Do you know the USB devices we carry each day can be converted into a bomb? You must be thinking like “yeah whatever.”
No, it’s true, a researcher just showed how a USB can be converted into a killer USB that can kill your whole PC within seconds.
Though, this is not the first time such a USB has been demonstrated. In March, the same researcher showed that a USB can cause harm to vital components of a system if plugged in. But, this time around the USB he demonstrated was significantly more powerful and was named as “Dark Purple”
The USB has been developed with a DC/DC converter, caps and FET. On plugging, the DC/DC converter charges the USB to -220V in the new version (in the old version it was -110V). This voltage is applied to the signal lines of the USB interface.
The process repeats itself until all the components of the PC are destroyed.
What’s more troubling about the version 2.0 is that the reaction rate is much more than the earlier version, which allows it to destroy the whole system within few seconds.
During the demonstration, the researcher lost his new laptop. This is what he said after the demonstration:
“Do not worry about the laptop, the new motherboard is on the way – and the laptop will live again,” He specifically bought new laptop (Lenovo Thinkpad X60) just for this experiment, according to the researcher’s blog post.
This is not the first time a USB has been used as a weapon. USB drives have been used many times for compromising systems in air-gapped networks.
Stuxnet worm is the best example in the recent past when a USB drive was used as a weapon. Stuxnet worm was designed to destroy centrifuges at a nuclear facility.
So, our advice for you would be to be very careful while using anyone’s USB (better still, do not use anyone’s USB in your system), as one wrong step on your side can put all your data on risk.

THE REAL DEAL R3 Data Recovery are Geniuses! I am almost speechless with what an incredible job you have done for me.
As a videographer my data is my life, You saved 1.2TB of footage and all of my projects from a 2TB portable hard drive that I dropped. As soon as it hit the floor I felt sick. I chose the emergency recovery which was worth every penny. A super competitive quote upfront that did not change through the recovery. I had a new drive back in 3 days with 100% recovery.
