No one ever thought earlier to use computer power against the most intelligent machine on earth after Humans Brain.
A Hong Kong-based technology manufacturer is selling a USB thumb drive called USB Kill 2.0 that can fry any unauthorized computer it’s plugged into by introducing a power surge via the USB port. It costs$49.95.
How does USB Kill 2.0 work?
As the company explains, when plugged in, the USB Kill 2.0 stick rapidly charges its capacitors via the USB power supply, and then discharges – all in a matter of seconds.
The USB stick discharges 200 volts DC power over the data lines of the host machine and this charge-and-discharge cycle is repeated several numbers of times in just one second, until the USB Kill stick is removed.
“When tested on computers, the device isn’t designed or intended to erase data,” the company says. “However, depending on the hardware configuration (SSD [solid-state drive] vs. platter HDD [hard disk drive]), the drive controllers may be damaged to the point that data retrieval is impractical.”
“Any public facing USB port should be considered an attack vector,” the company says in a news release. “In data security, these ports are often locked down to prevent exfiltration of data or infiltration of malware, but are very often unprotected against electrical attack.”
When And For Whom USB KILL Would Be Useful?
USB Kill stick could be a boon for whistleblowers, journalists, activists, and, not to forget, cyber criminals, who want to keep their sensitive data away from law enforcement as well as cyber thieves.
It is like, if you’re caught, kill yourself. In the same fashion as terrorists do. Here I mean to kill the data from your laptop if the law enforcement has caught your laptop. And USB Kill stick does the same for you.However, the company claims to have developed USB Kill 2.0 stick for the sole purpose of allowing companies to test their devices against USB Power Surge attacks and to prevent data theft via “Juice Jacking” attacks.
