Attack Surface Management | Criminal IP ASMCriminal IP’s Attack Surface Management (ASM) is a threat-intelligence–driven platform that continuously discovers, inventories, and monitors every internet-connected asset associated with an organization, including shadow and forgotten resources, so teams see their true external footprint from an attacker’s perspective. The solution combines automated asset discovery with OSINT techniques, AI enrichment and advanced threat intelligence to surface exposed hosts, domains, cloud services, IoT endpoints and other Internet-facing vectors, capture evidence (screenshots and metadata), and correlate findings to known exploitability and attacker tradecraft. ASM prioritizes exposures by business context and risk, highlights vulnerable components and misconfigurations, and provides real-time alerts and dashboards to speed investigation and remediation.

Portable OpenSSH
Complete implementation of the SSH protocol
Portable OpenSSH is a cross-platform implementation of the Secure Shell (SSH) protocol that provides encrypted communication and secure remote access over untrusted networks. It originates from the OpenSSH project maintained by the OpenBSD community and adapts the core OpenBSD implementation so it can run on many operating systems including Linux, macOS, and Windows. The software suite enables administrators and developers to securely log into remote systems, transfer files, and create encrypted tunnels for network traffic. By encrypting all communications between client and server, it protects against threats such as eavesdropping, connection hijacking, and data interception. The portable distribution follows the development of the main OpenSSH codebase while adding compatibility layers for multiple operating systems and authentication systems. -

ssh-chat
Chat over SSH
ssh-chat is a custom SSH server written in Go that allows you to chat over SSH connection. When you open your terminal and type in a command, instead of getting a shell you get a chat prompt. With ssh-chat you get a simple chat room over a secure shell connection, where you can send and receive private messages, check any user's public key fingerprint for identification purposes, and more. You can change the color theme of the chat, block or kick users, and chat on just about any platform where an SSH client is available, including on mobile. -

Russh
Rust SSH client & server library
Russh provides a Rust library for implementing SSH clients and servers with a modern, async-friendly design. It exposes building blocks for authentication, channel management, port forwarding, and key handling, allowing you to embed SSH functionality directly into Rust applications. The API is designed to be explicit and composable, making it possible to implement custom behaviors like reverse tunnels, interactive shells, and service multiplexing. Because performance and safety are central, the code leverages Rust’s type system to reduce classes of runtime errors common in network protocol implementations. The project also includes examples and discussion threads that show how other tools integrate it for web-based clients or gateway services. For teams building terminals, proxies, or embedded management planes, it offers a robust foundation without shelling out to external binaries. -

HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

http-proxy-tunnel
Create nested tunnels through HTTP proxies
Http-proxy-tunnel creates TCP tunnels through http proxies that permit the CONNECT method. It differs from other proxy tunnelling programs in that it can tunnel through multiple proxies, and can use SSL tunnels. These abilities mean that in combination with a web server that can proxy (such as Apache) you can serve normal web pages from ports 80 and 443 and connect to the server (using ssh say) via those ports at the same time. All available documentation can be read online at http://http-proxy-tunnel.sourceforge.net/ -
