Holiday Hack Challenge is a CTF challenge organized by SANS and Counter Hack during Christmas each year. This year the CTF was named “KringleCon 4: Jack’s back”.
It had total 13 objectives completing which one would reveal the narrative and win the CTF.
These objectives skill tested various significant areas of penetration testing – namely Active directory attacks, Cryptographic attacks, SQL injection, Server Side Request Forgery, Network Packet analysis to name a few and something very new – FPGA programming!
As you progressed, the difficulty level of the objectives increased.
It was a mind-numbing and awesome experience to complete all those objectives.
Below is the write-up of those objectives including the answers.
