CyberLab: From Zero to CTF Hacker

🌐 Who's Talking on This Network? — Network CTF #01 🔍

Think you can investigate network traffic? Let's test your packet-analysis skills!

🕵️ Your mission:

You're investigating a sample network capture (.pcap) from a controlled lab. Something unusual appears in the traffic, and you need to figure out what's happening.

🎯 Your challenges:

• Identify the IP addresses communicating with each other.

• Find which protocols are being used.

• Look for unusual connections or unexpected traffic patterns.

• Explain what additional evidence you'd need before calling the activity suspicious.

💡 Hint: Start with Wireshark's protocol hierarchy and Conversations views. Filters like dns, http, and tcp can help you narrow down the traffic.

🏆 Bonus challenge: Which Wireshark feature would you use to identify the most active communicating hosts?

⚠️ Use sample captures or traffic from networks you own or have explicit permission to analyze. A single unusual packet doesn't automatically mean an attack is happening.

🧠 Can You Solve This Linux CTF? 🔐

Think you're good at Linux? Let's test your terminal skills!

📁 Your mission:

You're investigating a Linux machine and discover a suspicious file hidden somewhere in /home.

Your goal is to find it without opening every file manually.

🎯 Challenge:

• Find hidden files and directories.

• Search for a file named secret.txt.

• Print its full path.

💡 Hint: Try combining find with the right path and filename.

🏆 Bonus challenge: How would you search for the file without showing permission-denied errors?

🧠 Can You Solve This Linux CTF? 🔐

Think you know Linux? Let's test your skills!

You're exploring a Linux machine and discover a suspicious file with unusual permissions.

🔍 Your mission:

• Investigate the file and its permissions

• Figure out why it might be a security risk

• Find a way to prove your answer in a safe lab

💡 Hint: Start with ls -la and find. Understanding Linux permissions is an essential cybersecurity skill!

🎯 Challenge: What Linux command would you use to search for files with the SUID permission bit set?
