Use the file command in Linux to confirm it is truly a 7z archive. 2. Archive Inspection
If you'd like to dive deeper into a specific file found inside the archive: Tell me the you see inside. Share any weird extensions (like .out or .dat ).
Run sha256sum NNSMFIS15.7z to ensure the file hasn't been tampered with.
In forensics challenges like this, the answer is rarely in the file content itself. Look for:
Extract metadata, recover deleted files, or find hidden "flags" within the archive. 🛠️ Recommended Analysis Steps
Run strings NNSMFIS15.7z | grep "NCL" to search for plain-text flags inside the compressed data. 💡 Common "Flag" Locations
Use 7z l NNSMFIS15.7z to view filenames without extracting.
