The Pocket Guide to the Packet Squirrel: Tips and Tricks

As cybersecurity and ethical hacking continue to rise in importance, an understanding of such tools as the Packet Squirrel becomes pivotal. The Packet Squirrel, a product of Hak5 company, is an innovative pocket-sized device that offers sophisticated traffic manipulation and data capture functionalities. Aimed at IT security enthusiasts, cybersecurity professionals and ethical hackers, the Packet Squirrel serves as a robust tool for performing routine security checks, analysis and auditing. Whether you're new to this device or a savvy Packet Squirrel user, this guide presents essential tips and tricks to make the most out of this small but powerful device.

Understanding The Basics

Before we dive into the intricacies, it is vital to understand what Packet Squirrel is. It's a tiny Ethernet multi-tool designed for network security, enabling users to conduct operations such as TCP Dump, DNS spoofing, and VPN tunneling. The device is usually plugged between two Ethernet cables and offers capabilities to both capture and manipulate packets without detection. Despite its small size, Packet Squirrel is praised in the industry for its capabilities and covert nature.

Becoming Familiar With The Interfaces

The Packet Squirrel device comes with four positions. The first position (closer to the Ethernet plug) is the arming mode or programming mode. The second and third positions are for user script mode, and the final position is to disable the device. In the arming mode, one can update the firmware. The device acts as Mass Storage Device when connected to a computer, allowing for easy transfer of scripts and payloads.

Utilizing Packet Squirrel Effectively

The true power of Packet Squirrel comes from its adeptness at network penetration, attack, and audit. Ethics come into play here - use it for good to uncover and patch loopholes in your systems, rather than for malicious intent. Here are some recommendations:

1. Exploit The Power Of TCP Dump

Packet Squirrel comes preconfigured with TCP Dump capabilities, allowing users to capture and analyze network traffic. One of the useful tricks is to connect a USB drive in the arming mode, label payload 1 or 2 as 'tcpdump', and start sniffing traffic. It allows you to understand network functions, and spot potential security concerns.

2. Deploy Cloud C2 feature

This feature provides the ability to control your Packet Squirrel (and other Hak5 gear) over the cloud. Once set, it will enable you to direct operations from a remote location easily and effectively.

3. VPN Your Connection

The device's OpenVPN capabilities offer easy access to private network resources from all around the globe, making it a useful tool for remote network security operations.


The real hackery of the Packet Squirrel comes from the community of hackers writing scripts optimal for conducting the ultimate cyber operations. They create scripts for all sorts of tasks but always be extra cautious - a script from an unreliable source may cause unknown damages. It's good practice to understand and scrutinize a script from the community before blindly using it.

In conclusion, the Packet Squirrel is an powerful and covert Ethernet multi-tool that lets you conduct cybersecurity operations with finesse. Its capabilities in TCP Dump, penetration testing and VPN tunneling, together with its compact and portable design, make it a valuable tool in the cybersecurity industry. A good understanding of this guide will certainly help you to wrestle with various network-sized challenges.
