  • Description: Can you handle APKs?
  • Difficulty: Medium

🔎 Solution​

The challenge provides us with an APK file. When dealing with APK challenges, I typically start by extracting the contents as if it were a regular ZIP archive.

After inspecting the extracted files, I discovered a file located at res/color/flag.txt, which contains the following string:

7069636f4354467b6178386d433052553676655f4e5838356c346178386d436c5f61336562356163327d

Using a text identification tool, I determined that the string is encoded in ASCII code.

By decoding the string using this tool, I was able to retrieve the flag.
