First and foremost, TibCERT recommends using Signal for truly secure communication as it not only provides end-to-end encryption but is open-source, which means that all of Signal’s code is made public, allowing us to verify how Signal is built. At the same time, Signal doesn’t store any personal data apart from your phone number, and it is “built to protect” based on the Privacy by Design Principle. Many WhatsApps users have transitioned to communication apps like Signal, Telegram, and others. But, we know there are also many reasons people continue to use WhatsApp for ease of communicating with family and friends. And, if you’re using WhatsApp instead of Wechat for communication (in countries where WhatsApp is accessible) then half the battle is already won!
When it comes to secure communication, WhatsApp is an important step in the right direction. This is why we’re explaining what you really need to know about WhatsApp’s changes. Also, at the end of the post, we highlight important steps that can make your WhatsApp account even more secure – don’t forget to check these out!
WhatsApp also tweeted a clarification regarding the rumours about it removing its end-to-end encryption feature. A screenshot of the official WhatsApp tweet is shown below.
In conclusion: It’s encouraging to see the notifications pop up on my phone letting me know that many of my contacts have started using Signal. However, the reality is that many of us are still using WhatsApp and will probably continue to use WhatsApp. On top of end-to-end encryption (which is default in the app), there are few additional steps that one can take to enhance security on WhatsApp.
Step 1: Enable 2-step verification. This will make sure that even if someone gets access to your phone number, they are not able to register a fake WhatsApp account using your phone number.
Step 2: Privacy Setting. You can make sure that only contacts can see “Last Seen”, “Profile Photo”, “Live Location” and to enable “Screen Lock” too.
Step 3: Turn off Chat Backup: You can turn off the setting that backs up your Chats (on Icloud on an iphone or Google Drive on an Android) because backing up chats removes end-to-end encryption when it is stored externally.
Step 4: Secure your photos: Change your settings so that your photos are not saved to your phone’s photo gallery/Camera Roll and other apps are unable to access it . This will ensure media files such as photo or video are also end-to-end encrypted.
