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 been released. In the year 2023, types of vulnerabilities targeted by the attackers changed, with rates of zero-day exploitation, which rose to a ratio of 30:70 compared with N-day attacks. This trend shows that attackers now prefer zero-day exploits, which may be because they allow immediate access to systems and sensitive data before the vulnerability is known to the world.
Timing and Frequency of Exploitation
This again proves that N-day vulnerabilities are at their most vulnerable state during the first few weeks when the patch is released. Of the observed N-day vulnerabilities, 56% happened within the first month after a patch was released. Besides, 5% were attacked within just one day of the patch release while 29% attacked in the first week after release. This fast pace is something that makes the patches really important to apply to organizations as soon as possible after they are available.
Widening Scope for Attack Targets
For the past ten years, attackers have enormously widened their scope of attacks by targeting a growing list of vendors. According to the report, on this front, the count increased from 25 in the year 2018 to 56 in 2023. The widening of such a nature increases the trouble for teams, who have now encountered a significantly expanded attack surface along with the ever-increasing possibility of attacks at a number of systems and software applications.
Case Studies Exposing Different Exploits
Mandiant has published case studies on how attackers exploit vulnerabilities. For example, CVE-2023-28121 is a vulnerability in the WooCommerce Payments plugin for WordPress, which was published in March 2023. Although it had been previously secure, it became highly exploited after the technical details of how to exploit the flaw were published online. Attacks started a day after the release of a weaponized tool, peaking to 1.3 million attacks in one day. This fast growth shows how easy certain vulnerabilities can be in high demand by attackers when tools to exploit are generally available.
The case of the CVE-2023-27997 vulnerability that occurred with respect to the Secure Sockets Layer in Fortinet's FortiOS was another type that had a different timeline when it came to the attack. Even though media alert was very much all over when the vulnerability was first brought to the limelight, it took them about two or three months before executing the attack. This may probably be because of the difficulty with which the exploit needs to be carried out since there will be the use of intricate techniques to achieve it. On the other hand, the exploit for the WooCommerce plugin was quite easier where it only required the presence of an HTTP header.
Complexity of Patching Systems
While patching in due time is very essential, this is not that easy especially when updating such patches across massive systems. The CEO at Quarkslab says that Fred Raynal stated that patching two or three devices is feasible; however, patching thousands of them requires much coordination and lots of resources. Secondly, the complexity of patching in devices like a mobile phone is immense due to multiple layers which are required for updates to finally reach a user.
Some critical systems, like energy platforms or healthcare devices, have patching issues more difficult than others. System reliability and uninterrupted operation in such systems may be placed above the security updates. According to Raynal, companies in some instances even ban patching because of the risks of operational disruptions, leaving some of the devices with known vulnerabilities unpatched.
The Urgency of Timely Patching
Says Mandiant, it is such an attack timeline that organisations face the threat of attackers exploiting vulnerabilities faster than ever before. This is the report's finding while stating that it requires more than timely patching to stay ahead of attackers to secure the increasingly complex and multi-layered systems that make up more and more of the world's digital infrastructure.
