The first-resort connectivity duo every analyst and admin reaches for:
ping— sends ICMP Echo Request to confirm host reachability and measure round-trip latency / packet loss.traceroute(Linux/macOS, UDP by default) andtracert(Windows, ICMP) — maps the L3 path hop-by-hop, exposing routing loops, asymmetric paths, and where packets are being dropped.
During an incident these are used to confirm whether a victim host is alive, whether outbound to a suspected C2 IP is reachable, and to spot anomalous routes that may indicate hijacking or transparent proxying.
