CSAW CTF 2013 - Misc50 (Networking 2)

Networking 2 - 50 Points
networking.pcap
networking.pcap.process

Another PCAP challenge. Nothing interesting in the packet capture, let's run file on networking.pcap.process:

$ file networking.pcap.process
networking.pcap.process: AIX core file 32-bit, c05be5e08ea163007af5144}.exe- 64-bit, *

Hmm.. okay. Let's run strings on it:

$ strings networking.pcap.process | less 
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
flag{f9b43c9e9c05be5e08ea163007af5144}.exe^L
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
flag{f9b43c9e9c05be5e08ea163007af5144}.exe
...
...

Easy, isn't it?
