown vulnerabilities, known as zero-day, and known ones, called N-day.
Speed in the Exploitation Going Up
As indicated by Mandiant research, the time-to-exploit, which is a statistic indicating the average number of days taken by attackers to exploit a discovered vulnerability, has been reducing rapidly. During 2018, it took nearly 63 days for hackers to exploit vulnerabilities. However, in the case of 2023, hackers took merely five days for exploitation. This shows that the attackers are getting more efficient in exploiting those security vulnerabilities before the application developers could patch them satisfactorily.
Zero-Day and N-Day Vulnerabilities
The report makes a distinction between the zero-day vulnerabilities, being the undisclosed and unpatched flaws that attackers would exploit immediately, and N-day vulnerabilities, which are already known flaws that attackers aim at after patches have already be
