What problem does it solve?
During internal network penetration testing, attackers often cannot directly reach intranet services due to firewalls and network segmentation. This Skill provides operational guidance for using iox, a single-binary zero-dependency port forwarding and proxy tool, to build traffic tunnels that expose internal services to the attack machine.
Core Features & Use Cases
- Port Forwarding (fwd mode): Forward a target port to an internal address in forward mode, or use reverse mode where the target connects out to the attacker when inbound traffic is blocked.
- SOCKS5 Proxying (proxy mode): Stand up forward or reverse SOCKS5 proxies so tools like proxychains and nmap can scan entire internal subnets through the compromised host.
- Encrypted Transport: Add the -k flag for TLS-encrypted tunnels to reduce traffic signature detection.
- Use Case: After obtaining a shell on a DMZ host, run a reverse iox proxy back to the attack machine, then use proxychains to RDP into an internal Windows server at 10.0.0.2 that is otherwise unreachable.
