My output keeps showing a timeout

[AndyElGang]

When I use the command afl-fuzz -i C:\Users\andye\Desktop\inputs -o C:\Users\andye\Desktop\output -t 25000+ -Y -D C:\Users\andye\Desktop\DynamoRIO\bin64 -- -fuzz_iterations 5000 -covtype edge -nargs 1 -target_module example.exe -- example.exe @@ I get this output no matter how hard I try to fix it, can someone tell me what's going on? I'm pretty new to fuzzing and literally don't know why it still times out

The timeout error isn't necessarily a timeout, it can also be received due to incorrect parameters, such as is likely the case here. For example

• you use both -Y flag for static instrumentation and -D for Dynamorio instrumentation. You should only use one. I actually recommend using TinyInst instrumentation for first-time users. You can see examples at https://github.com/googleprojectzero/winafl/blob/master/readme_tinyinst.md (note that some flags have different names in TinyInst and other modes)
• You are missing a -target_method flag.

this is my new command, but it still doesn't work, and yes I prefer using -Y afl-fuzz -i C:\Users\andye\Desktop\inputs -o C:\Users\andye\Desktop\output -t 25000+ -Y -- -target_method main -fuzz_iterations 5000 -covtype edge -nargs 1 -target_module example.exe -- example.exe @@

[ifratric]

For -Y (static instrumentation) please read https://github.com/googleprojectzero/winafl/blob/master/readme_syzygy.md Did you successfully prepare and instrument your target as described in that readme?

[AndyElGang]

Nevermind, it requires me to switch to 32 bit because it only supports that, if I use DynamoRIO, do I need to implement anything? Or as it suggests it can do it in real time

[ifratric]

Both DynamoRIO and TinyInst are dynamic binary instrumentation solutions that instrument the target as it runs and support both 32- and 64- bit targets.

Do you know what this assert failure means? And yeah if ask about my code implementation it is this one and this is the command I used = afl-fuzz -i C:\Users\andye\Desktop\inputs -o C:\Users\andye\Desktop\output -t 25000+ -D C:\Users\andye\Desktop\DynamoRIO\bin64 -- -target_method main -fuzz_iterations 5000 -covtype edge -nargs 1 -target_module example.exe -- example.exe @@

#include <iostream>
#include <string>

int main() {
    std::string userInput;

    // Prompting user for input
    std::cout << "Enter something: ";
    std::getline(std::cin, userInput); // Allowing spaces in input

    // Printing the input
    std::cout << "You entered: " << userInput << std::endl;

    return 0;
}

can someone give me a step by step i'm actually lost, like based on my code can someone compile it and show me how it's done?

[AndyElGang]

Nevermind I just copied the exact command of another person and adapted it to my file and it works fine now
