The release of Nmap 7.92 network security scanner is available, designed to conduct a network audit and identify active network services. The new version fixes the Fedora project's concerns regarding incompatibility with the open source criteria of the NPSL license (based on GPLv2), under which the Nmap code is distributed. In the new license option, the mandatory requirement to purchase a separate commercial license when using code in proprietary software has been replaced with recommendations for using the OEM licensing program and the possibility of purchasing a commercial license if the manufacturer does not want to open the code of its product in accordance with the copyleft license requirements or intends to integrate Nmap into products , incompatible with the GPL.
The release of Nmap 7.92 is dedicated to the DEFCON 2021 conference and includes the following notable changes:
- Added "--unique" option to prevent scanning the same IP addresses multiple times when different domain names resolve to the same IP.
- Support for TLS 1.3 has been added to most NSE scripts. Advanced features such as SSL tunneling and certificate parsing require at least OpenSSL 1.1.1.
- The composition includes 3 new NSE scripts to provide automation of various actions with Nmap:
- nbns-interfaces to obtain information about the IP addresses of network interfaces through a call to NBNS (NetBIOS Name Service).
- openflow-info to get information about supported protocols from OpenFlow.
- port-states to list network ports for each stage of the test, including "Not shown: X closed ports" results.
- Improved accuracy of UDP probe requests (UDP payload, protocol-specific requests that result in a response rather than ignoring the UDP packet). New checks added: TS3INIT1 for UDP port 3389 and DTLS for UDP 3391.
- Redesigned code for parsing SMB2 protocol dialects. The speed of the smb-protocols script has been improved. SMB protocol versions are aligned with Microsoft documentation (3.0.2 instead of 3.02).
- Added new signatures to detect network applications and operating systems.
- The capabilities of the Npcap library for capturing and substituting packets on the Windows platform have been extended. The library is being developed as a replacement for WinPcap, built using the modern Windows NDIS 6 LWF API, and demonstrates higher performance, security, and reliability. The Npcap update in Nmap 7.92 brings support for Windows 10 on ARM-based systems, including Microsoft Surface Pro X and Samsung Galaxy Book G devices. Support for the WinPcap library has been dropped.
- Windows builds have been migrated to use Visual Studio 2019, Windows 10 SDK, and UCRT. Ended support for Windows Vista and older versions.
