Capture The Flag - CTF

All the challenges you will find on this site are no official challenges hosted for a competition, instead they are staticly hosted for anyone to try their skills.

If this is your first CTF then most likely, you'll find these challenges to be very exciting. Or else if you are already an intermediate CTF challenge solver and are experienced in penetration testing, binary reversing, information gathering and so on, then some of these might be too easy for you!

What are Capture the Flags [ CTFs ] :-

The CTFs are special hacking competitions, if you go in detail, they are quite broad, but I believe they are most likely categorized into :-

Jeopardy Style
Attack and defense

In this site we will be covering only the Jeopardy-style CTFs.

Jeopardy-style CTFs can have many questions of different categories ranging from Web Analysis, Forensics, Cryptography to even Binary Reversing.

So you will be given different tasks [ questions ], from those you must find the flag, you might take help of the hints given along with each question. The general flag format will be:

VulnX_CTF{FLAG_HERE}

The 'FLAG_HERE' is replaced with a different flag according to each question. Find the flag and check the answer! You can of course inspect the HTML to get the flag without efforts, but if you really think that you can solve the challenges without cheating, give them a try!
To help you get started with solving CTFs we decided to make the first few challenges quite simple.
