```from scapy.all import *
r = rdpcap("data.pcap")
flagL = []
for i in range(0, len(r)):    if ICMP in r[i]:		print 'OK'		if not "ICMP 10.136.255.127" in r[i][ICMP].summary():			continue		print r[i]		d = str(r[i]).encode('hex')		if d not in flagL:			flagL.append(d[68:70])f = open('flag.gif', 'w')f.write(''.join(flagL).decode('hex'))f.close()```
You get a flag.gif showing `flag{we_ride_at_midnight}`
