POC :

[+] Dorking İn Google Or Other Search Enggine.

[+] Code Description: Brief script that demonstrates running valgrind and afl-fuzz on Google Chrome. (Related : https://packetstorm.news/files/id/189250/ Related CVE numbers:   ) .

[+] Using alternative commands on Windows : 

    gdb is not available by default, dumpbin from Visual Studio can be used as an alternative.

    valgrind is not supported on Windows, Dr. Memory can be used.
   
    afl-fuzz does not work on Windows directly, you can look for an alternative tool like WinAFL.
