how to protect WhatsApp from hacking- Knowledge World

WhatsApp chat was protected by end-to-end encryption. Even so, owning one is still beyond the reach of the average person. Because, even though there was encryption in the chat, there was no encryption in the chat backup. That is what WhatsApp launched this time.

WhatsApp has finally come up with a new feature to make private chat more secure. The company has announced that from now on, end-to-end encryption will also be used in WhatsApp chat backup. Experts believe that this feature will strengthen the security of WhatsApp. WhatsApp chat backups saved on Google Drive and iCloud will now be protected by end-to-end encryption.

What are the new security features of WhatsApp?

All WhatsApp chats are protected by end-to-end encryption. As a result, no third party can read any end-to-end encryption WhatsApp messages except the sender and recipient of the chat. However, backups that customers save to regular chats in Google Drive or iCloud have not been backed up so far. As a result, if you could somehow manipulate that backup, all your chat information would be passed on to someone else. WhatsApp is also protecting chat backups through end-to-end encryption.

How to access encrypted WhatsApp chat backup?

According to WhatsApp, when the account owner needs to access the chat backup, the password or encryption key can be accessed. When retrieving a chat using a password, the HSM based backup key will be decrypted with the key from the vault.

What is HSM Key? How to keep the chat secure?

HSM Key will be used for password verification when retrieving WhatsApp chat. When a customer tries to secure WhatsApp chats with a password, this key will be stored in a backup key vault. This key will be stored in the Hardware Security Module (HSM) component. When the account owner needs to access the chat backup, the HSM backup key can be restored using the password.
