Help to extract PNG from pcap



I need help to try and extract a file from this pcap, At first I thought there was a PNG in there, and it's got metadata from Photoshop, but I can't see the first hex bytes of a PNG file in the items that Wireshark extracted for me.

In plaintext, I would like help with:

  1. If there is an image in there, can it get extracted? Also I would appreciate some comments/instructions how it can be done as I'm not able to. Got to keep learning!
  2. If no image, what file is it?

Unless you make the file publicly accessible, we can't assist you.

Sorry, new to cloudshark. It should be public now

One Answer:


The file magic 'ab cd 98 76' lead to a single hit on GitHub (, so it seems a Weiyun API related format. The involved IP address seems to support this observation.
