tshark -r hack.pcap -T fields -e http.request.full_uri|tr -s '\n'|grep flag > log
Get blind results
import re with open('log') as f: tmp = f.read() flag = '' data = re.findall(r'=(\d*)%23',tmp) data = [int(i) for i in data] for i,num in enumerate(data): try: if num > data[i+1]: flag + = chr (num) except Exception: pass print flag
