kscan is a network security scanner and service fingerprinter used to discover active hosts and open ports. It functions as a network protocol analyzer and internal network mapper to identify reachable gateways and analyze the network surface area of target environments. The tool integrates external asset discovery by retrieving target hosts through external intelligence services and verifying their availability. It also operates as a credential brute force tool, testing authentication strength across multiple protocols using automated username and password dictionaries. The project covers n
This project is a network reconnaissance framework and internet metadata database used for collecting, storing, and analyzing data from active scanners and passive traffic captures. It functions as a threat intelligence aggregator and passive traffic analysis tool, merging scan results from multiple tools into a unified dataset for security investigation. The system distinguishes itself through its ability to visualize network assets using heatmaps and geographic charts to correlate autonomous systems and domain names. It provides external attack surface management by aggregating metadata to
Tsunami Security Scanner is a network vulnerability scanner and security auditor designed to identify high-severity flaws across network assets. It functions as an asynchronous security probe engine that utilizes automated probes and specialized detection logic to find critical weaknesses and prioritize remediation efforts. The project is distinguished by a plugin-based scanning engine, which uses a modular architecture of interchangeable detection plugins to identify vulnerabilities. This extensibility allows for the development and integration of custom security plugins to expand the variet
reconftw is an attack surface management framework and reconnaissance workflow orchestrator designed to automate the discovery, mapping, and monitoring of external digital assets. It operates as a modular tool-chain pipeline that coordinates a sequence of security tools to perform intelligence gathering and vulnerability scanning. The project distinguishes itself through a cloud-native deployment model that parallelizes scanning workloads across a fleet of remote VPS instances to bypass local resource constraints. It utilizes container-based environment isolation to ensure consistent executio
