For red teamers, network traffic isn’t just noise—it’s intelligence waiting to be harvested. Wireshark is a powerful tool that goes beyond basic packet captures, enabling offensive security professionals to extract critical data, evade defenses, and map networks for strategic attacks.</p><p>You Should Know: Practical Wireshark Techniques for Red Teaming</p><h2 style="color: yellow;">1. Traffic Reconnaissance</h2><h2 style="color: yellow;">Identify devices, services, and vulnerabilities by analyzing packets:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
wireshark -i eth0 -k -Y "http || dns || ftp || smb" -w recon.pcap
</pre><p>Filter for HTTP user agents, DNS queries, and SMB shares to detect weak points.</p><h2 style="color: yellow;"> 2. Credential Extraction</h2><p>Sniff plaintext credentials from protocols like HTTP, FTP, and Telnet:</p><pre data-enlighter-language="bash" class="EnlighterJSRAW">
tshark -r attack.pcap -Y "http.request.method == POST && http contains 'password'"
</pre><h2 style="color: yellow;">Extract FTP credentials:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
tshark -r ftp_traffic.pcap -Y "ftp.request.command == USER || ftp.request.command == PASS"
</pre><h2 style="color: yellow;"> 3. C2 Reverse Engineering</h2><p>Analyze Command & Control (C2) traffic to understand malware behavior:</p><pre data-enlighter-language="bash" class="EnlighterJSRAW">
tshark -r c2_traffic.pcap -Y "tcp contains 'payload' || http contains 'beacon'"
</pre><h2 style="color: yellow;">Detect beaconing intervals:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
tshark -r malware.pcap -T fields -e frame.time -e ip.src -e ip.dst -Y "tcp.port == 443"
</pre><h2 style="color: yellow;"> 4. Network Topology Mapping</h2><h2 style="color: yellow;">Discover network structure using ARP, DHCP, and LLMNR/NBT-NS:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
tshark -r network.pcap -Y "arp || dhcp || nbns"
</pre><h2 style="color: yellow;">Extract IP ranges and hostnames:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
tshark -r traffic.pcap -Y "dhcp.option.dhcp == 53" -T fields -e ip.src -e dhcp.option.hostname
</pre><h2 style="color: yellow;"> 5. Bypassing IDS/IPS with Packet Fragmentation</h2><h2 style="color: yellow;">Evade detection by fragmenting malicious traffic:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
nmap -f --mtu 24 <target> Fragmented scan
</pre><h2 style="color: yellow;">Craft custom fragmented packets with Scapy:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
from scapy.all import
packet = IP(dst="target.com", flags="MF", frag=0)/ICMP()/("X" 600)
send(packet)
</pre><h2 style="color: yellow;"> 6. Extracting NTLM Hashes for Lateral Movement</h2><h2 style="color: yellow;">Capture SMB/NTLMv2 hashes for relay attacks:</h2><pre data-enlighter-language="bash" class="EnlighterJSRAW">
tshark -r smb_traffic.pcap -Y "ntlmssp.ntlmv2_response" -T fields -e ip.src -e ntlmssp.ntlmv2_response
</pre><h2 style="color: yellow;"> What Undercode Say</h2><p>Wireshark is an indispensable tool for red teamers, enabling deep network analysis, credential harvesting, and stealthy operations. Mastering these techniques ensures you stay ahead of defenders, turning raw traffic into actionable intelligence.</p><h2 style="color: yellow;"> Expected Output:</h2><ul><li>Extracted credentials from packet captures.</li><li>Mapped network topologies from passive recon.</li><li>Detected C2 channels for threat hunting.</li><li>Successfully bypassed IDS/IPS with fragmentation.</li></ul><h2 style="color: yellow;"> Prediction</h2><p>As network defenses evolve, red teamers will increasingly rely on advanced Wireshark techniques to bypass AI-driven detection systems, making real-time traffic analysis a critical skill in offensive security.</p><h2 style="color: yellow;">References:</h2><p>Reported By: <a href="https://www.linkedin.com/posts/dharamveer-prasad-64126a231_wireshark-for-red-teamers-activity-7325195327202836480-FuSy" target="_blank" rel="noopener">Dharamveer Prasad</a> – Hackers Feeds<br />
