OFFENSIVE SECURITY - PENETRATION TESTING - RED TEAMING - ETHICAL HACKING
The ultimate automated scanner for penetration testers and red teamers
Sn1per is an automated reconnaissance scanner that collects data about websites, IP addresses, networks, ports, services, vulnerabilities, operating systems, and more. It combines various security tools into a single, powerful framework.
Performs automated reconnaissance on web services, applications, and network infrastructure
Executes multiple scanning tasks simultaneously for improved efficiency
Generates detailed HTML reports with findings and vulnerability assessments
Incorporates over 100 security tools into a unified scanning platform
Sn1per offers multiple scanning modes to adapt to various penetration testing scenarios:
Standard scan using default settings
Non-intrusive scan to avoid detection
Focuses on web application vulnerabilities
Open source intelligence gathering
Basic reconnaissance only
Scans all 65535 ports
Here's how to get started with Sn1per for penetration testing:
Windows Print Spooler Remote Code Execution Vulnerability
Multiple known vulnerabilities in outdated WordPress installation
Server supports deprecated TLS 1.0 protocol
Web server directory listing exposes sensitive file structure
Sn1per's scans generate distinctive network patterns that can be analysed with Wireshark
Typical port scan traffic pattern from Sn1per reconnaissance
HTTP/HTTPS traffic patterns during web vulnerability assessment
Filter to detect Sn1per web application scanning activity
Filter to detect typical Sn1per SYN scan patterns

Sn1per is a sophisticated reconnaissance toolkit built in Bash that orchestrates multiple open-source security tools to provide a comprehensive security assessment.
At its core, Sn1per functions as a modular orchestration engine that sequentially invokes specialized security tools based on the scanning mode and discovered attack surface. The workflow generally follows this pattern:
1. Target Identification
├── DNS Resolution
├── WHOIS Lookup
└── IP Range Determination
2. Network Enumeration
├── Port Scanning (via Nmap, Masscan)
├── Service Detection
└── Operating System Identification
3. Service Enumeration
├── Web Server Fingerprinting
├── CMS Detection
└── API Discovery
4. Vulnerability Assessment
├── Known CVE Checking
├── Misconfigurations
└── Default Credentials
5. Reporting
└── HTML Report GenerationSn1per leverages Nmap's SYN/ACK scanning methodology with custom timing templates optimized for various scanning scenarios. In stealth mode, it implements delayed TCP scanning with randomized packet timing to evade intrusion detection systems.
Written in Bash, Sn1per uses GNU Parallel and background processing to execute multiple tools concurrently, significantly reducing scan times while managing system resource allocation efficiently.
For HTTP/HTTPS services, Sn1per employs a layered approach: initial fingerprinting with Whatweb, followed by vulnerability scanning with Nikto, and targeted CMS scanning with specialized tools like WPScan for WordPress.
All scan data is parsed, normalized, and compiled into a structured HTML report using a combination of awk, sed, and grep for text processing, with severity-based vulnerability classification according to CVSS scoring.
Sn1per implements several technical optimisations to balance thoroughness with speed:
Understanding the internal architecture of Sn1per reveals how it efficiently coordinates multiple security tools into a cohesive scanning platform.

↓Data Analysis & Visualisation
Sn1per implements a pipeline architecture where data flows through several processing stages:
At each stage, scan results are persisted to disk to prevent data loss in case of system failure. The modular design allows for easy extension with custom scanning modules and integration with additional security tools.
