Nmap (Network Mapper) is a network scanner used to discover hosts and services on a computer network by sending packets and analyzing responses.

Nmap provides many functions for probing computer networks, including host discovery and service and operating system detection. These capabilities can be extended through scripts to provide more advanced service detection, vulnerability detection, and other capabilities. Nmap can adapt to network conditions during scanning, including latency and congestion.

Nmap started out as a Linux tool and has since been ported to Windows, macOS and BSD.

Nmap 7.93 is officially released with the following updates:

  • This release commemorates Nmap’s 25th anniversary, and it all started with this article by Fyodor on September 1, 1997: https://nmap.org/p51-11.html.

  • Fix a bug where Nmap could not discover interfaces on Linux when no IPv4 address was configured
  • Update Nmap output DTD to match actual output as added in Nmap 7.90<hosthint>element
  • Fix newtargets support: since Nmap 7.92, scripts cannot add targets during script prescan phase
  • The scripts dhcp-discover and broadcast-dhcp-discover now support setting a client identifier
  • The script oracle-tns-version does not report correctly for Oracle 19c or newer
  • The script redis-info crashes or produces inaccurate client connection and/or cluster node information
  • Nmap and Nping fail to get system route on FreeBSD
  • The script ipidseq was broken by calling an unreachable library function
  • Support for EC encryption is not properly enabled if Nmap is compiled with OpenSSL in a custom location
  • Stopped creating Nmap win32 binaries
  • Fix TDS7 password encoding in mssql.lua
  • Replacing obsolete CPEs for IIS with newer identifiers
