The Necromancer Challenge is an interesting vulnhub box with 11 flags in various disciplines.
It starts of with network monitoring via wireshark and continues with simple bas64 decoding and some hash/ password cracking.
The challenge offers a lot to play around including steganography, cracking, binary exploitation and reversing. There’s even a little web hacking involved, so there’s something for everyone.
Enjoy the full challenge in the playlist posted above.
