how to get remote access to your hacking targets // reverse shells with netcat (Windows and Linux!!)

Netcat can be used to turn an outbound connection from a target into full remote command-line control, bypassing many firewall restrictions. The core idea is a reverse shell: instead of trying to connect into a protected machine (often blocked by inbound firewall rules), the target runs a command that connects back to an attacker-controlled listener. Once that connection lands, the attacker can interact with the target’s shell and issue commands like “whoami” and “ls,” effectively gaining remote access.

The walkthrough starts with the practical constraints. A home router typically blocks most inbound traffic, making direct remote access difficult. Reverse shells flip the direction: the target initiates the connection outward, which is usually allowed because it resembles normal, trusted traffic like browsing the web. Netcat—long used for networking tasks and sometimes called the “Swiss Army knife” of networking—becomes the mechanism for setting up the listener and triggering the callback.

For a Linux-to-Linux scenario, the attacker sets up a Netcat listener on a chosen port (kept under 1000 to reduce firewall detection risk). The listener uses flags for listening mode, no DNS lookups, verbose output, and a specific port, and on multi-interface systems it also binds to the correct source IP. On the target side, Netcat runs a command that connects back to the attacker’s IP and port and, where supported, spawns a shell (commonly “/bin/bash”). When the target connects, the attacker’s terminal receives an interactive session, demonstrating command execution and file listing.

The transcript then shifts to Windows, where the approach changes because traditional Netcat options vary by platform. Instead of relying on Netcat’s “-e” shell execution (often missing on many Linux builds and not consistently available on Windows), the Windows test uses PowerShell to download and run a reverse-shell payload. The attacker still runs the Netcat listener, while the Windows side launches PowerShell that fetches a .ps1 script from a GitHub repository and initiates the outbound connection back to the listener. The result is a reverse PowerShell session, giving interactive control over the Windows machine.

Finally, the same concept is demonstrated with a “Land Turtle” USB-powered Linux device running Netcat. The device can be plugged into a network switch or Ethernet port and powered via a USB power bank, then left hidden. Because Netcat on the device initiates the connection back to the attacker, the attacker can gain remote command execution and even run discovery tools like Nmap from the hidden foothold.

Throughout, the transcript emphasizes that reverse shells are a common technique behind real-world intrusions—often delivered via scripts or payloads through phishing or other compromise paths—and stresses defensive monitoring. Bitdefender is used as a sponsor example for blocking malicious files and scanning network traffic. The segment ends with a giveaway for two Land Turtles and a contest secret phrase: “network chuck turtle.”
