Editing Operational Security (OPSEC) (section)

== <span id="network-obfuscation"></span>🧬 Network Obfuscation ==

Network obfuscation conceals origin, protocol characteristics, and traffic intent by modifying how data is routed, shaped, and fingerprinted across networks. Effective obfuscation resists correlation, attribution, and detection by passive and active network monitors.

! Technique !! Description !! Usage
|-
| IP Masking || Obscure source IP using chained tunnels and geo-dispersed exits. || <code>protonvpn-cli connect --tor</code><br><code>torsocks curl ifconfig.me</code><br><code>proxychains nmap -Pn target</code>
|-
| TLS Camouflage || Alter TLS client fingerprints to evade JA3/SNI/ALPN-based detection. || <code>go run main.go -utls</code><br><code>mitmproxy --tls-insecure</code><br><code>obfs4proxy</code>
|-
| DNS Hygiene || Prevent passive DNS leaks or upstream correlation. || <code>cloudflared proxy-dns</code><br><code>dnscrypt-proxy -config dnscrypt-proxy.toml</code><br><code>unbound -d</code>
|-
| Traffic Shaping || Mask traffic timing, size, and frequency to mimic benign services. || <code>obfsproxy --data-length 1500</code><br><code>tc qdisc add dev eth0 root netem delay 250ms</code><br><code>tor --pluggable-transports</code>
|-
| Protocol Obfuscation || Encapsulate data in widely used protocols to avoid filtering. || <code>meek-client --url=https://cdn.example.com/ --front=cdn.example.com</code><br><code>hysteria -c config.yaml</code><br><code>tunslip -s /dev/ttyUSB0 192.168.0.1</code>
|-
| Decoy Generation || Generate plausible non-malicious traffic alongside operational traffic. || <code>iodine -f -P secret 10.0.0.1 my.dnstunnel.server</code><br><code>curl https://example.com & disown</code><br><code>wget https://cdn.jsdelivr.net/lib.js</code>
|-
| Timing Randomisation || Avoid predictable beaconing intervals. || <code>sleep $((RANDOM % 300)) && ./beacon</code><br><code>cron "*/15 * * * *" /usr/bin/fetch</code><br><code>python jitter.py</code>
|-
| Layered Routing || Route traffic across logically and geographically segmented layers. || <code>ssh -L 9050:localhost:9050 vps1</code><br><code>torify curl http://hidden.onion</code><br><code>proxychains ssh vps2</code>
