In “end to end encryption method” data is encrypting before transferring to the other user and ultimately decrypted after the delivery of the message by the built-in decryptor of the messenger app.
Although, it is somewhat secure to communicate through WhatsApp despite there are still vulnerabilities to your privacy which are worth noticing to update your privacy settings.
The vulnerability of data in the device
It is true that in WhatsApp, your data is protected with end to end encryption but your device might still be vulnerable before encryption and after decryption of the data.
If you are somehow tricked to install spyware on your mobile, your data can be easily mined and sent to the external server.
So, you must be very careful while installing any software or application on your mobile. You should never use the application and software from unknown resources.
Is Your Data Encrypted in Backup
WhatsApp says that after the delivery of a message, it is removed to alleviate the burden from the server but these files can remain in mobile storage.
Many times, we delete these files from the WhatsApp and Gallery but if the auto-backup function is turned on, our files can still be accessed by data miners from backups as files in backups storage are not encrypted from end to end.
So, if you want to make your privacy secure, you can turn off the auto backup function.
Using WhatsApp Web
WhatsApp web is also another feature of WhatsApp in which you can use WhatsApp on the desktop by scanning the QR code from the WhatsApp mobile app.
Many People don’t care about their WhatsApp active sessions on the desktop which can be misused.
Therefore, you should use the WhatsApp web on a secure the browser and make sure that you turn off all the web sessions when you are no more using WhatsApp Web.
Don’t Be Careless about Delete for all Function
People usually send messages carelessly thanking to delete for all function. Yes, delete all functions works within one hour after sending a message.
But no guarantee can be rendered that deleted messages can’t be accessed by anyone because there are several other third-party applications available that can trace a text snippet from the notification of the received message.
Also, a person seeing your message can take the screenshot of your message and you can no more deny such messages.
Keeping in view the safety of your privacy, you must make sure that you don’t send or share any kind of content on WhatsApp which might be regretful for you.
WhatsApp cannot be HACKED?
Although WhatsApp has a strong security system to make your privacy safe, it can not be claimed that WhatsApp application can’t be hacked.
Many times WhatsApp data has been stolen by the cybercriminal agencies such as Spyware attacks by NSO Groups.
So, you should never be careless about your privacy as it is never a pleasant experience when your private data is stolen or exposed.
Instead of this, you should follow the protective measures to ensure your privacy such as updating your operating systems and installing strong anti-virus software, changing your privacy settings, etc.
