Nmap
Operation Shadow Recon
Story:
In the digital shadows, you are known as "Shadow", a highly skilled hacker-for-hire. A secretive underground client, "The Black Fox," has enlisted your expertise for a high-stakes mission. Their target? A fortified corporate network rumored to be concealing classified intelligence. Your objective: infiltrate their defenses and uncover vulnerabilities without leaving a trace.
Armed with Nmap, the ultimate reconnaissance tool, you must scan their systems, analyze security gaps, and relay critical findings. Each challenge will test your ability to wield Nmap’s most powerful flags. Deciphering the correct flag is the key to progression.
With 20 challenges ahead, every step sharpens your edge in cyber warfare. Successfully completing them all will grant access to Black Fox’s hidden data vault, where the ultimate prize awaits. Failure is not an option—stealth, precision, and mastery of Nmap are your only allies in this covert operation.

Are you ready to begin the mission?
Challenge 1.
The First Scan – SYN Recon
The Black Fox wants you to stealthily scan a target without making a full connection. What flag do you use?
Challenge 2.
Noisy TCP Attack
You need to scan using a full TCP connection. This method is more detectable but ensures a reliable result. What flag do you use?
Challenge 3.
The Forgotten UDP Ports
Your target may be hiding services on UDP ports. What flag lets you scan UDP ports instead of TCP?
Challenge 4.
Service Fingerprinting
You must identify running services on the open ports. What flag reveals service versions?
Challenge 5.
The OS Hunt
The Black Fox wants to know what operating system the target is using. What flag do you use?
Challenge 6.
Avoiding DNS Logs
You need to speed up your scan and avoid leaving DNS records. What flag disables DNS resolution?
Challenge 7.
Speed is Key
The client wants the scan done ASAP. What timing flag makes Nmap run at maximum speed?
Challenge 8.
The 1000 Gates
The Black Fox only wants the scan on the most common 1000 ports. What flag do you use?
Challenge 9.
Specific Target Ports
A secret server is listening on custom ports 8080 and 443. How do you tell Nmap to scan only these?
Challenge 10.
The Blacklist Bypass
To blend in with normal traffic, you must randomize your source IPs using decoys. What flag do you use?
Challenge 11.
Ghost Scan (Idle Scan)
You want to spoof your source IP by using an idle host. What flag do you use?
Challenge 12.
Parallel Scanning
You want to control how many hosts Nmap scans at once to optimize speed. What flag lets you set this?
Challenge 13.
Fragmentation Evasion
To bypass firewalls, you need to send fragmented packets. What flag do you use?
Challenge 14.
Delay the Scan
The target has an IDS that detects rapid scans. You must slow it down with a custom delay. What flag do you use?
Challenge 15.
IPv6 Infiltration
You find out the target runs on IPv6. What flag forces Nmap to scan IPv6 instead of IPv4?
Challenge 16.
The Firewall’s Worst Nightmare
You need to run a powerful scan that includes OS detection, version detection, script scanning, and traceroute. What flag does it all?
Challenge 17.
Script-Based Exploitation
You want to run Nmap’s built-in vulnerability detection scripts. What flag allows this?
Challenge 18.
Only TCP Ports, No UDP
The client requests a TCP-only scan, avoiding UDP entirely. What flag ensures only TCP is scanned?
Challenge 19.
Save Your Evidence
The Black Fox needs a formatted log of the scan. What flag saves the output in a grep-friendly format?
Challenge 20.
The Final Challenge: CIDR Attack
You must scan an entire subnet in CIDR notation (e.g., 192.168.1.0/24). What flag allows subnet scanning?
Mission Accomplished!
You have successfully completed "Operation Shadow Recon"!
Your scan results have revealed multiple vulnerabilities, and The Black Fox has rewarded you with a secret payload of encrypted files.
