Open Source Go Security Software for ChromeOS

PhoneInfoga is an open-source intelligence framework focused on gathering and analyzing information related to international phone numbers. The tool aggregates data from multiple scanners and external services to provide contextual intelligence such as country, carrier, line type, and potential VoIP provider details. It is designed primarily for investigators, analysts, and security researchers who need structured phone-number reconnaissance rather than real-time tracking. PhoneInfoga intentionally avoids automation of invasive actions and instead assists manual investigations by correlating publicly available data. The platform includes both a command-line interface and a web client backed by a REST API, making it suitable for integration into larger investigative workflows. Because it relies heavily on external data sources, its effectiveness depends on proper configuration of scanners and APIs.

A post-exploitation framework for Linux/Windows. Initially, emp3r0r was developed as one of my weaponizing experiments. It was a learning process for me trying to implement common Linux adversary techniques and some of my original ideas. So, what makes emp3r0r different? First of all, it is the first C2 framework that targets Linux platform including the capability of using any other tools through it. Take a look at the features for more valid reasons to use it.

Ligolo-ng is a simple, lightweight and fast tool that allows pentesters to establish tunnels from a reverse TCP/TLS connection using a tun interface (without the need of SOCKS). When running the relay/proxy server, a tun interface is used, packets sent to this interface are translated and then transmitted to the agent's remote network. You need to download the Wintun driver (used by WireGuard) and place the wintun.dll in the same folder as Ligolo. You can listen to ports on the agent and redirect connections to your control/proxy server. You can easily hit more than 100 Mbits/sec. Here is a test using iperf from a 200Mbits/s server to a 200Mbits/s connection.

Subfinder is a high-performance passive subdomain discovery tool built for fast and reliable asset enumeration. It focuses exclusively on collecting valid subdomains from a wide range of passive online sources, prioritizing accuracy and speed over intrusive scanning techniques. The project is widely used in bug bounty hunting, penetration testing, and attack surface mapping because it minimizes noise while producing actionable results. Its modular architecture allows users to enable dozens of data providers through API keys, expanding coverage as needed. Subfinder integrates easily into automation pipelines and CI workflows thanks to its clean command-line design and structured output formats. The tool is intentionally specialized, doing one job extremely well rather than attempting to be an all-in-one scanner. In practice, Subfinder serves as a foundational building block for modern reconnaissance stacks.

age is a security-oriented tool and library by Filo Sottile. age is a simple, modern, secure encryption utility (and Go library) that emphasizes minimal configuration and strong defaults. It provides small explicit keys, no complex options, and is designed for UNIX-style composability; you can pipe into it, integrate it into scripts, etc. It supports a clearly defined format and promotes interoperability across implementations (there are Rust, TypeScript, etc). The project is well-suited for personal data encryption, backup use-cases, scripting encryption workflows, and embedding encryption in tools. Because of its design philosophy, it avoids the bloat of many older encryption utilities while maintaining strong cryptographic hygiene. It’s especially useful for developers or system administrators who want to adopt encryption without learning a multitude of options.

Litestream is a standalone disaster recovery tool for SQLite databases. It runs as a background process and continuously replicates SQLite changes to another file or remote storage such as S3. The project is designed to make SQLite more practical for production apps that need simple recovery without operating a full database server. It communicates through the SQLite API, which helps reduce the risk of corrupting the database. Litestream is written mainly in Go and includes CLI tooling, Docker support, tests, documentation, and storage-related packages. It is useful for small services, embedded applications, and self-hosted systems that want lightweight replication and point-in-time recovery behavior.

Uncover is an open source reconnaissance tool designed to quickly discover exposed hosts on the internet by querying multiple search engine APIs through a unified interface. It acts as a Go-based wrapper around well-known internet intelligence platforms, allowing users to gather information about publicly accessible systems from a single command-line tool. By integrating with services such as Shodan, Censys, FOFA, ZoomEye, and others, the tool enables security professionals to efficiently search for internet-facing assets and services. The tool is built with automation in mind, making it suitable for security workflows and pipelines used by penetration testers, researchers, and bug bounty hunters. Instead of manually querying several search engines separately, uncover aggregates results from supported providers and returns them in a standardized format. This approach simplifies large-scale reconnaissance tasks and speeds up the discovery of exposed infrastructure or services.

GoSearch is an open source OSINT tool designed to investigate a person's digital footprint by searching for usernames across hundreds of websites. The tool scans more than 300 platforms to determine whether a specific username exists on social networks and other online services. Built with the Go programming language, it aims to provide faster performance compared to similar tools written in other languages. GoSearch was inspired by the well-known Sherlock username search tool, but it attempts to address several of its limitations such as slow execution, outdated sources, and inaccurate results. The tool reduces false positives and false negatives by clearly marking uncertain matches, allowing users to quickly identify reliable results. In addition to username searches, GoSearch can check various breach intelligence databases for compromised credentials linked to a username. If password hashes are found in breach data, the tool can attempt to crack them using the Weakpass database.

Gitrob is an open source reconnaissance tool designed to identify potentially sensitive files that have been committed to public GitHub repositories. It helps security professionals, researchers, and organizations detect accidental data exposure by scanning repositories associated with specific GitHub users or organizations. The tool works by cloning repositories and analyzing their commit history to search for files that match predefined signatures of sensitive data. These signatures are used to flag items such as credentials, private keys, configuration files, and other materials that may expose confidential information. By automatically inspecting repository histories, Gitrob simplifies the process of identifying security risks that might otherwise remain unnoticed in publicly accessible codebases. The results of the scan are presented through a built-in web interface that allows users to browse findings, review flagged files, and analyze potential leaks more efficiently.

asnmap is a command line tool and Go library designed to quickly map network ranges belonging to organizations using Autonomous System Number (ASN) data. It allows users to convert different types of inputs (such as ASN numbers, IP addresses, domain names, or organization names) into their associated CIDR ranges. This capability makes it particularly useful for security researchers, penetration testers, and reconnaissance workflows that require identifying network infrastructure owned by a target organization. asnmap retrieves ASN-related data and returns structured results that can be easily integrated into automated pipelines. Output can be generated in multiple formats including plain text, JSON, and CSV, enabling flexible data processing and analysis. asnmap also supports reading input from standard input and piping its results directly into other command line tools for chained workflows.

Berglas is a command-line tool and Go library for managing secrets on Google Cloud in a way that reduces the manual work typically involved in secret handling. It is built to store and retrieve secrets securely by encrypting them with Cloud KMS and storing them in Cloud Storage, while also providing an interoperable layer for Secret Manager. The project serves two related purposes: as a CLI, it automates secret encryption, decryption, and storage workflows, and as a library, it helps inject secrets into supported Google Cloud runtimes. This makes it useful for teams that want a more programmable and cloud-native approach to secret distribution without hardcoding sensitive values into applications or deployment pipelines. Because it is written in Go and distributed in multiple ways, including binaries, Docker, Homebrew, and source installation, it fits a variety of developer environments and operational setups.
