But while zero days used to be fairly rare, they are now becoming increasingly prevalent.

However, the expertise and resources required have previously limited their use.
Several factors are contributing to this rise.
These are often quicker and easier for attackers to exploit compared to more complex vulnerabilities like memory corruption flaws.
For example, vulnerabilities in Barracuda ESG and Fortra GoAnywhere MFT arose from command injection issues.
Similarly, improper authentication issues have been central to many attacks on data pipe edge devices.
Edge devices present attractive targets due to their critical role in managing data flow and access.
Notably, 36% of widely exploited vulnerabilities occurred in web connection perimeter technologies.
Fortunately, there are multiple steps organizations can take to improve their resilience against these threats when they appear.
The tried-and-true layered security strategy is key to mitigating risk.
However, the growing prevalence of zero-day attacks means organizations must implement any missing controls urgently.
Alongside this, regular patching and robust vulnerability management are essential.
Closing off new exploit paths as soon as fixes are available will shrink the opportunity for a potential attack.
Addressing other known vulnerabilities in the system will also mean fewer options are available for attackers.
Finally, organizations must also be ready to act quickly when an attack does occur.
Its not only important to have MFA implemented throughout the organization, that implementation must also be properly enforced.
There is no time to waste.
