Can a mouse jiggler be detected?
It's the question everyone asks and almost nobody answers clearly. Here are the facts, no hype.
USB devices can be inventoried
A physical jiggler presents itself to the system as an input device. On company-managed machines, security software can inventory connected USB devices and flag new or suspicious hardware. It isn't done everywhere, but it's technically possible and there have been high-profile cases.
A local app doesn't travel over the network
KeepOnDuty is software that runs on your device and sends no data to any server. It doesn't appear in your Teams or Slack account, because your presence is computed from system activity, not from which app generated it. That said, on a machine with management software (MDM/EDR), an administrator could see the processes running locally.
Use it with judgement
KeepOnDuty exists for legitimate cases: keeping the screensaver away during a demo, not cutting off a long download, not losing presence while you read or sit in a call. We don't recommend using it to deceive your employer. Check your organisation's policies and act accordingly; the tool is neutral, the use is up to you.
Frequently asked questions
Can IT see if I use a mouse jiggler?
A hardware jiggler can show up as a USB device. Local software isn't transmitted over the network, but on a managed machine an administrator could see local processes. It depends on how much control your company has over the device.
Does Teams detect mouse movement?
Teams doesn't distinguish who moved the mouse; it only reads system idle time. That's why KeepOnDuty's real movement counts the same as yours.
Is it legal?
The tool is legal; how you use it under your contract or company policy is a separate matter. Use it responsibly.
