Hello. I’m Sloane. I’ll do the CTF named as Corridor from tryhackme.com. The room level is easy. The room is created by tryhackme, JohnHammond, cmnatic and timtaylor.
I started running rustscan.
The only open port is 80.
I browsed the ip address. And I was greeted with an empty corridor.
Lets inspect the page. I checked the page source first. There are a lot of links and numbers and hashes.
I’ll check the links firstly. This is the first link:
This is the page source of the first link.
This is the second link. It looks same with the previous one.
And the page source of it:
Other links were no different than these. I wanted to use crackstation.net to try to crack these hashes. And luckily it worked!
I cracked all of them one by one. The result were numbers: 1 to 13.
These are md5 type of hashes. And the numbers are representing a different place. So I’ll create hashes with other numbers. ie. 14. And then try to navigate to that address. Maybe I can discover a place that I’m not supposed to be in.
I tried a few numbers but they didn’t work. So then I thought it maybe 0. I created a hash with 0.
I navigated to that address. And it worked successfully.
That was all for this room. Thank you for reading!
