How to check for eavesdropping on WhatsApp (iPhone) - in detail?

To ensure the security of your communication on WhatsApp using an iPhone, it is crucial to be vigilant about potential eavesdropping activities. Here are some detailed steps and tips to help you identify any signs of unauthorized access or surveillance:

1. Check for Unusual Activity:

   • Unexpected messages or calls from unknown numbers can indicate that your account has been compromised.
   • Sudden changes in the status or profile picture without your knowledge are red flags.

2. Verify Two-Factor Authentication (2FA):

   • Ensure that 2FA is enabled on your WhatsApp account. This adds an extra layer of security by requiring a verification code sent to your phone number.
   • If you receive unexpected 2FA codes or prompts, it could mean someone is trying to access your account.

3. Inspect Device Settings:

   • Go to 'Settings' > 'WhatsApp' and check for any suspicious settings or configurations that you did not set up yourself.
   • Look out for unusual app permissions or changes in your device’s overall settings.

4. Monitor Data Usage:

   • Keep an eye on your data usage. A significant increase without a clear explanation could suggest that someone is intercepting your messages or calls.

5. Update WhatsApp Regularly:

   • Ensure you are using the latest version of WhatsApp. Updates often include security patches and improvements to protect against known vulnerabilities.

6. Check for Malware:

   • Run a comprehensive antivirus scan on your iPhone to detect any malicious software that might be monitoring your activities.
   • Be cautious about downloading apps from untrusted sources or clicking on suspicious links.

7. Use End-to-End Encryption:

   • WhatsApp messages are encrypted end-to-end by default, ensuring that only you and the recipient can read them.
   • Verify the encryption status in your chat settings to make sure it is active.

8. Review Linked Devices:

   • Go to 'Settings' > 'Linked Devices' on WhatsApp to see a list of devices where your account is active.
   • If you find any unknown or unfamiliar devices, immediately log out from those devices and change your password.

9. Use Biometric Security:

   • Enable Face ID or Touch ID for added security when accessing WhatsApp on your iPhone. This prevents unauthorized access even if someone has physical access to your device.

10. Be Cautious with Public Wi-Fi:

    • Avoid using public Wi-Fi networks for sensitive conversations, as they are more susceptible to interception.
    • Use a secure VPN service when connecting to public networks to encrypt your data traffic.

By following these steps and remaining vigilant, you can significantly reduce the risk of eavesdropping on your WhatsApp communications using an iPhone.
