This is despite the company encrypting messages since 2014, but only recently in light of the spyware issue, rolled E2E encryption across its services. In April this year, the company released a newer version of the app that ensures all voice and video calls, messages and files sent are completely secure and end-to-end encrypted. When you ask how secure is WhatsApp voice calls, this example doesn’t provide much confidence. WhatsApp was unable to confirm just how many users were affected by this spyware.
This was achieved by using the voice call function, where attackers simply called targets and the malicious code could be transmitted even without a user answering the call. In May 2019, a vulnerability was discovered that allowed spyware to be added to both IOS and Android devices. However, soaring usage and popularity attracts cyber criminals looking to take advantage. In 2018, WhatsApp Business was launched offering SMEs a way to connect with their customers in real-time, attracting 3 million users. Not content with being the world’s most popular messaging app with 1.5 billion users in 180 countries, WhatsApp added mobile VoIP in March 2015, a year after being acquired by Facebook in the company’s largest acquisition to date. It seems the goal for WhatsApp is to become an all-round platform, but how secure are data protection and privacy on WhatsApp voice call in its current form? WhatsApp Voice Calls Under the Spotlight Many of the popular communication platforms provide VoIP as well as messaging and video calls, such as WhatsApp and Messenger, with the former also announcing plans to enter the video conferencing market to challenge Zoom and Microsoft Teams by upgrading their desktop app in the coming months. Integrated Voice Over Internet Protocol (VoIP) is expected to reach 204.8 billion corporate consumers in 2020, becoming an essential business tool. Even customers agree on the whole with 59% preferring to call because they want a quick answer according to Google’s ‘Click to Call’ research. But whilst video calling is becoming the main focus for many, voice calls are still by far the most popular way to communicate especially at work.
Thanks, in no small part, to a global pandemic that has seen social distancing and remote working become commonplace, video calls suddenly became extremely popular as an alternative to the humble voice call. Video calls and conferencing is having its moment, with more users than ever using this form of communication to stay in touch with friends, family and for business.
