Stalkerware Spy App Hidden on a Phone is one of the ways this shows up: A hidden spy app can show messages, location and calls to someone who installed it. Learn the signs and how to check your phone safely.

What stalkerware spy app hidden on a phone looks like by SMS

• A sender name that resembles a bank, courier, tax or utility, or an ordinary mobile number.
• A very short message with a deadline such as "today" or "within 24 hours".
• A shortened or oddly spelled link that does not match the real website.

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 text 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.
• The link domain is not the one you type yourself for that organisation.
• The message asks for an OTP, PIN, card number or password.

What to do

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. Paste the text into a scam checker (Safeavio Sentinel can check it) before you do anything else.
5. Report the sender on the Sanchar Saathi portal (Chakshu facility) and block the number.
6. Delete the message and tell family members who may get the same text.

You can report suspicious SMS and calls on the Sanchar Saathi portal (Chakshu facility) of the Department of Telecommunications.
