What stalkerware spy app hidden on a phone looks like on WhatsApp

• A group invite promising returns, jobs or prizes.
• A PDF, APK or image that must be opened to "see the details".
• A link that pretends to be a wa.me, courier or bank page.

The set-up needs a few minutes of physical access to your phone, or a trick that makes you install an app yourself. The installer enables unknown sources, sets a screen lock bypass or grants permissions, then hides the icon or gives the app a plain name like 'System Service'. Some are sold as 'family tracking' tools but used without the other person's knowledge and consent.

Red flags to check on the WhatsApp message

• Someone knows details of your chats or locations that you did not share.
• An unfamiliar app with a plain system-like name appears in your app list or settings.
• Accessibility or device admin permissions are on for an app you do not recognise.
• Battery, data use or heat rises without a reason.
• A file ending in .apk arrives; never install it.
• Someone asks for the six-digit code WhatsApp sent you by SMS.

1. Think about your safety first; removing the app may alert the person who installed it.
2. Use Phone scan or the settings app to look for unknown apps and special permissions.
3. Change your screen lock and account passwords from a safe device.
4. Warn the group or family, and report the number on Sanchar Saathi if it is a scam call or message.
5. Do not click links or open files. Do not send money or codes.
6. Open the chat, tap the contact name and choose Block and report.
