reverse-shell-techniques

An offensive-security playbook in the yaklang hack-skills collection, focused on establishing and stabilizing reverse shells during authorized penetration testing and red-team engagements. Per its description it surveys the common families of remote-shell techniques: language one-liners, encrypted channels via tools such as OpenSSL, socat, and ncat, web shells, upgrading a basic shell to a full interactive PTY, methods for transferring files to a target, PowerShell-based shells, and Windows payload generation. It is framed as an expert reference for operators who already have a foothold and need reliable, situation-appropriate command-and-control back to their machine. In a catalog context it is post-exploitation tooling used to demonstrate impact during an authorized assessment and to test whether egress filtering, EDR, and network monitoring detect outbound shell activity. Because reverse shells are a core offensive capability, the material should be used only within the scope of an engagement the tester is authorized to perform. Defenders can use awareness of these techniques to tune egress filtering, detect anomalous outbound connections and interactive PTY behavior, and harden systems against the shell-establishment and file-transfer methods described.
