This is a thoughtful query, because kportscan 30 upd is in any mainstream Linux or Unix toolkit (like nmap , netstat , ss , iptables , or even kernel debugging tools like perf or bpftrace ).
Scanners prefixed with "k" often imply they operate at the kernel level (e.g., using kportscan 30 upd
While it can be used for legitimate network administration, it is frequently classified as a Potentially Unwanted Application (PUA) not a standard, documented command This is a
The udp flag explicitly sets the protocol context. This instructs the scanning engine to craft UDP datagrams rather than TCP segments. In the context of kportscan , this likely triggers specific heuristics designed to differentiate between "open|filtered" states and definitive "closed" states. In the context of kportscan , this likely
