As has been mentioned, many software-developing companies have rigorous patch management, and therefore they always update their software whenever a vulnerability is discovered. This frustrates hacking efforts targeted at exploiting vulnerabilities that software developers have already patched. As an adaptation to this, hackers have discovered zero-day attacks. Zero-day attacks use advanced vulnerability discovery tools and techniques to identify vulnerabilities that are not yet known by software developers. Some of the commonly used tools and techniques implemented by hackers to find zero-day vulnerabilities are as follows.
This involves the recreation of a system by the hacker in an attempt to find a vulnerability. Through fuzzing, hackers can determine all the safety precautions that system developers have to put into consideration and the types of bugs that they had to fix while making the system. An attacker also has a higher chance of creating a vulnerability that can...
