A Security researcher has discovered a unique attack method that can be used to steal credentials from a locked computer ( but, logged-in ) and works on both Windows as well as Mac OS X systems. In his blog post published today, security expert Rob Fuller demonstrated and explained how to exploit a USB SoC-based device to turn it into a credential-sniffer that works even on a locked computer or laptop. Fuller modified the firmware code of USB dongle in such a way that when it is plugged into an Ethernet adapter, the plug-and-play USB device installs and acts itself as the network gateway, DNS server, and Web Proxy Auto-discovery Protocol (WPAD) server for the victim's machine. The attack is possible because most PCs automatically install Plug-and-Play USB devices, meaning "even if a system is locked out, the device [dongle] still gets installed," Fuller explains in his blog post . "Now, I believe there are restrictions on what types of devices are allowed to

Remember Killer USB ?? In March, a Russian security researcher devised a weird USB stick that is capable of destroying sensitive components of a computer when plugged-in. Now, the same researcher, nicknamed Dark Purple , has launched a new version of his computer-frying USB Killer pendrive – USB Killer version 2.0 . USB Killer 2.0 is much more powerful than the previous version and is able to "kill" more than just a PC it is plugged in. USB Killer 2.0 is More Powerful to Damage any Computer The first version of USB Killer was consist of a DC/DC converter, a few caps and an FET. When plugged into a system, the converter in the USB Killer would charge the caps up to -110V , apply that voltage to signal lines of the USB interface, and repeat the entire process until everything possible in the computer is broken down. However, the second version of USB Killer dump -220V directly onto the signal lines of the USB interface, which is powerful enough to
