Top 12 Fuzzing Tools for Hackers

Fuzzing is a software testing methodology in which the hacker injects malformed or malicious inputs into the application. Generally, on receiving malformed inputs, the application behaves weirdly and leaks sensitive information or errors that give information to a hacker for further attacks. This whole set of test cases provides gaps in the security posture of the application.

Remember, Fuzzing is a black-box testing methodology where knowledge of implementation is not required. It helps in identifying security issues in the software.

You can perform fuzzing manually or by using software tools. Manual methods are quite slow and it will be difficult to find issues by using manual methods. Hence, it is always advisable to use software tools with manual methods. You may find issues of remote code execution and privilege escalation by using automated tools.
