The first step in finding a web server in a Wireshark capture pcap is to identify the Finding the IP Address of the Web Server. The next step in finding the web server engine is to analyze the protocols that are being used. The certificate issuer data is similar to that of the first example. This pre-master secret can be obtained when a RSA private key is provided and a RSA key exchange is in use. Reassemble out-of-order segments (since Wireshark 3.0, disabled by default). *, and the 0x0X indicates the TLS version - 0x01 for TLS 1.0, 0x02 for TLS 1.1, and 0x03 for TLS 1.2. The downside is that Wireshark will have to look up each domain name, polluting the captured traffic with additional DNS requests. This matches the same pattern as Dridex HTTPS C2 traffic from our first pcap. Under RHEL, konrad's answer didn't work for me because tcpdump requires root, and I only have sudo access.
