Can ActivTrak Detect a Mouse Jiggler? Yes, in Three Ways

Yes, ActivTrak can detect a mouse jiggler, and it says so in its own help center. Its Potential False Activity guide describes three checks: it recognizes known jiggler apps running on the computer, it spots uniform input patterns from software or USB jigglers, and it flags anyone who stays on one screen for more than 45 minutes. When it sees a repetitive pattern, ActivTrak takes that time out of the activity reports at once. The guide says this happens "whether or not the alarm is turned on."

So a jiggler does not make ActivTrak count you as working. It more often produces a record that you used one. Most people reach for a jiggler to keep a chat status green, not to fool ActivTrak.

The three ways ActivTrak detects a mouse jiggler

ActivTrak calls this Potential False Activity, or PFA. Each check has its own alarm, and ActivTrak gives each one a confidence level for a single event.

Input Simulation Software. ActivTrak keeps what it calls a "continuously growing, crowd-sourced database of known mouse-jiggling software." If one of those apps is running, the Activity Log gets a line such as "Input Simulation Software Detected - artificial input apps running in the background: Move Mouse.exe". The app only has to be running. ActivTrak notes it does not confirm the app was moving the mouse at that moment.

Repetitive Activity. This check looks at the input itself: "keys being held down, clicks occurring at regular intervals, or mouse movements that repeat in a consistent pattern." A USB jiggler that moves the pointer the same way every 30 seconds looks like that, even though no app is installed. The guide says it "catches both software- and hardware-based patterns." The same regular-interval test, as a 30-line script anyone can run, is in how to detect a mouse jiggler.

High Duration Activity. ActivTrak's data says real people rarely stay on one screen for long. It sets the default at 45 minutes, based on "more than 9,500 customers." A jiggler parked on one window hits this, because a jiggler never switches windows.

When alarms repeat, ActivTrak rates the evidence higher. More than two Repetitive Activity alarms a day over a week rates 90%, and both Repetitive and High Duration together rate 95%.

What happens after ActivTrak flags you

The three alarms are off by default. An admin turns them on under Notifications, Compliance Alarms, Alarm Configuration. The reclassification of repetitive input is not an alarm, though. It runs on every account.

• • Agent 8.6.7 and newer. The time of the repetitive activity is "excluded from all standard reports" and shows as white gaps on the day's timeline.
• • Older agents. The activity switches from active to passive, and after the 5-minute timeout it becomes inactive, again white gaps.
• • The Activity Log records every detection. An admin can search the Description field for "artificial input" to see every flagged event in the last 30 days.
• • Screenshots, if the company pays for them, can be set to fire with these alarms and keep taking pictures every 10 seconds or more while you stay on the same window.

ActivTrak's advice to employers after a confirmed software detection is to notify HR and IT, block the tool, and have a manager raise it under the company's technology policy. Whether that can cost you your job is covered in are mouse jigglers legal.

"Repetitive activity detected" and "potential false activity" meaning

Potential false activity is ActivTrak's name for any input that may not come from a person. Repetitive activity detected is the message for the second check above: ActivTrak saw input that repeats too evenly and stopped counting that time as active.

A false alarm is possible. ActivTrak itself published a known issue in which Windows agents 8.6.7 and 9.0 raised more Repetitive Activity alarms than they should, including back-to-back entries for one session. Long video calls, remote desktop sessions and holding a key in a game or a spreadsheet can also look uniform. If you are flagged for something you did not do, ask what the Activity Log and screenshots show; ActivTrak tells admins to check at least five incidents before acting on patterns.

What ActivTrak tracks, and what it does not

ActivTrak's page What Data Does ActivTrak Collect lists every field. It defines activity as "mouse movement, mouse clicks and keyboard presses from the currently active window."

Does ActivTrak track keystrokes? It counts that you pressed keys, because that makes you active. It does not record which keys. ActivTrak lists keystroke logging and webcam monitoring under "Data never collected."

ActivTrak screenshots. Screenshots need the paid Screen Details add-on, are off by default, and are always triggered by an alarm. A multiple-screenshot alarm takes one every 10 seconds or more until you switch windows, go passive, or reach 100 shots for that activity.

How ActivTrak compares with other tools is in how do employers monitor remote workers, and how to find out whether it is on your computer is in how to tell if you are being monitored at work. DeskTime, which has no documented jiggler check, is covered in can DeskTime detect a mouse jiggler. Insightful runs a similar check once per shift; see can Insightful detect a mouse jiggler. The Active, Passive and Inactive timers behind those gaps are in ActivTrak idle time.

Can any mouse jiggler get past ActivTrak?

Some, some of the time, but none is safe to count on. ActivTrak says that "some sophisticated hardware might occasionally slip past detection," and it does not see USB devices directly. A mechanical platform or a USB jiggler with random timing avoids the first check and may avoid the second. None of them avoids the third: a jiggler never changes windows, so after 45 minutes on the same screen the High Duration alarm flags it, if the company turned that alarm on. If screenshots are on too, they show a screen that does not change.

Jiggler apps that call themselves undetectable still run as a process, so the software check still has something to find. The wider picture, including what IT sees on a managed laptop apart from ActivTrak, is in can a mouse jiggler be detected.

If what you want is a green dot in Slack

A jiggler is often the wrong tool for Slack too. The Slack desktop app counts keyboard and mouse input anywhere on the computer (Slack desktop 4.52.178 code, checked 7 Oct 2026), so a jiggler keeps your Slack dot green too, while the computer is awake and unlocked. Teams is different; see does a mouse jiggler work for Teams.

The ways to keep the Slack dot green without a jiggler are compared in how to keep Slack active. ActivTrak records your real activity whatever your Slack status shows.

FAQ

Can ActivTrak detect a mouse jiggler? Yes. It recognizes known jiggler apps, flags uniform input from software or USB jigglers on Windows, and alarms after 45 minutes on one screen.

Can ActivTrak detect a USB mouse jiggler? Often. It does not see the USB device, but the Repetitive Activity check reads the input pattern on Windows, and the High Duration check works on every platform.

What does "repetitive activity detected" mean in ActivTrak? ActivTrak saw input that repeated too evenly to come from a person and stopped counting that time as active.

Does ActivTrak record keystrokes? No. It counts key presses as activity but does not log what you type.

Does ActivTrak take screenshots? Only if your company bought the Screen Details add-on and set up an alarm that takes them. They are off by default.

Do the jiggler alarms have to be turned on to affect my time? No. The alarms only send notifications. Repetitive input is reclassified on every account.

How does ActivTrak compare with Teramind? Teramind also flags jigglers, through its OMNI anomaly feed, and it can record the screen for later playback; see can Teramind detect a mouse jiggler.
