Quiet spying#
Unlike ransomware, spyware doesn't reveal itself. Its goal is to stay invisible as long as possible while collecting information: what you type, where you go, where you are, and who you talk to. Some types also target the microphone, camera, or messages.
Common types#
- Keyloggers, which record the keys you type.
- Hidden tracking apps on phones.
- Browser extensions that sell your history.
- Apps that ask for contacts and SMS permissions for no reason.
An important note about monitoring in personal relationships#
Sometimes spyware is installed by someone close, such as a spouse or a coworker. Doing this without the other person's consent is unethical and may be a crime. If you think someone has had access to your phone, take it seriously.
How can you tell?#
- Battery and data are being used heavily for no reason.
- The phone is overheating or has slowed down.
- An unknown app appears in the accessibility list or device administrators.
- An app has a permission it shouldn't need.
Protection#
- Use a strong screen lock and don't hand your phone to others.
- Install apps only from official sources and review permissions.
- Keep the operating system updated.
- If in doubt, use an anti-malware tool and, as a last resort, factory-reset the phone (after safely backing up your data).
