I found this yaml in the red team's repository. I searched in splunk like index="t1547.001-win"Īnd throw the commands to the answer, but nothing hits. I search Registry Run Key in this file, and found the related attack is T1547-001. I found the attack list in the red team's github repository ( atomic-red-team/atomics/Indexes/Indexes-CSV/windows-index.csv). | search WindowsAudioDevice-Powershell-Cmdlet, ProcessID I thought the words WindowsAudioDevice-Powershell-Cmdlet and ProcessID are useful to search, so I tried this with time sort. Powershell.exe -Command WindowsAudioDevice-Powershell-Cmdlet I searched the AudioDeviceCmdlets word in red team's repository, and found T1123.yml. There's 8 repositories there, and one repository is stared many. I have to search the first OSTAP related atomic test record. The answer is HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography. I tried the Repository search with the word MachineGuid, then I found Registory key in T1082.yaml. Inspired by the Hint from Alice, I checked the Atomic Red Team repository. Training 2įrom the search results from Training 1, I guess the answer is t1059.003-main t1059.003-win. The count is 14, but t1059 is tried twice, so the distinct count is 13. But I found that MITRE ATT&CK ID is like the record's pattern, and guess that I should count the txxx-main or txxx-win count. Because it was completely new to me, I wondered what number to count.

I throw given query from Alice to the Splunk search. Before that, I should train myself via seven "Training Questions". The Objective goal is answer the "Challenge Question". When I tried ID 6000, the door lock opened. Then I back to the locked door, and simulated tags by pm3 -> lf hid sim -w Kastle -fc 113 -cn I gathered other's tag information by pm3 -> lf hid readĬommand on Proxmark3 terminal. And, I guessed I have to gather the other's tag information in the castle, and open the locked door. I started the Proxmark3 terminal, and tried some commands in the CheatSheet. The essential cheat sheet was very useful for me. I've picked up "Proxmark3" item somewhere, and I could use it. Other items are unused.įrom Bushy Evergreen's hints, I guessed that this challenge is bout RFID hacking. I used 3 light bulbs, 2 nuts, and 1 candycane like this. I understood that I have to supply the white energy to all lights bulbs using items which I picked. Then, I tried ASAR tool with guide, extract the codes from this asar file. I found the asar file which mentioned in the Hints. app-64/locales/it.pak matchesīinary file. This is the PE file.įirst, I decompressed the exe file, and got many files. At last, I got North Pole: The Frostiest Place on Earth text, and this is the answer of this Objective.
MR. PREPPER LEVER ZIP
Still wrapped.! Then, I unwrap the file with zip -> tar -> xxd -> 7z -> compress'd data 16 bits. xz.2: bzip2 compressed data, block size = 900k
MR. PREPPER LEVER ARCHIVE
Package.zip: Zip archive data, at least v1.0 to extract And when base64 decode, the file format is zip.
MR. PREPPER LEVER DOWNLOAD
So, public S3 bucket is found! Then, access to the URL and download the file. Then, adding Wrapper3000 to wordlist, and exec bucket_finder.rb with wordlist, then I had the response below. After check this tool several times, I guessed that the Wrapper3000 is suspicious bucket name which noticed by the terminal comment.

I can get the list of buckets, which I specified the name in wordlist. Then, I used site to re-screw this image, and read the original letters. I got the bottom left image from the Signboard of the entry of this world.įrom hints, I guessed the screwed letters on the paper should be re-screwed and to be deciphered.
