Ringzer0CTF – Web – Headache


Ringzer0CTF – Web – Headache

Objective:
Get that flag son

Solution:

So this challenge is called headache and we get this as a hint
Answer is closer than you think!

So lets look at the response header to see what we see.

I loaded the Yet Another REST Client into my chome and pointed it at the challenge.

I had to do some research on REST because I wasn’t too familiar with it.
SO I loaded up the challenge in YARC and under response headers we see the flage

HacktheBox - Retired - Frolic Recon Let's start out with a threader3000 scan Some interesting results here Port 22 and 445 aren't uncommon… but 1880 and 9999 are..

RingZero CTF - Forensics - Who am I part 2

RingZero CTF - Forensics -  Who am I part 2 Objective: I'm the proud owner of this website. Can you verify that? Solution: Well it took me a bit to figure this one out. I tried looking at the whois records for ringzer0ctf.com I tired looking at the DNS records for the site. I even looked in the Certificate for the site. Then I thought a little be more about the question. It's not asking how I can verify who own the site. It wants me to verify the owner themselves. Luckily at the bottom the page we see who is listed as on the twittter feeds @ringzer0CTF and @ MrUnik0d3r lets check if we can find the PGP for MrUniK0d3r online. I googled PGP and MrUn1k0d3r The very first result is his PGP  keybase.txt with his PGP at the bottom of the file is the flag FLAG-7A7i0V2438xL95z2X2Z321p30D8T433Z
