Assignment

Det er nissen der står herude og banker på.

You get 2 files;

  • banke-paa
  • banke-paa.pcapng

the first file is an elf-file, so we try to run it ./banke-paa [kodeord [ip adresse]

The pcap files contains a lot of icmp packets, probably references by the "banker" part of the assignment. we know that flags start med nc3{ so we try that towards 127.0.0.1 which is the ip address of the icmp packets

it spits out

Knock: 31357
Knock: 31415
Knock: 31528
Knock: 31361

which fits with the first 4 icmp packet, ports. - we are on to something. Brute force to find the correct port and move on

./banke-paa 'nc3{julemanden banker aldrig paa!}' 127.0.0.1

Flag

nc3{julemanden banker aldrig paa!}
