S3Scanner is a security tool for auditing public access and misconfigured permissions across S3-compatible storage providers. It functions as a storage auditor and security scanner designed to identify open buckets, enumerate publicly accessible objects, and exfiltrate data from misconfigured cloud environments. The project is distinguished by its integration with message brokers, allowing it to consume target lists for large-scale cloud infrastructure audits. It also provides utilities for dumping the entire contents of misconfigured buckets to local directories and calculating the total siz

recon-ng is an open source intelligence reconnaissance framework designed to automate the collection and aggregation of public information. It is a modular intelligence tool that utilizes a system of pluggable modules to harvest target data, resolve DNS queries, and parse web content. The framework is built as an API-driven tool with a programmatic interface to integrate with other security workflows. It is provided as a containerized application, using Docker to ensure a consistent environment for running reconnaissance tasks and managing a persistent data store. Its capabilities cover exte

RustScan is a high-speed TCP network scanner written in Rust, designed for security reconnaissance and network mapping. It functions as an automated port discovery engine that identifies open ports on remote hosts using IPv6 addresses, CIDR ranges, or bulk input files. The tool is built for rapid surface area discovery, utilizing parallel port processing and OS-aware performance optimizations to identify active services. It allows for scan precision tuning through adjustable connection timeout thresholds and concurrent request controls to balance speed and accuracy. The system integrates wit

AttackSurfaceMapper (ASM) is a reconnaissance tool that uses a mixture of open source intelligence and active techniques to expand the attack surface of your target. You feed in a mixture of one or more domains, subdomains and IP addresses and it uses numerous techniques to find more targets. It…

Amass is a network attack surface mapper and reconnaissance framework designed to discover and map the external, internet-facing infrastructure of a target organization. It functions as an open source intelligence tool that identifies public network boundaries and locates hidden or forgotten subdomains to define an organization's total reachable footprint. The project utilizes passive-source data aggregation from external APIs and public databases alongside active DNS brute-forcing and recursive subdomain expansion. It employs a graph-based asset mapping system to visualize the relationships

Sn1per is a vulnerability management platform and penetration testing orchestrator designed to automate reconnaissance, vulnerability scanning, and exploit verification. It functions as a dockerized security toolkit that coordinates multiple tools into a unified automated pipeline to identify security flaws across network and web assets. The platform features an attack surface manager for discovering internet-facing assets through OSINT, DNS enumeration, and certificate transparency. It distinguishes itself with an AI-powered security analyzer that uses large language models to summarize scan

Sublist3r is a subdomain enumeration tool and passive reconnaissance framework designed to discover subdomains by querying search engines and public intelligence sources. It functions as a security tool for identifying the digital footprint of a target domain. The project provides both passive enumeration through multi-source API aggregation and active discovery via a DNS brute force tool. It includes a TCP port scanner to identify active services and open ports on discovered subdomains, facilitating attack surface mapping. The tool can be used as a standalone utility or as a Python security
