Corsair says K100 keyboard's weird behavior is a bug, not a keylogger

A hot potato: Some users are reporting a weird issue with their Corsair keyboards, which have started to behave like reverse keyloggers. Rather than silently logging keystrokes, chunks of text written days before suddenly appear again on the screen. It certainly is a bug, Corsair said, not a "secret" keylogging feature.

Corsair Gaming is having a bit of a privacy nightmare right now. Owners of the Corsair K100, an expensive mechanical keyboard aimed at gamers, comes equipped with several "extra" features but users are reporting that their peripherals have started to behave like a weirdly malfunctioning keylogging device.

The first issues with the K100 were reported on Corsair's official forum in August, while the latest ones are just a few hours old. The very first affected user said their K100 keyboard "started randomly typing on its own" while the device was connected to a MacBook Pro. "It usually seems to type messages that I previously typed" on a gaming PC, the user said, and it wouldn't stop until the keyboard was unplugged and then plugged back in.

Other users joined the thread, denouncing they had a very similar experience. One user said the K100 was replicating chunks of text previously written in a "very sensitive email" while the PC was in Safe Mode. Another person complained about the fact that their keyboard "wrote" more than 100 letters all by itself.

One user noted that they don't use Corsair's iCue gaming software to program the keyboard behavior, so the keylogging-like "feature" seems to be a hardware-related issue. Some customers feared they were hacked by unknown malicious software, but according to Corsair "there's no hardware function on the keyboard that operates as a key logger."

Like many other high-end keyboards, the K100 features the ability to create "macros" by recording inputs – but it's a totally user-driven option, Corsair assured. "The macro function could be inadvertently switching on and recording keyboard, and potentially mouse, inputs," a Corsair spokesperson said, and these macros were then being "triggered and reproducing inputs at a later time and misinterpreted as keylogging."

The company said that they received just a "small number" of complaints compared to the "tens of thousands" of units sold to date. While still investigating the "precise nature" of the issue, Corsair recently released a new firmware update which seems to solve the keylogging issue – but users have lamented the fact that the update brought other issues as well.

Corsair said any affected user should contact the company's support team and try to reset the K100 by unplugging it then holding down the Esc key for five seconds (while plugging it back in). "Corsair takes customer data privacy very seriously," the spokesperson added, and even if a single user is impacted, they will "quickly work to resolve the issue."

Any company who admits their product was designed in a malicious way is doomed, so they literally must say it’s not a keylogger. Corsair would never admit this, regardless of if it’s true. If it was true, they are certainly better off lying.

I don't know why, but I believe Corsair 100%.
I do too, I mean what company would want their product to be used in a malicious way? That said, a 3rd party should investigate this because I wouldn’t trust any company to admit the truth about this if their product somehow happened to function in a malicious way out of the box.

Yes trust the million dollar corporation that has a vested interest in collecting and selling your data, they would NEVER EVER lie.

Such an obvious bug should have been caught in testing. How would a keyboard be able to type out words at all, if its not capable of storing them? Highly suspicious.

Can't wait till they fix the M65 mouse USB bug in which the mouse randomly doesn't power on when you first boot the system (not detected by Windows). I have to unplug it and plug it back in again and it'll work fine. I own 6 of these mice in my house and they ALL do it across a variety of systems (laptops, desktops, mac mini, etc). Gotta love it.

My HyperX keyboard was doing something similar about a month ago. Random keys being typed like it was in turbo mode. The backlit key mode rapidly changing, different windows being rapidly selected, nothing would stop it, had to unplug it and switch keyboards. I thought my system was compromised. Still unsure. Any other issues with other chinese keyboards?

Typing this on a K100... so far I haven't had this problem. Given how craptastic their iCue software is, it wouldn't surprise me that it's a bug. My guess is that their software is probably written and maintained by interns.
