by DrQuark

DESCRIPTION

0xDarkArmy has 1 social account, and DarkArmy uses the same name everywhere. Hint: the front page of the internet flag format: darkctf{}

WRITEUP

So I used sherlock here to find all the linked social media accounts of 0xDarkArmy. image

After running sherlock , i found various results but the result which was intriguing for me was the reddit one as in the description of challenge , the hint which was provided was “ The front page of internet “ and we know that reddit is the front page of internet . so i went to this subreddit r/0xDarkArmy

image

Here I saw a comment which redirected me to a user account on which , one of his post was marked as spoiler and contained a QR code .

image

When I scanned this Qr Code , it was a onion website link , so I opened this link in tor and found the first half of the flag

image

Next part of the flag was in the request methods as flag header
