    Tor Browser

    Tor Browser

    Browser for using Tor on Windows, Mac OS X or Linux

    Tor Browser enables you to use Tor on Windows, Mac OS X, or Linux without needing to install any software. Tor is a software that bounces your communications around a distributed network of relays run by volunteers. This effectively prevents anyone watching your Internet connection from learning what sites you visit; it prevents the sites you visit from learning your physical location; and allows you access to sites which are blocked. Tor Browser can run off a USB flash drive, comes with...

    Algo VPN

    Algo VPN

    Set of Ansible scripts that simplifies the setup of a personal VPN

    ...If an attacker can compromise a VPN provider, they can monitor a whole lot of sensitive data. Paid-for VPNs tend to be insecure: they share keys, their weak cryptography gives a false sense of security, and they require you to trust their operators. Even if you’re not doing anything wrong, you could be sharing the same endpoint with someone who is. In that case, your network traffic will be analyzed when law enforcement makes that seizure.

    BeEF

    BeEF

    The browser exploitation framework project

    ...It is a penetration testing tool that focuses on the web browser. Amid growing concerns about web-borne attacks against clients, including mobile clients, BeEF allows the professional penetration tester to assess the actual security posture of a target environment by using client-side attack vectors. Unlike other security frameworks, BeEF looks past the hardened network perimeter and client system, and examines exploitability within the context of the one open door: the web browser. BeEF will hook one or more web browsers and use them as beachheads for launching directed command modules and further attacks against the system from within the browser context.

    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...

Fortunately, thanks to the new features introduced in HTTP/2, it's now possible to create true REST APIs fixing these problems with ease.
