For those in the dark, Microsoft Windows XP, 7, 8 and 10 login password can be cracked via Brute Force method, what is Brute Force ? The brute-force attack is still one of the most popular password ‘guessing’ methods. Basically it works by guessing every single combination of number, words and character found on the keyboard.
Not only can USB devices contain malware and spread infection as soon as they are connected to a network, they can also be booby-trapped and take over keyboards all while running in the background without the user ever realizing that their computer has been hijacked. For instance, a booby-trapped USB drive was the origin of the infamous Stuxnet worm that infected Iranian nuclear facilities, and has since been billed as the most sophisticated usb lock computer virus ever created. Earlier this year, a researcher created a USB stick dubbed USB Killer that is capable of delivering a 220-volt charge to the attached computer within seconds of being connected. The USB stick looks like a normal USB drive and there are no other signs that it is malicious. Microsoft also recently revealed a Windows vulnerability that could allow an attacker to execute malicious code from a booby-trapped USB.
The downside is that it is one more thing to carry around and keep track off, it requires the Chrome browser to work, and that it requires a USB port to work which makes it useless for a lot of protect usb mobile devices,” security researcher Andreas Lindh told the Guardian over email. The researchers are due to present their research at the Black Hat security conference in Las Vegas next week.
