This scary AI recognizes passwords by the sound of your typing::British researchers have trained an artificial intelligence to recognize keystrokes by sound. A smartphone placed near a laptop served as the microphone.

    This news has been reported for months in increasingly sensationalist headlines. The short version is that you only have to worry if you are a slow typist in a high-espionage setting in which your system is physically secure so no one could use a physical or digital keylogger attack, but also has a sample of your typing and audio recording access to your computing area.

    Old recycled news.

    Last time: If you know the model and way of typing of the target you have a good likelyhood.

    Does it recognize backspace, select all delete, a few curse words, slamming the desk and then the phrase “that’s what I fucking typed the first time!”

    That’s why I have 7 different brands of switches all different types on my keyboard.

      Or if you want to go further, have foamed + plate mount + mixed lubed and unlubed switch + different color of switch on top of mixed brands of cherry mx, kailh, gateron, outemu and or lesser known/premium switches on single keyboard, the cost may be unusually high and need custom printed pcb.

      Maybe you’ll need to get use to typing on it as now comprised of various tactility and feedback feel.

    Wouldn’t it only be trained on a specific keyboard though, as anyone in the Mechanical keyboard community knows every keyboard sounds different. And that doesn’t even account for age, condition(dust, how many crisps have you eaten over your keyboard, etc).

    So I highly doubt this could be effective beyond possibility being trained to work with a certain type of laptop. 16 inch MacBook Pros for example.

      Doesn’t matter that much if you cast your malware broadly enough, for example requesting mic access from a web page. A large percentage of keyboards (especially business laptops) will be covered just by Mac + Lenovo.

      Because all keys on a keyboard sound slightly different, computers can detect those differences, and compare it with a baseline from either the same keyboard or a model just like it.

      Try this: on any keyboard (a membrane keyboard especially if you have one) try quickly tapping one key 3 times and then another key 3 times. Move around the keyboard or alternate between two letters.

      Can you hear that they make different sounds, but typing the same letter has roughly the same sound? The" plok" has a higher or lower pitch (frequency is the scientific word for it), and a trained AI can match that pitch to a letter if it has or can get an idea of what corresponds to what.

    So… at what point will paranoid people start screaming at their keyboards while typing, “just in case”?

      The layout is less of an issue, as long as the program analyzing the sounds of your keyboard can diferentiate between all keys, then it can remap to QWERTZ, AZERTY or sny other layout.

      However, this attack seems quite involved, so if you are targeted, the attacker could find out the layout in use ahead of time (here in Sweden you are unlikely to find a person using anything but a Swedish layout), they could also fo some social engineering, and hold a chat conversation with you while using your phone to record keystrokes, it would take a while, but over time they could probably get a decently accurate map of your keyboard.

      Wouldn’t it also be able to crack it in the future as long as it’s accurate enough? As long as it’s able to accurately recognise what key is which it can crack it like the enigma code.

    I feel like you could type really slowly to throw it off. How would it know the distance to each key if you set a standard interval between each one?

    I once recognized the sounds of a girlfriend deleting texts by where her nail was hitting her phone screen in a specific pattern. That is more sad than impressive, I understand. Just saying that this makes sense and is not beyond human capability on its own.
