Watch How a Hacker’s Infrared Laser Can Spy on Your Laptop’s Keystrokes
www.wired.com

Hacker Samy Kamkar is debuting his own open source version of a laser microphone—a spy tool that can invisibly pick up the sounds inside your home through a window, and even the text you’re typing.

          Since that function is usually meant for night vision, I wonder how well a security camera can pick out the laser during the day i.e. when the IR sensors are being swamped by daylight also coming in through the window

          actually thats UV. transition lenses won’t change with a glass window thats not open. infrared is basically heat and does indeed pass through. Cars in the sun would not get hot so fast if they did not let in infrared.

              if this yahoo from the internet I found in a search is right then its both:

              “Glass will bock low frequency IR (red hot), but allow the passage of high frequency (white hot) IR. Hence, the heat of the sun will easily pass into a greenhouse, but once this energy is converted into low frequency heat by the objects within that absorb it, then the resulting low frequency heat is trapped. Hence, the Greenhouse Effect.”

    Great, now hackers and spies can detect my typing instead of using RATs or Trojans or packet sniffers, or just beating me with a $5 wrench (XKCD)

    Also:

    The trick, which takes advantage of the subtle acoustics created by tapping different keys on a computer, works even without a view of the computer’s keyboard, so long as the hacker has a line-of-sight view of any relatively reflective portion of the target laptop.

    So… Closing the curtains is all it takes to defeat this amazing technological method. GG.

      I’m not sure why you’re so dismissive of this? It’s kind of asinine.

      Does everyone everywhere only ever use computers in an enclosed room? Is everyone with something value to exfiltrate easily accessible to kidnap and beat with a wrench?

      This is valuable for corporate espionage, political purposes, or for nation states. If miniaturized, even easier for targeted attacks where it might be difficult to inject malware, or for broad attacks on office workers.

      And the best part is that it doesn’t leave a trace which beating someone with a wrench and malware would do…

      From the article: “Even knowing that Kamkar’s silent, invisible, long-distance laser spy trick exists, how does anyone hide their secrets from it? He suggests that companies install double-paned or reflective glass. Some security device companies also sell protection devices that affix to windows and vibrate them to prevent laser microphone spying, and Kamkar concedes he hasn’t tested his attack against those. But he also suggests a safer countermeasure: “Don’t work on computers visible from a window,” he says. “Or just have dirty windows.””

            The problem is the companies aren’t suffering the majority of the consequences of the security breaches, it’s the people these companies have personal information on & that includes people who have never done business with these companies but that these companies purchased data on.
