    We are looking for a freelancer who is an expert at analyzing packets obtained from TCPDUMP. We run an application that is prone to online exploits. We have identified the packets sent by the exploiter but need someone to help configure or install some sort of defence on our server to prevent these exploits from being sent to our application. I have heard about Wireshark but maybe there are some other ways to secure our server to prevent these exploiters. We must block certain packets from being sent to our server to solve this issue. We can discuss more on chat but you must be very familiar with TCPDUMP and packets (Hex)

    We need a packet capture for the Uber app on Android. The phone will likely need to be rooted (although there are VPN options for getting a tcpdump). We recommend all other apps closed to reduce "noise". We only need the Uber app opened and then a request for a ride and the very initial mapping (say about 1 minute of data). All we need is the packet capture in a standard PCAP file (e.g. can be opened with Wireshark).
