How to search in wire shark using CBL's detection information summary?

Example: Destination IP : n/a Destination port: 447 Source IP : (Prefer not to disclose) Source port: 56596 C&C name/domain: n/a Protocol: TCP Time: Mon Aug 17 09:39:49 2020 UTC

You might start with Statistics->Conversations or Statistics->Endpoints to look for matches.
A display filter of tcp.srcport==56596 && tcp.dstport==447 would match the example.
There is a chance it might match more than one conversation if the source port is reused. The Expert Information screen in Wireshark will show port reuse in the capture.
