4. It is said that MD5 encryption is very secure, really?

5. Racial discrimination: Xiao Ming visited a website today, but he didn't allow Chinese people to visit! It was a pit, so Xiaoming decided to go in and have a look!
Firefox access, burp capture
Try to add a referer: Foreigner finds it impossible; If language is found, delete the CN related language and put the package.
6.HAHA browser
To modify user agent
7. Where is the key?
Capture and replay found key.
8.key can't be found again.
Two jumps, grab the bag respectively.
Access key_is_here_now_.php get key
9. Pretend to be a login user: Xiao Ming comes to a website and still wants a key, but he can't log in anyway. Can you help him log in?
If the cookie is found to be login = 0, it can be modified to 1.
10. Compare numbers.
The title is a number input box, which limits the length of numbers. Open burp and change the parameter to a large enough value.
11. Local temptation: Xiaoming scans his beloved Xiaohong's computer and finds that port 80 is open, but when Xiaoming goes to visit, he finds that only local access is allowed, but his beloved Xiaohong dare not let this strange Xiaoming touch her computer, but Xiaoming really wants to know what secret is hidden in port 80 of Xiaohong's computer?
You need to access port 80.
emmm
12. Don't let you visit: Xiao Ming designed a website. Because he was always attacked by hackers, this time he put the background in a place where no one could find it.
I started accessing robots after I failed to capture the package and modify the parameters Txt, sure enough.
