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.

    The article doesn’t mention how it compensates for different keyboards. Like wouldn’t different switches and wear change the sound?

      Dude in the thumbnail is Samy. He’s been a bond villain for a long time now.

    So how do we fix this? Dumb nerds never think about the consequences of their creations.

      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.””

        Companies can’t even be convinced to have longer passwords on their wifi. And open office plans mean every computer faces a window

            But I work at companies and I would like my info to not be hacked. Their fuck ups affect employees and customers

            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.

    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…

        You’re not James Bond. Or a 1337 haxx0r. This technology isn’t even new. Why are you stanning this guy? It’s an assinine position to take.

    Oddly enough - all my keystrokes sound exactly the same which makes this person’s claim so much bullshit.
