Unleashing Security audits on the Go

The “Interrupt” is poised too revolutionize penetration testing, hardware analysis, and digital systems experimentation. This compact, handheld Linux device puts the power of a full-fledged security lab in the palm of your hand. It’s designed for security professionals, hardware hackers, and anyone interested in exploring the intricacies of digital security.

Core Components and Capabilities

At the heart of the Interrupt lies a Raspberry Pi Zero 2 W, boasting a quad-core ARM Cortex-A53 processor (1 GHz) and 512 MB of RAM. This provides a robust foundation for running Linux-based applications, including essential security tools. integrated WLAN (802.11ac) and Bluetooth 4.2 connectivity further enhance its versatility.

Beyond its core processing power, the Interrupt features:

• A vibrant 3.5-inch touchscreen (480×320 pixels) for intuitive interaction.
• A built-in keyboard for efficient command execution.
• A USB-C power supply coupled with a 2000 mAh lithium polymer battery for extended operation.
• A microSD card slot, allowing for expandable storage to accommodate large datasets and toolsets.
• Accessible GPIO pins, enabling connection to external hardware for in-depth system analysis.

sub-GHz Spectrum Analysis and Emulation

A standout feature of the Interrupt is its integrated CC1101 chip, which covers the sub-1 GHz frequency range (300 to 928 MHz). This capability allows users to analyze, save, and reproduce radio protocols commonly used in garage door openers, IoT devices, and other low-power communication systems. According to a recent report by Statista, the number of IoT connected devices worldwide is forecast to reach 29.4 billion units by 2030, highlighting the growing importance of securing these devices.

Furthermore, the Interrupt supports RFID reading and emulation, as well as the transmission and reception of IR signals, enabling control over a wide range of household appliances.

Open Architecture for Unfettered Customization

The Interrupt embraces an open architecture philosophy, empowering users to delve deep into the system. Users can install custom tools, modify scripts, and even work directly on the kernel. The hardware is designed for disassembly, allowing for the replacement of components such as the battery or display. This level of customizability makes the Interrupt an ideal platform for both learning and advanced security research.

Open architecture allows interventions in the system: users can install their own tools, adjust scripts or work directly on the kernel. The hardware can be disassembled and components such as battery or display can be exchanged.

Real-World application: Access control Auditing

Imagine a scenario where a security professional needs to assess the access control mechanisms of an office building. The Interrupt can be used to read, analyze, and emulate RFID tokens, effectively testing the security of the building’s entry points. Simultaneously, the device can monitor radio traffic from the access system, identifying potential vulnerabilities. All of these functions can be managed directly on the device, either through its graphical user interface (GUI) or via a full-fledged Linux terminal.

Kickstarter Success and Availability

The Kickstarter campaign for the Interrupt has already surpassed its funding goal, demonstrating strong interest in this innovative device. With hardware development complete and prototypes undergoing field testing, the Interrupt is slated for delivery in October/November 2025.

Early supporters can secure the basic package for a starting price of $169. This investment provides not only a versatile pentesting tool but also a fully modifiable, open-source device that promises to be a valuable asset for security enthusiasts and professionals alike.
