Memory attacks aren’t the only threat either. Alternatively, the RAM can be inserted into another motherboard, where the data can be fully retrieved. Once cooled, the system can be booted back up with a USB operating system to read and store the bit sequence from the RAM. This is done because temperature is proportional to the rate of charge decay or leakage in capacitors, so reducing the temperature of the RAM significantly increases the amount of time the data in it is retained, from a few seconds to minutes or even hours. In a cold boot attack, compressed air (or in some case, liquid nitrogen) is used to rapidly cool the laptop’s RAM as soon as it is powered off. This includes a cold boot attack, which takes advantage of the fact that RAM retains the memory stored in it for a few seconds after the laptop has been switched off. Keeping sensitive information like this in such an accessible place leaves the whole laptop vulnerable to breach.įor an attacker fortunate enough to discover a laptop in this state, there are a variety of techniques that can be successfully deployed to retrieve the DEK and other sensitive information directly from the memory. In the case of secure laptops running Full Drive Encryption (FDE), this suspended memory includes the DEK (Data Encryption Key) or with Self-Encrypting Drives (SED), the very credentials required to unlock the drive. As a result, when S3’s engaged, the laptop’s drive and other hardware power off, but its memory remains active, ready to spring back to life as soon as the user opens the lid back up or hits the power button. This is because sleep mode (S3) on most laptops is little more than a low power mode designed to save battery life. But what we don’t realise is that simply shutting the lid and putting the laptop into sleep mode can leave it much more vulnerable to cyber-attacks than we might think.

Hybrid Sleep places programs into the memory as well as on your disk, and only then it puts your computer into a flat-power state. As the name suggests, it is a mixture of Sleep and Hibernation. Hybrid Sleep is designed and used mainly for desktop users. Hibernation could be used when you know that you’re not going to use your laptop for an extended period and won’t have a chance to replenish the charge of the battery throughout that time. Among every power-saving state in Windows, Hibernation uses the slightest amount of power. All your open documents and programs are first put on your hard disk, and then Hibernation turns off your computer. The computer turns off whenever sleep function is triggered and resumes the work when required.ĪLSO READ: Top 10 Windows 10 Tips And Tricks You Wish You Knew Before Hibernation Sleep mode is triggered after a few minutes of inactivity or Closing the lid of a laptop or pressing the power button (needs to be configured).
