Have you ever had the feeling that someone knows too much about you? Maybe a jealous partner knows exactly where you went for coffee, even though you didn’t tell them. Or maybe your phone gets hot in your pocket for no reason. Unfortunately, it’s not just paranoia.
There’s a category of programs called stalkerware. These aren’t installed by unknown hackers from other countries, but often by people you know. At Altanet Craiova, we believe your privacy is sacred, so we’re teaching you how to detect these digital spies.
What is Stalkerware and who installs it?
Stalkerware is commercial software, sometimes sold under the guise of "parental controls" or "employee monitoring." In reality, it is used to spy on adults’ lives without their consent.
Unlike classic viruses that arrive via email, stalkerware usually requires physical access to the phone. Someone takes your phone while you’re in the shower, unlocks it (if they know the PIN), and installs the app in a few minutes. Then, the app becomes invisible on the screen but sends everything to the spy.
What can a spy see?
Once installed, this program has full access. It can monitor:
- Your exact location: Via GPS, in real time.
- Private messages: SMS, WhatsApp, Messenger (even deleted ones).
- Photos: Access to the photo gallery and sometimes even activation of the microphone to listen to what you’re saying in the room.
Signs that your phone is betraying you
Since the app is hidden, you need to watch out for the symptoms of the "disease":
- The battery drains rapidly: Spying consumes a lot of energy. If the battery used to last a day and now lasts only 4 hours, that’s a sign.
- High data usage: Check your settings to see how much data your phone is using. If you see massive data usage when you haven’t been on YouTube, something is sending information in the background.
- The phone is hot: If it’s burning up even when sitting on the table, the processor is working hard on something hidden.
How do you get rid of the uninvited guest?
If you suspect you have stalkerware, don’t rush to delete it right away, because the person tracking you will receive a notification that the app has been stopped. This could lead to conflict.
Here are the safe steps:
- Change all your passwords: But do this from another device (your work laptop or a friend’s phone), not from the infected phone.
- Factory reset: This is the only 100% safe method. It erases everything from your phone, including the virus. Make sure you’ve saved your important photos beforehand.
- Secure physical access: Set a complex PIN or use fingerprint/Face ID. Don’t let anyone know your unlock code.

Conclusion
Your phone should be a safe, not an open microphone. Be mindful of who has physical access to your device and don’t ignore signs of poor performance.
