Three cybersecurity projects that teach you more than any course or certification. Build them, and you will never look at a file, a vulnerability, or a binary the same way again.
Project one: a steganography tool in Python. Encrypt a message and hide it inside a photo, PDF, or audio file. Most people learn to use this technique or detect it. Building it is where you learn what a file actually is at the byte level.
Project two: a CVE intelligence tool that grabs security news feeds, extracts vulnerabilities, and ranks them by actual exploitation risk -- not just a static severity score. Equifax had a patch available for months. The problem was triage, not awareness. This project teaches you to solve that.
Project three: a reverse engineering lab in the browser. Compiled binary, no source code, hex viewer and disassembler built in. It does not show the answer until you get it right. Software lies. A binary does not.
