PhoneInfoga
Information gathering framework for phone numbers
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. -

mkcert
Zero-config tool to make locally trusted development certificates
mkcert is a simple tool for making locally-trusted development certificates. It requires no configuration. Using certificates from real certificate authorities (CAs) for development can be dangerous or impossible (for hosts like example.test, localhost or 127.0.0.1), but self-signed certificates cause trust errors. Managing your own CA is the best solution, but usually involves arcane commands, specialized knowledge and manual steps. mkcert automatically creates and installs a local CA in the system root store, and generates locally-trusted certificates. mkcert does not automatically configure servers to use the certificates, though, that's up to you. The CA certificate and its key are stored in an application data folder in the user's home. You usually don't have to worry about it, as the installation is automated, but the location is printed by mkcert -CAROOT. -

kcp Kubernetes
Kubernetes-like control planes for form-factors
kcp can be a building block for SaaS service providers who need a massively multi-tenant platform to offer services to a large number of fully isolated tenants using Kubernetes-native APIs. The goal is to be useful to cloud providers as well as enterprise IT departments offering APIs within their company. kcp takes full advantage of Kubernetes API conventions, the glue that binds the cloud-native technology ecosystem together and imbues Kubernetes popular end-user experience, but kcp has unbound it from Kubernetes workload orchestration and clusters. kcp implements fully-isolated workspaces, each acting as its own Kubernetes-like cluster, with its own URL, its own set of APIs (e.g. different CRDs), its own RBAC, but as cheap and quick as a namespace. -

Gobuster
Directory/File, DNS and VHost busting tool written in Go
Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster. -

kubelogin
kubectl plugin for Kubernetes OpenID Connect authentication
Kubelogin is designed to run as a client-go credential plugin. When you run kubectl, kubelogin opens the browser and you can log in to the provider. Then kubelogin gets a token from the provider and kubectl accesses Kubernetes APIs with the token. If you install via GitHub releases, you need to put the kubelogin binary on your path under the name kubectl-oidc_login so that the kubectl plugin mechanism can find it when you invoke kubectl oidc-login. The other install methods do this for you. If the cached ID token is valid, kubelogin just returns it. If the cached ID token has expired, kubelogin will refresh the token using the refresh token. If the refresh token has expired, kubelogin will perform re-authentication (you will have to login via browser again). -
22
OWASP Amass

Ligolo-ng
An advanced, yet simple, tunneling/pivoting tool
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.
