contact2014年1月14日· A cold boot attack works in three stages: gain physical access to machine. power-cycle the machine to a special kernel. read and abuse memory. Despite what most people believe, DRAM doesn't lose its contents as soon as you turn it off. It holds memory for a couple of seconds even at room temperature.
contactWith this cold boot attack, if people lock their screens or even suspend their laptops, you could pull the power, grab the RAM contents and scrub it for any encryption keys. Essentially, you could compromise all of the common disk encryption techniques if you had a few minutes alone with a computer.
