Mouse for hacker, for gamer and DIY-maniac



    While marketers write for marketers about 16 million colors of mouse illumination, gamers for gamers make devices with unrealistic sensitivity, I decided to delve into the insides of the super-duper modern mouse Roccat TYON with my green cat ( anboxing and testing are available on GeekTimes ).

    If you believe the description, then inside it settled 32-bit processor (72MHz Turbo Core V2 32-bit Arm based MCU) and half a megabyte of memory. Not only is this mouse smarter than my first computer for programming and it is more expensive than my first netbook, so the system of achievements is also built into the mouse itself.
    Performance characteristics are impressive
    (I don’t know if they are justified, whether they can come in handy, but still cool)
    • Laser sensor Pro-Aim R3 up to 8200dpi
    • 1000Hz polling rate
    • 1ms response time
    • 12000 frames / s, 10.8 megapixels
    • Acceleration 30g
    • 3.8 m / s (150 inch / s)
    • 16-bit data channel
    • Launch Distance 1-5mm
    • Built-in tracking and distance control module
    • 32-bit MCU Arm 72MHz Turbo Core V2 microprocessor
    • 576KB of memory on board
    • Hand micro-shake smoothing function
    • 1.8m Braided USB Cable


    In short, I cried and ate a cactus sawing a mouse for 7.000 rubles (thanks to the official representatives in Roccat in Russia). And along the way, I gathered up some useful information that I wanted to share.

    About inspiration for the DIY community, about what threats for users opportunities for hackers lurk in mice - under the cut

    Mouse through the eyes of a hacker


    2011



    Pentragers from Netragard. Their note on this. They glued the teensy microcontroller with tape and that's it. I inserted a flash drive / mouse - after 60 seconds you are hacked. If there is a directive not to connect unfamiliar flash drives to the computer, then no one forbade connecting the mouse to the computer.

    Netragard’s detailed attack report is published as a result of a recent U.S. Department of Homeland Security study that found that 60% of employees who discovered drives or USB sticks in the parking lots of government buildings and private contractors immediately connected them to their computers.

    imageLogitech in 2009 stated: “Since the displacements of a mouse would not give any useful information to a hacker, the mouse reports are not encrypted.”

    Chinese hackers, researchers in their work Password Extraction via Reconstructed Wireless Mouse Trajectory showed how to simplify the work of an attacker by collecting data from a wireless mouse. Researchers claim that many random number generators use information about the movement of the mouse, and if you have this information, it reduces entropy. Researchers also say that they can identify the user, understand what applications the person uses and even get a password.

    Intercepting data on the mouse path on the screen opens up the possibility for a “prediction attack” (prediction-based attacks) to predict where the victim will click on the virtual keyboard. The password accuracy is 95%.

    The authors of the article argue that the vulnerabilities of wireless mice are clearly underestimated and ignored by manufacturers and call for paying attention to user safety.
    Well, we'll wait for the paranoid mouse with an encrypted channel.

    Cutting Roccat TYON


    Here's what's inside a regular ball mouse:



    For me, it was the discovery that optical sensors are used in a ball mouse.

    What is inside this mouse here I’m even afraid to imagine:

    It’s a pity to saw the mouse in half, so I wanted to unscrew it humanly. But it wasn’t there, the cog-bolts are not visible at all.

    There was an idea that now they do not use bolts and I tried to pick it with a screwdriver. Did not work out. I began to search further - I found them under the overlays.


    As it turned out - not all. But the screwdriver completed its work and the mouse with a crunch, but the


    insidious bolt was opened hid under the sticker






    LED wheel illumination. The mouse is simply crammed with LEDs and light guide pads. It looks cool, especially in the dark. The girls are thrilled.

    User retention has become relevant for mice. Use our product a lot - get a trophy. They are given for mileage / clicks / scrolls - that is, simply for the use of the mouse itself.

    A bit of history


    image

    XEROX chip for motion detection.

    The first optical mice appeared in 1980, at MIT and Xerox, one of them worked in the IR, the other in the visible spectrum. The mat was one of a special composition for IR on metal, and the other was printed on paper. The mice had a different algorithm - one coordinate grid was attached to the rug and it went crazy if the rug was turned, the second took measurements relative to itself.

    The first laser appeared in 1998 in the dungeons of Sun Microsystems, and Logitech released the MX1000 in 2004. Using a laser gave mice extra positioning accuracy, responsiveness and the ability to use on many different surfaces.

    A little later, Logitech upgraded the system so that you can use the mouse on transparent surfaces: The


    light beam is directed perpendicular to the surface, which eliminates distortion on transparent surfaces

    Interesting instances of homemade mice


    Inquisitive minds are not asleep and constantly think how to gash their supermouse.

    Project with Kickstarter . The mouse reads the parameters - like heart rate and skin resistance - to reveal the most cold-blooded Jedi.

    A hacker reads a fairy tale to his grandson:
    - "... he began to click a goldfish ..."
    - Grandfather, why a fish?
    - And so, my friend, there were no mice then.
