Silencing AirTags enables stalkers and domestic violence

ElevationLab has released an AirTag product I find appalling, and I strongly urge they immediately withdraw it from sale and recall all inventory. The AirTag Silencer is a simple device: remove the back panel and battery from an AirTag, position the Silencer’s highly engineered pin over the speaker, tap the pin with a hammer, and the AirTag’s speaker is destroyed. This prevents it from emitting an alert in three circumstances, only one of which is triggered by an owner. The other two scenarios aid stalkers and perpetrators of domestic violence, among others. I will not link to it.

Disabling an AirTag speaker is a way for an unwanted party to more easily track someone without their knowledge and consent. Apple designed the AirTag to alert people when an unknown tracker was moving with them (via software), or when a tracker moved or was bumped (via a sound) after remaining in a location for a period of time. The latter case is critical, as Find My items have been found in purses, luggage, vehicles, and other things that move, left there either provably or putatively by a party attempting to track someone otherwise unaware they’re under remote observation.

You can find sites selling AirTags with the speaker disabled all over the Internet, as well as instructions to do so, and some even state outright that the action helps with unwanted tracking. ElevationLab’s AirTag Silencer is certainly the only mainstream device that performs this task with the exacting design one has come to expect from the company since the introduction of their 2012 iPhone dock—now with the proviso of “unfortunately.”

I’ll take ElevationLab at their word that they intend this for use with, as the product description states, “Anything you wouldn’t want the speaker tipping off a thief. (We originally designed this for our own bikes that have been stolen).” This also guided their 5-year and 10-year AirTag cases, which can be secreted in a hard-to-remove location deep within something expensive.

It is true that the “moving with you” and audio alerts make an AirTag and similar items less ideal for recovering stolen items than for finding lost ones, tracking luggage in transit—or being alerted that you left something behind.

Eva Galperin, Director of Cybersecurity at the Electronic Frontier Foundation, was blunter than I. “Honestly, this is just another example of the mindset that things are more important than people,” she said via email. “There is a reason why the AirTag makes that noise, and it is because you cannot make a tracker that does not alert a thief without also making a person a tool for stalking. I think these people have, in fact, considered the implications and decided that they don’t care.”

I posed the question of potential misuse to Casey Hopkins, ElevationLab’s CEO. He replied via email, “We make products we want for ourselves. And we’ve had expensive bikes and other gear stolen and then recovered using AirTags. We have also silenced our own AirTags on those items using DIY methods available online and on YouTube. If someone is determined enough, they could already silence it themselves, but the person would still get phone notifications. With roughly 200 million AirTags in use, extreme edge cases will make news, but the overwhelming number of people just want to track their own gear.”

I see his point, but I don’t accept it, as the viewpoint is either naive or uninformed about the scale of abusive tracking. Yes, AirTags are used mostly for good purposes—my family must own 20 Find My items at this point—but there’s a difference between what a product might be used for and making a tool that expedites bad behavior, disabling both a component and a strategy created by Apple. Making it easy to remove the speaker also makes it simpler to engage in consent-free tracking—there are no two ways around it.

Silent tracking

Apple’s Find My items and Google’s Find Hub trackers securely relay a signal from trackers through nearby iPhones, iPads, and Macs (Apple) and Android devices (Google), letting us keep tabs on our stuff and then potentially find it when it’s lost or stolen. The AirTag is a sword with two edges: one allows desired finding by yourself or others you share an item’s location with; the other, privacy-invading stalking, is often employed by those attempting to control someone, as part of ongoing domestic violence or stalking an acquaintance or stranger.

This isn’t speculative. You can find hundreds of newspaper articles and television reports about specific cases, and many write-ups of the broader problem. In New South Wales, Australia, a local commission on crime was able to compel retailers to provide information about who purchased tracking devices in 2023. Their analysis revealed one in four of the purchasers—about 750 of 3,000 people—”had a history of domestic violence, while a further 126 were apprehended violence order defendants at the time the items were purchased.” A lawsuit filed a few days ago in Oregon is the latest example.

The speaker is a primary component of the company’s anti-tracking strategy, so much so that the second-generation AirTag, released this year and replacing the original, emits a 50% louder sound. While that aids in finding stuff you’ve misplaced, it definitely increases the likelihood that a victim of stalking will hear an alert sound. Apple and Google, not notable collaborators, worked together in 2023 to release an anti-stalking proposal, which both companies have adopted, including audio alerts.

Apple originally had an AirTag (and third-party devices certified as Find My items) emit a sound when it was moved after three days in the same location. Advocates for victims of domestic violence and groups concerned with privacy urged a shorter time period. Apple updated the alert, just a few months after the product’s 2021 release, to trigger at a shorter and random interval. Since mid-2021, an AirTag or any Find My item chirps when moved between 8 and 24 hours after its paired device was last within Bluetooth range; the randomness makes it harder for a tracking party to predict when it might make a sound.

If you have an iPhone, iPad, or Android device and an Apple or Google tracker moves with you for a short period of time, your device will alert you and provide a map of where you’ve been tracked so far. This also lets you play a sound on the tracker device—something that’s not possible if the speaker has been removed.

Not being a lawyer, I can’t argue whether or not ElevationLab’s product comes with liability. However, using an AirTag, Find My item, or Google Find Hub tracker to acquire the location of someone without their permission may be a crime or risk a lawsuit, depending on the jurisdiction.

There are different ways to disable an AirTag or other tracker you discover, typically by rotating the back case and removing its battery. EFF’s Galperin has more direct advice: “I think that encouraging people to hit their AirTags with a hammer is a fine idea. They may need to hit it several times.”

A misfired pin

I’ve been purchasing products from ElevationLab since their 2012 ElevationDock. The company has always had an eye for elegance coupled with problem-solving.

This is what makes the company’s AirTag Silencer an absolutely baffling misfire, something that you would have thought would have called out as enabling behavior by some customers that no company would want to be associated with.

ElevationLab can’t prevent speaker-removing hardware from being sold or instructions from being disseminated. But the company should not be producing a case-hardened steel piece of precision goods that may look like a pin, but is a razor-sharp double-edged sword. Pull this product from sale.
