x64 Assembly ICMP Sniffer Built Without libc for Low-Level Packet Analysis
A developer created an ICMP sniffer in x64 Assembly using only Linux syscalls, rejecting standard C libraries. The tool captures raw ICMP packets, manually strips IPv4 and ICMP headers, and converts binary IP data to ASCII via a custom integer-to-string engine. The project aims to provide a foundation for understanding hardware behavior during security auditing and low-level software analysis.
Meridian48 take
While niche, this project demonstrates the extreme end of low-level programming and could be useful for security researchers seeking to understand raw packet handling, but its practical application is limited.
