🔴 NEXUS WARGAME v1.1.2 — Operation: Zero Day

A hardened terminal-based cybersecurity wargame designed to simulate real-world attack workflows.

---

🚀 Latest Update — v1.1.2 (Integrity & Stability Upgrade)

This update strengthens the internal reliability and security of the system.

🔒 Core Improvements

• State Integrity Enforcement

  • Added checksum validation to prevent corrupted or tampered progress data

• Execution Safety Guards

  • Protected destructive operations (rm -rf) with strict path validation

• Cross-Platform Time Handling

  • Replaced non-portable date -d usage
  • Ensures consistent timing across Termux and Linux systems

• Signal Handling (Stability)

  • Added SIGINT (Ctrl+C) trap
  • Prevents corruption during forced exits

---

🧠 Why This Matters

• More stable execution
• Reduced risk of corruption
• Stronger anti-tamper behavior
• Reliable performance across environments

---

⚠️ Note

This update does not add new levels.
It reinforces the core engine for future upgrades.

⚡ Quick Start

git clone https://github.com/RootLogicDev/nexus-wargame
cd nexus-wargame
bash wargame.sh

⚡ Overview

NEXUS WARGAME is a 20-level offensive security training environment designed to force real operator thinking.

No hand-holding. No predictable puzzles.

You will:

• Enumerate systems
• Extract hidden credentials
• Decode and analyze data
• Chain commands into solutions
• Operate under pressure

---

🧠 Why This Exists

Most beginner wargames teach commands.

NEXUS trains:

• Decision making under noise
• Pattern recognition
• Tool chaining
• Realistic problem solving

---

🎯 Skills Covered

• Linux enumeration
• File analysis & identification
• Log parsing & pattern extraction
• Encoding/decoding (Base64, ROT13, binary artifacts)
• Privilege escalation concepts (SUID, cron, env leaks)
• Networking basics (Netcat, local services)
• Command pipelines (grep, cut, sort, uniq)

---
