If the game mimics real-world Nmap behavior, "not working" might actually be a tactical obstacle:

binary might be corrupted or hijacked by another player. In this case, use CodeEditor.exe -code nmap to recompile the tool yourself. for other tools in Hacker Simulator?

In the hacker simulator world, the -sS (SYN stealth scan) is the cool kid on the block. But creating raw SYN packets requires raw socket permissions, which only the root user (or sudo) has. Without root, Nmap falls back to the -sT (TCP connect scan), which is slower and more detectable.
