Wireshark 3.2.7 was released with a fix for security vulnerabilities and an updated version of Npcap & Qt. Wireshark is known as the world’s most popular network protocol analyzer. It is used for troubleshooting, analysis, development, and education.

It is used by network administrators to troubleshoot network and by the security, analyst to examine the packets. It is a widely used tool in organizations.

Wireshark 3.2.7

With the new, the Windows installers now ship with Npcap 0.9997 & Qt 5.12.9.
