hello-nemo (50pts, 128 solved) Misc & Forensics [Easy]

First look

When we open the pcap, we’re a bit overwhelmed, by the size of the file and the amount of packets.

Solving

I just searched for flag until I came to a zip file (recognized the magic bytes, PK..). We can simply extract this, by:
Right click -> Follow -> TCP Stream or Cntrl + Alt + Shift + T and then select Raw under Show and save data as -> Save as -> flag.zip.
When we now open the zip file, we see that it requires a password.
When we just simply search for password, we find dgyfogfoewyeowyefowouevftowyefg, which is our password.
Using the password, we can read the flag: DCTF{3907879c7744872694209e3ea9d2697508b7a0a464afddb2660de7ed0052d7a7}
