Are mouse jigglers detectable? An honest answer

Short answer: often, yes. And any product that tells you otherwise is making a promise it cannot keep.

We make a keep-active app, so we have an obvious interest in this question. That is exactly why we want to answer it straight. This page explains how monitoring software spots jigglers, what happened when a large bank went looking, and what that means for you if all you want is to stop Teams or Slack from marking you Away while you read or take a call.

Three ways jigglers get spotted

Employee monitoring vendors publish their detection methods openly, because it is a selling point for them. Their descriptions fall into three groups.

1. Movement that looks like a machine

Human mouse use is messy. Speed, direction and timing vary constantly. A jiggler moves the same way, at the same interval, for hours. Teramind's guide says jigglers "create unnaturally consistent and repetitive activity" and recommends analysing "speed, acceleration, click rate, and mouse cursor trajectory" against a baseline for each employee or role (Teramind).

CurrentWare ships this as a feature. Its jiggler detection analyses mouse movement patterns and flags input that does not look human, such as "repetitive or continuous movement over long periods", and records it on a timeline for the admin. It is disabled by default and has to be switched on (CurrentWare knowledge base).

Time Doctor describes a related signal: long stretches of mouse movement "with no input or interaction", especially "when paired with high idle time and low keyboard activity", and comparing activity data against screenshots (Time Doctor).

2. The hardware itself

A USB jiggler is a physical device that announces itself to the computer the moment you plug it in. Security vendor Sepio says it "detects the mouse jiggler as an unauthorized USB Human Interface Device (HID)" by "identifying the actual hardware connected to an endpoint rather than relying solely on observed user activity", and that "hardware fingerprinting can reveal unauthorized devices even when they imitate legitimate peripherals" (Sepio). Time Doctor likewise says USB jigglers are "more detectable through device-level monitoring and endpoint protection tools" (Time Doctor).

3. The software on your machine

A software jiggler is an app, and apps are visible to the computer they run on. Time Doctor notes that software jigglers are "still traceable by tools that log application usage or monitor background processes" (Time Doctor). On a managed work laptop, IT can usually see which applications are installed and running, and can block installs entirely.

These are vendor claims, and none of these pages publishes accuracy figures. Teramind itself hedges that repetitive motion "may signal" a jiggler and that not every pattern means one (Teramind). But the direction is clear: detection is an active product category, and it keeps improving.

What happened at Wells Fargo

In 2024, Wells Fargo fired more than a dozen employees in its wealth and investment management unit. According to Bloomberg's report, regulatory disclosures filed with FINRA said they were "discharged after review of allegations involving simulation of keyboard activity creating impression of active work" (Bloomberg via WealthManagement.com, June 13, 2024).

The detail that matters is the wording: simulation of activity "creating impression of active work". The problem was not a tool. It was using a tool to suggest work that was not happening. That distinction is the whole ethical question in one sentence.

No tool should be called undetectable

You will find jigglers marketed as invisible to IT or impossible to detect. Be skeptical of all of them, including us. Here is why:

• Software on a computer can see other software on that computer. Any app that generates input runs as a process, and endpoint tools can list processes.
• A synthetic input event is still a synthetic input event. Input posted by an app goes through the operating system like any other event, and nothing stops monitoring software on the same machine from watching for it.
• Policies matter more than technology. Even if nothing flags it today, using a tool your employer prohibits is a policy problem, not a technical one.

So the honest advice is simple: check your workplace policy, and follow it. If your employer bans activity simulation, do not use a jiggler or anything like one on a work machine. If your employer is fine with it, or you are self-employed, you have nothing to hide in the first place.

What we built, and what we do not claim

Stay Green exists for a narrower, more honest problem: the false Away. You are working, just not touching the machine that runs Teams or Slack. You are reading a document, watching a training video, taking a call on your phone, or working on a second computer. Teams flips you to Away after about five minutes of inactivity (Microsoft Learn), and Slack after ten (Slack Help Center).

Here is how it is designed, stated plainly:

• It never moves your cursor. It sends one harmless keypress (F20 by default, a key no Mac keyboard has) and a zero-distance mouse move to reset the system idle timer. We chose this because a drifting cursor is annoying and gets in the way when you share your screen.
• It only acts when you are idle. While you are typing, it does nothing at all.
• It pauses itself outside work hours. The off-hours pause is on by default (9 to 5 on weekdays, adjustable in Settings), so it stops at the end of your day. It is not a tool for showing green at midnight.
• Nothing about your activity leaves your Mac. It never reads or logs your keystrokes and never looks at your screen.

And here is what we do not claim: we do not claim Stay Green is invisible to monitoring software, harder to detect, or safe to use against your employer's rules. It is an app running on your Mac, and the input it sends is synthetic. If your company's tools look for that, they can find it. Use it the way it is meant to be used: to cover genuine work time, within your workplace's rules.

If that is what you need, there is a 14-day free trial and pricing on the homepage. For a side-by-side of the options, see Stay Green vs mouse jigglers and keep-awake apps or a mouse jiggler alternative for Mac.

FAQ

Can my employer tell if I use a mouse jiggler?

Often, yes. Monitoring tools look for repetitive cursor patterns (Teramind, CurrentWare), unknown USB devices (Sepio) and background processes (Time Doctor). Whether your employer runs these tools is something only your employer can tell you.

Are hardware jigglers safer than software ones?

Not in any meaningful sense. Software jigglers show up as running apps, and USB jigglers show up as connected hardware that can be fingerprinted (Sepio).

Did people really get fired for this?

Yes. Wells Fargo fired more than a dozen employees in 2024 after reviewing allegations of "simulation of keyboard activity creating impression of active work", according to FINRA disclosures reported by Bloomberg (WealthManagement.com).

Is Stay Green harder to detect than a jiggler?

We do not claim that, and you should not assume it. Stay Green avoids cursor movement for usability reasons, not to evade anyone. Follow your workplace policy.

What can I do instead of a jiggler?

Set an honest status with a duration, lengthen your lock timer if allowed, or run your chat app on the device you are using. See why Teams says you are Away when you are working and how to fix Slack's 10-minute inactive rule for every option, free ones first.
