Aug 20, 2018 A potential answer is to use a data-blocking device, also known as USB condom. An electronic accessory like this blocks the data pins on a USB cable and allows only power to go through.
- Nov 22, 2016 There is now a small device that can be used for hacking into screen-locked Mac computers and computers from other brands, and it just costs $5 to make. The device is called PoisonTap and it is.
- Sep 09, 2016 The time it takes for a USB device to capture credentials from a system using this attack is around 13 seconds. He used two ethernet dongles USB Armory and Hak5 Turtle. Fuller successfully tested his attack against Windows 98 SE, Windows 2000 SP4, Windows XP SP3, Windows 7 SP1, Windows 10 (Enterprise and Home), OS X El Capitan, and OS X Mavericks.
- The device works by only allowing a connected USB cable or device to exchange power — not data — with your computer. 'There are tools out there that can alert you when a new USB device is.
- Aug 21, 2017 Supporting the USB 2.0 standard, this hacking device works with WEP, WPA, WPA2, TKIP and even AES encryption. It has a wide compatibility for operating systems it works with as well. The hacking device can run on Linux, Windows versions from 2000 up until 8 and MacOS 10.5 and 10.5.
Most users lock their computer screens when they temporarily step away from them. While this seems like a good security measure, it isn’t good enough, a security researcher demonstrated this week.
Security researcher Rob Fuller has discovered a unique attack method that can steal PC credentials from Windows and Mac computers.Fuller’s attack is effective against locked computers on which the user has already logged in.

Fuller used USB-based Ethernet adapters, for which he modified the firmware code to run special software that sets the plug-and-play USB device as the network gateway, DNS, and WPAD(Web Proxy Auto-discovery Protocol ) servers on the computer it’s connected to.
The attack is possible because most computers will automatically install any plug-and-play USB device.
USB is Plug-and-Play. This means that even if a system is locked out, the device still gets installed,” Fuller wrote on his blog .
“Now, I believe there are restrictions on what types of devices are allowed to install at a locked out state on newer operating systems (Win10/El Capitan), but Ethernet/LAN is definitely on the white list.”
Mdified device includes software that intercepts these credentials and saves them to an SQLite database. The password is in its hashed state, but this can be cracked using currently available technology
According to Fuller, computers in a locked state still generate network traffic, allowing for the account name and hashed password to be extracted. The time it takes for a USB device to capture credentials from a system using this attack is around 13 seconds. He used two ethernet dongles USB Armory and Hak5 Turtle.
Fuller successfully tested his attack against Windows 98 SE, Windows 2000 SP4, Windows XP SP3, Windows 7 SP1, Windows 10 (Enterprise and Home), OS X El Capitan, and OS X Mavericks.
He says the attack was successful against Windows 98 SE, Windows 2000 SP4, Windows XP SP3, Windows 7 SP1, Windows 10 (Enterprise and Home), OS X El Capitan, and OS X Mavericks. He is about to test linux OS.
You can use a Universal Serial Bus(USB) to connect printers, scanners, digital cameras, webcams, iPods, joysticks, speakers, keychain disk drives, piano keyboards, and even your mouse and computer keyboard to your Mac.
Plugging in a USB device is as simple as plugging it in (though sometimes you have to load software first). You can often remove USB devices from the computer without causing harm by merely pulling the cable out of the jack.
Sometimes, however, you need to let your Mac know before you pull out the cable. To remove an iPod connected by USB, for example, your Mac wants you to click a tiny little icon in the iTunes software source list, next to the name you’ve assigned the portable music player. Failure to click the icon can cause unpleasant consequences.

If you plug a USB device into a port in the keyboard and it doesn’t work, try plugging it into a USB port directly on the back or side of the computer.
USB generally works great. But given all the devices that use USB, you may run out of available ports. In that case, you can buy a USB expansion hub — preferably one that you can plug in to an electrical outlet.
The state of the art for USB ports is USB 2.0. Older Macs have slower USB 1.1 ports.
