How Safe Is WhatsApp?
Though WhatsApp has been hacked and criticized many times in the past, it fixed its bugs/vulnerabilities and corrects its manners to protect user’s privacy and security. Besides the actions WhatsApp takes mentioned above, it has also done below aspects.
In November 2019, WhatsApp released a new privacy feature that allows users to determine who adds them to the group chat.
Since February 1st, 2020, for security purposes, WhatsApp stops support for smartphones running legacy OSes including iPhone iOS 8 or older and Android 2.3.7 or older that are no longer updated by their providers.
WhatsApp Security Features
The following functions are provided by WhatsApp to protect your privacy and protect you from cyberattacks.
- Privacy Settings: You can control by setting your profile photo, last seen, and about to be seen by everyone, contacts only, or no one.
- Two-Step Verification: Create a six-digit pin to enable extra security for your WhatsApp account.
- Block Unwanted Users: Stop some from contacting you directly from a chat.
- Clear Chat Messages: Delete all messages inside an individual or group chat, or all chats at once.
- Delete and Report Spam: Report spam from inside the program.
- Request Account Info: Get a report of your WhatsApp account information and settings.
- Turn off Read Receipts: Choose whether someone can see if you have read their message or not.
- Leave a Group: You can exit a group at any time.
Though the privacy protection services provided by WhatsApp is widely accepted and praised by users all over the world. Yet, there are still some people who hold different ideas.
For example, in March 2017, the British Home Secretary Amber Rudd said that the encryption feature of messaging apps like WhatsApp is unacceptable for news reported that Khalid Masood used WhatsApp for several minutes before perpetrating the 2017 Westminster attack. Rudd called for that the police and intelligence agencies to be given access to WhatsApp and other encrypted messaging services to prevent future terrorism.
However, personally, I doubt the proposal by Rudd. Though his intention is good, he can’t deny that malicious people who work in police offices and intelligence agencies will take this privilege to hack others’ privacy.
