USBKill V4 Feature Overview

⚡ Powerful Hardware Update

The USBKill has evolved beyond a simple plug-and-zap device. The new V4 hardware framework enables advanced functionality and performance.

Aside from more powerful discharges and improved stability, the V4 has an internal, rechargeable battery, which allows for "Offline Attacks" - where the host device is not turned on.

"Offline Mode" also bypasses all known USB-C and Lightning (Apple/iPhone) security protocols, rendering the V4 the ultimate device for testing smartphones and modern hardware.

⏱️ Advanced Attack Modes

The USBKill has evolved, and so have the ways to use it. V4 Introduces single pulse and continuous pulse attack modes. By default, the V4 will not activate until triggered - giving pentesters and LEA ultimate discretion. The V4 can be triggered in multiple ways:

  • Remote Trigger: Trigger a single or continuous attack via dedicated remote control, up to 100m away from the device.
  • Smartphone Trigger: Control and trigger single or continuous attacks via the included Android and iOS smartphone app.
  • Timed Attack: Schedule a date and time when the USBKill will trigger. The V4 can stay dormant without power for over 200 days.
  • Magnetic Trigger: Trigger the USBKill with a magnet (stylish and covert magnetic ring included) by passing your hand over the device.
  • Classic Mode: Triggers the instant it is plugged into a USB drive.

Is the USBKill safe?

The USBKill has been designed and tested to be safe and efficient.
It is both CE Approved and FCC Approved, and built and tested with the utmost priority on user safety.

Although totally safe to operate, the USBKill is a high voltage device - and should be treated with appropriate precautions.

The USBKill V4 Pro and Basic share the same improved hardware: increased stability, internal battery for offline attacks.

The Pro Edition has several attack modes (Remote, Smartphone, Timed, Magnetic, Classic) and attack types (Single Pulse and Continuous Pulse). It can be configured via Smartphone, and triggered via dedicated remote control. The Pro can also be configured in "Classic Mode" - discharge is triggered when the device is plugged in ("Plug and Zap")

The Basic Version has no wireless functionality, and no extended attack modes. It is triggered manually via the included Magnetic Ring.

If performance is important: consider the Pro Edition. If budget is important, the Basic Edition. If you need the original behaviour, the V4 Classic.

Technical Questions

What is an "online" and "offline" attack?
The original V3 USBKill device rapidly charges its capacitors from the USB power lines when plugged into a powered (online) USB port. When the device is charged, -200VDC is discharged over the data lines of the host device. This cycle happens many times per second.

The USBKill V4 has an internal battery (recharged via USB), meaning it does not require power from a host device even if the device is turned off - and "offline".

How many times can the device be used?
Unlimited times.

What is the battery life?
The battery can make over 1000 discharges on a single charge, and has over 200 days in standby mode - with wireless enabled
