What is USB killer?

USB Killer is a modified USB drive that destroys computers when you insert it into the machine’s USB drive. There are different versions of this device, and you can even create a DIY version yourself for $3 or less.

USB Killer is often used as an example of why you should refrain from plugging in unknown USB devices into your systems. USB Killer drives are often disguised as air ionizers and fans, which can fool those with lax information security training.

How does USB killer inflict so much damage?

The power of USB Killer lies in its functional simplicity: the device is able to inflict so much damage on systems by taking advantage of the interplay between USB drives and power. USB Killer doesn’t use malware or special equipment. It just sends high-voltage power into the computer it is plugged into, effectively destroying the system. In fact, USB Killer has the potential to send up to 200 direct current volts into a USB port — a death blow for any machine.

But how does it work? USB Killer charges the capacitor bank by using an inverted DC-to-DC converter. This power is sent back into the computer via the USB interface and is repeated in a loop. We’ll talk about the physical portion of this in more detail a little later.

Who created USB killer and why?

The creation of USB Killer is mysterious, as there are a few origin stories floating around the internet. Some say that USB Killer was invented by a Hong Kong-based security team. Others say that a group of Russian hackers named “Dark Purple” invented it.

Regardless of the actual source, the reason for inventing USB Killer is more utilitarian and benevolent than you may think. In fact, it was made to test devices against the vulnerability that USB Killer exploits. This vulnerability has been an ongoing issue since USB technology supplanted other forms of storage media from the general market and is readily apparent from USB Killers’ ability to destroy most devices with USB ports.

USB Killer is sold commercially under the name USB Kill and can be foundhere. The product is marketed as a legitimate pentesting tool. It is worth noting that USB Killer comes with a sort of shadowy element, as you can purchase USB Killer without any apparent branding to reduce the suspicion of users. Depending on the intent and or negligence of the purchaser, this can lead to destructive results.
