Hello everyone. I’m stuck in the decryption as well.

  1. Used plistutil to get flag
  2. Used IDA to get key, IV
  3. Decoded them into hex
  4. Testing out with AES using CyberChef

I can’t figure out what I’m missing or overlooking. I’d appreciate if someone could help me out.

Im using Kali Linux… trying to figure this challenge out… having trouble figuring out how to use plistutil… I did some searches and installed the libplist-utils package and libplist3, and attempted to use the same commands i found on those sites, but no matter what i type, I get “command not found” whether sudo or not.

I’m not understanding how to actually view the plist files?? Any help would be appreciated

(using kali Linux)

cd ./that directory
plistutil -i challenge.plist
