CDK (Container Docker/Kubernetes Exploitation Toolkit) is a Go-based CLI penetration testing tool designed for container and Kubernetes environments. It evaluates security posture by running extensive checks against container runtime configurations, K8s API permissions, cloud metadata, and kernel exploit possibilities. It then executes a plethora of exploits covering container escape (cgroups, mount, eBPF, runc/containerd CVEs), K8s credential access (secrets, configmaps, tokens), persistence (backdoor daemonsets, cronjobs, shadow API server), privilege escalation (service account token theft, CVE-2026-31431), and remote control (reverse shells, kubelet exec). The binary bundles stripped-down versions of common tools (kubectl, netcat, vi, etc.) for post-exploitation use. The architecture follows a plugin pattern where exploits register themselves via init(), and evaluation uses a category-based check system. The codebase shows signs of organic growth with some legacy cruft (deprecated auto-escape task, commented-out code, future-dated CVEs) and moderate technical debt (global mutable state, panics, outdated Go idioms), but remains functional and actively maintained for penetration testers and security researchers.
DuplexSpyCS is a full-featured Remote Access Trojan (RAT) command-and-control (C2) framework written in C# (.NET WinForms). It consists of a server-side management console and multiple payload variants (winClient48, winClient48DLL, Tipoff, etc.) that provide comprehensive post-exploitation capabilities: file manager, remote desktop, keylogger, webcam/microphone streaming, registry editor, process/task manager, remote shell (including xterm via WebView2), SOCKS5 proxy, and a plugin system for credential theft (Chrome, Edge, Firefox, MobaXterm). Communication uses a custom binary protocol (clsDSP) over TCP, TLS, or HTTP with RSA-AES hybrid encryption. The payloads employ persistence via registry/startup, UAC bypass, process injection (APC, EarlyBird, CreateRemoteThread, etc.), and fileless execution. The codebase is extensive but exhibits significant code duplication across payload projects, many incomplete or stub features, and outdated dependencies (AForge, NAudio, SharpPcap). It is explicitly designed for offensive security research and learning, but carries high risk of misuse.
