Nowadays there are so many messaging apps people use such as WhatsApp, Telegram and Signal. We exchange text, pictures, videos and many other things. However, no messaging app is 100% safe.
Recently, a research team Technical University of Darmstadt and the University of Würzburg showed that popular messenger apps can be exploited to expose personal data and contact information through the phone book. The researchers used hacking techniques to show that professional hackers can collect large sensitive without any restrictions.
Even in the past also, there were many privacy concerns. Although the mobile app companies have updated their security for safe communications. For instance, they have started using end-to-end encryption. This means that only the sender and receiver of the message can read it. Otherwise the message will be scrambled so that it can’t be read by a third party. It was after Edward Snowden leaked classified documents pertaining to a US surveillance program that people started taking online privacy more seriously.
Some messaging apps have the encryption program as its default security while others don’t. The best thing is for you to check in the settings of the app if the encryption feature is off or not.
Despite the use of the encryption feature, some apps still collect data about you. This is known as metadata and it can include who you talk to, frequency of communication, your IP address, contact list and much more. To avoid collection of such data, you can install a (Virtual Private Network) VPN app on your mobile device. The VPN app helps to maintain a private environment on the phone, whether you are at home or using a public WiFi. One of the best VPN apps is ExpressVPN.
Another thing we should be aware of the history of the company that made the app. Although there can still be errors but a company has to be take responsibility to protect the privacy of it’s users. Such a company should make sure to inform it’s users in case of any breach of security.
