  • http.request.method == GET on wireshark
  • Export Objects > HTTP > git-receive-pack
  • Create a new git repo
  • Place in the git repo
  • Open in hex editor and fix the file header to be just 'PACK' at the beginning (remove all the crap)
  • Now git unpack-objects < git-receive-pack
  • Navigate to objects folder, here there are 3 git objects:
    • a commit
    • a tree file
    • a blob file
  • Decompress the zlib blob file with: python -c "import zlib; print zlib.decompress(open('3f47cbcb3ad8e946d0aad59259bdb1bc9e63f2').read());" > flag.jpg
  • Open the file up in a hex editor and remove the first few bytes so the header is a jpeg header
  • Open it up for the flag
