Nmap 7.94 Released: What’s New!

The latest version of Nmap, 7.94, was released on its 26th birthday. The most significant upgrade was the migration of Zenmap and Ndiff from Python 2 to Python 3 across all platforms.

This new version of Nmap 7.94 was upgraded with more than a number of improvements, fixed some of the critical bugs, and added new Npcap, OS fingerprints, NSE scripts/libs, and other enhancements.

What is Nmap?

Nmap is a free and open-source network scanner, Port Scanner, and network Exploration Tool that supports all cross platforms, including Linux, Windows, UNIX, FreeBSD, OpenBSD, Solaris, IRIX, Mac OS X, HP-UX, NetBSD, Sun OS, Amiga, and more.

“Nmap supports Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses some packet filters), TCP ACK and Window scanning, UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct (non portmapper) RPC scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning.”

Npcap is based on the discontinued WinPcap library, but it has significantly improved speed, portability, security, and efficiency. Npcap works on Windows 7 and later Windows versions.

The new Nmap 7.94 release not only benefits Windows but also supports cross-platform with a bunch of new libraries’ performance improvements.
