A USB killer is a device that is designed to be portable and sends high-voltage power surges repeatedly into the data lines of the device it is connected to, which will damage hardware components on unprotected devices. Companies selling the device state it is designed to test components for protection from power surges and electrostatic discharge.
A USB Killer is a malicious device that resembles a standard USB thumb drive but is designed to physically damage or destroy the electronic components of the device it is plugged into. Here's how it generally works:
1. **Power Accumulation**: The USB Killer draws power from the host device's USB port and stores it in capacitors within the device.
2. **Discharge**: Once the capacitors are fully charged, the USB Killer discharges the stored power back into the host device's USB data lines.
3. **Damage**: This sudden surge of electricity can overwhelm the host device's electrical components, potentially causing irreversible damage to the motherboard, USB ports, and other critical components.
The primary intention of a USB Killer is to incapacitate or destroy the hardware, making it a significant security threat. It is used by malicious actors to sabotage computers, laptops, or other electronic devices with USB ports. It is important to be cautious and avoid plugging unknown or suspicious USB devices into your electronics.
