ABYCTF: Sovereign Cyber Range & CTF Arena
Ethiopia’s sovereign cybersecurity training range and capture-the-flag arena featuring live Jeopardy challenges, dynamic attack-defense battlegrounds, and automated binary exploitation sandboxes.

Active Range Targets & Flag Verification
Obelisk Buffer Smashing
Smash the stack on an ARM64 microservice binary to hijack the return instruction pointer and pivot into a ROP gadget chain bypassing ASLR & stack canary.

Engineered for Real-World Practitioners
Dynamic Attack-Defense Arena
High-Stakes Live Red vs Blue BattlegroundsTeams defend vulnerable sovereign service nodes while simultaneously auditing, weaponizing, and firing zero-day exploits into competing enemy server towers in real time.
Ephemeral Containerized Sandboxes
Isolated MicroVM Environments per ChallengerEvery challenger receives a dedicated, kernel-isolated Firecracker microVM instance with gRPC health-checking and dynamic root flag rotation.
Low-Level Binary Exploitation
Real-World Architectures (ARM64, x86_64, RISC-V)No web-quiz fluff. Challenges simulate actual operational scenarios: kernel driver heap corruptions, SCADA PLC protocol exploits, and hypervisor breakouts.
Real-Time Telemetry & Scoring Engine
Cryptographic Anti-Cheat Flag VerificationZero-knowledge HMAC validation prevents flag sharing. Automated SLA checks test the availability of contested services every 60 seconds.
