Questions 3

Need help? Ask your question and get hints!

How long does it take to run brute force for this problem?

I have a question.

<script>I tried decrypting the code that was embedded in the tag, but I don't know how to do a preview after that lol.

I have a question about running a file.

Is this a reversing issue? I don't know how to run it.. I only solved the problem of analyzing the exe file by putting it in the debugger I'm new to this type, what should I do?
