This repository is a collection of proof-of-concept (PoC) exploit codes demonstrating various heap exploitation techniques in the GNU C Library (glibc) across versions 2.23 to 2.43. Each PoC is a standalone C program designed to be compiled and executed to showcase a specific heap corruption technique (e.g., fastbin dup, tcache poisoning, house of spirit, etc.) under controlled conditions. The primary purpose is educational, targeting security researchers, CTF participants, and students studying binary exploitation. The architecture is organized around a build system (Makefile) that compiles version-specific exploits located in directories named after glibc versions. Each exploit is self-contained with a main function, simulating heap manipulations to achieve arbitrary memory writes or code execution. Key entry points include the Makefile for building, an interactive heap exploration tool (malloc_playground.c), and a CI workflow for automated testing across multiple environments. The repository relies on glibc, build tools, and Docker for environment setup, with a submodule providing access to multiple glibc releases. The repository exhibits strong engineering practices through its reusable components: the Makefile employs wildcard and foreach functions to manage version-specific builds without duplication; malloc_playground.c offers an interactive interface for heap analysis that can be reused in other educational contexts; and the CI workflow uses a matrix strategy to test exploits across glibc and Ubuntu versions. Actively maintained with recent commits and low technical drift, the project adapts to glibc's evolving security mitigations by updating techniques for new versions, ensuring continued relevance in heap exploitation education.
Haaukins is a cybersecurity training and Capture The Flag (CTF) platform developed at Aalborg University. It orchestrates isolated lab environments for teams, combining Docker containers and VirtualBox VMs to deliver challenges. The system is built as a set of gRPC microservices: a central daemon manages event lifecycle, team assignments, and challenge verification; a store service provides persistence; and an exercise service defines challenge configurations. Participants access labs via a web frontend (Amigo) using browser-based RDP (Guacamole) or WireGuard VPN. The daemon also handles DNS/DHCP per lab subnet, real-time scoreboards via WebSocket, and keylogging for monitoring. The CLI client (hkn) allows administrators to manage events, teams, and exercises. The architecture is modular with clean interfaces for virtualization (Docker/VirtualBox) and storage (in-memory with hooks or gRPC backend), though some components show tight coupling and aging dependencies.
This repository is a large collection of standalone Python scripts designed for the Termux environment on Android. It is marketed as an educational cybersecurity toolkit but contains functional phishing pages, credential harvesters, location trackers, camera/mic capture scripts, and a trojan for data exfiltration. The codebase also includes some legitimate utilities such as a password manager, file converter, network scanner, and backup tool. The architecture is highly fragmented: each script is self-contained with its own dependency auto-installation, Flask server, and cloudflared tunnel for public exposure. There is no shared module structure, and the code is heavily duplicated across English and Greek translations. The overall quality is low due to copy-paste patterns, hardcoded secrets, suppressed error logging, lack of testing, and reliance on external services like cloudflared. The repository poses significant legal and ethical risks due to its phishing and surveillance capabilities.
