CHALLENGE DESCRIPTION
SOLUTION
Manual
We open pcap
file with Wireshark
, we can notice that there are some things look like Base64
strings, and some of them have same length.
We search tcp.len == 12
to filter all packets with length is 12 and from the hint, we sort them by time. Copy all of the data to a file and decode it with base64 -d
Auto
We can also do this
1
tshark -r myNetworkTraffic.pcap -Y "tcp.len==12 || tcp.len==4" -T fields -e frame.time -e tcp.segment_data | sort -k4 | awk '{print $6}' | xxd -p -r | base64 -d
