Is someone spying on your WhatsApp? Here's how to confirm
03 Aug 2025

Despite its robust security features, including end-to-end encryption and privacy-first policies, WhatsApp is not entirely immune to snooping.

Your account can be compromised by spyware, malicious apps, or even a leaked QR code access.

This article will provide you with a practical guide to identify signs of potential snooping on your WhatsApp account and how to secure it effectively.

Check for these signs
Indicators

There are several signs that could indicate someone is spying on your WhatsApp account.

These include messages being marked as read without your action, chats with unknown numbers appearing in your history, and outgoing messages you didn't send.

If you notice these unusual activities, check the "Linked Devices" section under WhatsApp settings to see if any unfamiliar devices are connected to your account.

Phone behaving strangely?
Device anomalies

If your phone is acting strangely, it could be a sign of spyware.

Look out for things like overheating without heavy usage, unusually fast battery drain, lagging or crashing when opening WhatsApp, and strange vibrations or notifications.

You can check the battery or RAM usage settings on your phone to identify any unknown apps that may be consuming resources.

Are your calls being intercepted?
Call concerns

If you hear strange static, echoes, or background noise during WhatsApp calls, it could mean someone is listening in or recording them.

To confirm this, use another phone to test the call quality. If the issue persists only on your device, it may be compromised.

Check for suspicious apps
App scrutiny

Apps that ask for unnecessary permissions like location, storage, or microphone access could be data harvesters. This is especially true for unofficial WhatsApp "modded" apps.

If you find any such app on your device, uninstall it immediately.

Take these steps to secure your account
Security measures

To secure your WhatsApp account, enable two-step verification by going to Settings > Account > Two-step verification > Enable.

You should also log out of all active WhatsApp Web sessions by going to Settings > Linked Devices > Log out from all devices.

If you suspect a SIM or device breach, consider changing your WhatsApp number but remember that this will erase chat history unless backed up.

Other preventive measures
Further precautions

You can also disable location sharing by going to Settings > Privacy > Location and turning it off temporarily.

Using a VPN can help mask your IP address and location data.

Keeping your app and operating system updated with the latest security patches is also important as they fix vulnerabilities that hackers exploit.

Finally, consider installing a reputable antivirus app like Bitdefender, Norton, or Malwarebytes to detect and remove hidden spyware on your phone.
