We are given a pcap file that we can open up in wireshark. Looking through it, it's a bunch of TLS encrypted traffic. A simple string search for sdctf brings up too many results to be useful off the bat, and searching for flag yields nothing. So, doing some simple TCP and TLS stream follows you can find the relevant html. Another approach is to dump all the http objects. Doing a strings on all of the exported objects also yields the following html:

```html
