    If we are doing a CTF or performing Malware analysis with Wireshark, we usually need to extract files from PCAPs at some point. In this video, we will look at how to do it.

    How does one get into packet capture analysis? Also it appears that the Wireshark cert is not high in demand in job postings. Curious of your thoughts on that.

      Hi CHris!I alway looking for something about packet capture analysis work on with wireshark !

    • @ChrisGreer
      @ChrisGreer  3 года назад +4

      Hello - how does one get into it? I guess several ways... if you are in netops, secops, devops, just download it, install, and get to capturing. Learn what each packet means, one at a time. Start slow and get more complex. Watch videos like these ones on my channel to get a running start, and then just do it!
      Certs? I had the WCNA for some time. It goes into several aspects of the analyzer that are good to know. Do you need it for a job? Probably not. I've known some amazing packet analysts that never got it.
