Bug Corsair Keyboards Type Own Digital Risk Firmware

A company spokesperson responsible for producing Corsair keyboards has confirmed that a flaw in the firmware of their K100 keyboards is the cause of typing on its own.

The company’s announcement materialised after numerous K100 keyboard users reported a bug in which the keyboards are auto typing at random moments. The incident was first reported by users to the Corsair forums last August. During those times, people were sceptical about whether the bug was caused by malware or a keylogging attack.

However, a Corsair representative responded to the concerns, assuring everyone that the keyboards do not have keylogging features, nor have they identified malware activity within their devices.

 

The issue on the Corsair keyboards is not malware but a bug on its macro recording.

 

According to the keyboard manufacturer, the problem of the Corsair keyboards comes from a vulnerability in its macro recording feature that causes it to switch on by mistake and start recording keystrokes and mouse movements.

Subsequently, these macros will be activated later, which could cause the saved text to be typed again by the keyboard.

However, the most recent firmware update the company made available for the K100 keyboards did not address the issue. Furthermore, the latest update has caused numerous freezes on the keyboard, which some owners report may be linked to the high polling rate setting.

According to the company, the best way to deal with the current issue is to reset the keyboard by unplugging it and long-press the Esc button for five seconds before plugging it back into a device.

Unfortunately, some users said that the factory reset and keyboard memory-clearing strategy still did not prevent the problem from happening again. As of now, users would have to wait until Corsair disseminate a new firmware update that would patch the flaw.

Experts claimed that repeating randomly captured inputs might cause exposure of information in screen sharing and presentation. In addition, the bug could interrupt a user during gaming hours. Therefore, it is wise for users to replace the Corsair keyboards while waiting for a patch to address the issue.
