What Is Stalkerware?
Stalkerware is a type of mobile spyware used in abusive relationships. It can secretly monitor both your offline and online activity, tracking your GPS location, reading your texts and emails, and listening to phone calls.
Stalkerware can be disguised as legitimate apps, such as calculators or system tools, or hide in background processes through malicious code. It can also arrive via malicious links, cloned apps, or dodgy sideloaded APK files.
Some early warning signs your phone might be compromised include sudden battery drain, overheating, or sluggish performance, unusual background noise during calls, apps requesting permissions they don’t need, and data usage spikes or texts you didn’t send.
What Is Mobile Software?

Early warning signs that your phone might be compromised include sudden battery drain, overheating, or sluggish performance, unusual background noise during calls, apps requesting permissions they don't need, and data usage spikes or texts you didn't send.
Stalkerware can arrive via malicious links, cloned apps, or dodgy sideloaded APK files, or even when someone has physical access to your phone. It can access nearly everything, including your text messages, GPS location, call history, browser activity, saved passwords, and device microphone.
Some common tactics used by stalkerware apps include sideloading an APK file from outside the Play Store, capturing your social media credentials through a fake login page, and sending them to a remote server. High data usage, strange pop-ups, or your phone heating up for no reason are all red flags.
If you suspect that stalkerware apps have been installed on your phone, take these first steps:
- Review what apps have access to your camera, mic, or messages in your Settings app > Apps > Permissions
- Check if any apps were installed recently that you don't recognize, especially those requiring admin access
- Avoid connecting to unfamiliar Wi-Fi networks, which can be used for spyware injection
Stalkerware can be difficult to detect, but some indicators include your battery constantly draining, your device constantly overheating, and a surge in data usage. On an iPhone, the two most likely places to find stalkerware are in the Settings app, where you can review app permissions and installed apps.
How to Detect Stalkerware
Detecting stalkerware on your device can be challenging, but there are some telltale signs to look out for.
Your battery is constantly draining, which can be a sign of stalkerware. Stalkerware software runs quietly in the background, using up extra battery and data.
Unusual behavior, such as your device overheating or constantly crashing, can also indicate the presence of stalkerware. Stalkerware can cause your device to overheat much more than usual.
Stalkerware can also be bundled with other malicious software, such as adware, which can cause pop-ups and other annoying ads to appear on your device.
To find stalkerware on your device, you can check the Settings app on your iPhone. You can also look for any apps that you don't recognize, or that have been installed recently.
Here are some indicators of stalkerware:
• Your battery is constantly draining
• Your device is constantly overheating
• Surge in data usage
If you suspect that you have stalkerware on your device, it's essential to take action to remove it.

Identifying Stalkerware
Stalkerware apps are designed to be difficult to detect, often hiding their icons even while running in the background. This can be a telltale sign that something is amiss.
Some indicators of stalkerware include a constantly draining battery, overheating, and a surge in data usage. Your device may also be running slowly or showing unusual behavior.
To identify stalkerware on your device, check for unfamiliar apps in your Settings app. Look for apps with generic icons and labels, such as "Wi-Fi Booster" or "System Cleaner." These are common names used by stalkerware apps to avoid detection.
Here are some key things to check in your Settings app:
- Apps with high-risk access, such as access to your microphone, camera, location, or SMS
- Apps that request access to your messages, even if they don't seem relevant
If you suspect spyware but can't find anything manually, install a trusted mobile security app with stalkerware detection.
Finding in Downloads Folder
Finding stalkerware in the downloads folder can be a straightforward process. Launch the My Files or Files app and click on Downloads, which contains all files that have been previously downloaded on the device.
This folder is a great place to start your search, as it's likely to contain any suspicious-looking files or apps you don't remember downloading. Review the list to see if there are any unfamiliar apps or files that catch your eye.
If you're unsure about an app, Google its name to see if others have identified issues with it. This can be a quick and easy way to determine if an app is legitimate or not.
To delete suspicious-looking files or apps, tap Uninstall to remove them. However, some apps may have device administrator permissions that prevent you from uninstalling them.
If an app has device administrator permissions, you'll need to remove them before you can uninstall the app. To do this, navigate to Settings > Security > Advanced > Device Administrators.
Here's a step-by-step guide to removing device administrator permissions:
1. From the list of apps with device administrator permissions, uncheck the box next to the malicious app.
2. Tap Deactivate this device admin app to confirm the removal.
3. Return to your list of apps and now you can uninstall the app that you weren’t able to before, along with anything else that looks suspicious.
4. Restart your phone, boot it up in normal mode, and test it out.

How Is Installed
Stalkerware is often installed through unsuspecting means, making it difficult to detect. The most common method is by installing a stalkerware app disguised as a legitimate tool, such as a cleaner or battery optimizer.
Researchers have found that abusers and bad actors use several methods to deploy spyware, including:
- Remote install via phishing links, which can trigger app downloads from third-party sites, especially on Android phones where “install from unknown sources” is enabled.
- Fake parental control apps that collect sensitive information like location, call history, or login credentials without proper consent.
- App side-loading on Android devices, where apps downloaded outside the Play Store are often less regulated and easier to disguise.
It's essential to be cautious when installing apps, especially on Android devices. The open ecosystem of Android gives more freedom to developers, but also more opportunities for invasive apps to exploit security gaps.

What Makes It Dangerous?
Stalkerware is especially insidious because it hides inside your device, accessing your personal information without your knowledge. Hackers use the data they uncover with spyware to commit identity theft, fraud, and other crimes.
Spyware can record audio or video through your device, track your browsing history or physical location, and even record everything you type. Keyloggers can even record everything you type.
Stalkerware involves someone you know installing a spying app on your device without your permission or knowledge. These types of apps can be used by jealous partners, suspicious employers, or over-anxious parents.
Stalkerware differs from other types of spyware because it doesn’t send your data to unknown cybercriminals but to someone you know personally. This is because an attacker needs physical access to a personal account, where they can see the data received from the victim’s device.
Spyware can be installed with just a few seconds of physical access, such as borrowing your phone under a pretext. It can also be disguised as harmless tools, like a battery saver or a parental control app.
Here are some common ways spyware can access your personal information:
- Your text messages
- GPS location
- Call history
- Browser activity
- Saved passwords
- The device’s microphone
