Forensic software can exploit a seven-year-old FireWire design error to snoop system memory for passwords, even for devices that are locked or in sleep mode.
Updated forensic software can steal Apple OS X login passwords in minutes, even when the devices are locked or asleep.
To be successful, however, users of the software, Passware Kit Forensic v11, must have physical access to the target Mac device, as well as a FireWire cable connection. At that point, the software can capture the password data from the Mac’s memory, even on the latest version of Apple’s operating system, Mac OS X Lion.
