With the increase in technological advancement, the rate of a cyber attack has witnessed a tremendous rise, causing privacy concern for users. Lately, WhatsApp, a service owned by Facebook, has reported about its vulnerability that allowed cyber hackers to install surveillance spyware on the users Smartphone. The hackers have achieved this attack by merely making a call on a targeted phone with the help of WhatsApp voice call. Adhering to this attack has awakened WhatsApp to notify its users to update the app using the app stores as so as possible. This notice aims to protect the phone against the vulnerability spyware, which makes use of the WhatsApp voice calling features.
It shows that the Israeli technological company NSO Group, famous for producing highly developed and sophisticated mobile spyware, has developed the questioned spyware and sold it to the attackers. The hackers used Pegasus Spyware to launch an attack on Smartphone users using the WhatsApp voice call as a disguised tool. Based on the claims of WhatsApp, some of the app versions affected by the spyware include WhatsApp for iSO before v2.19.51, WhatsApp for Android before v2.19.134, and WhatsApp for Windows phone before v2.18.348, among many others. However, the NSO Group has claimed that its spyware only deals against a legal targeted group and that the recent Whatsapp vulnerability has no connection with its organization. Nevertheless, Whatsapp believes that the incursion is linked to NSO Group as it has all the official marks of the company that works with legal authority concerning technological operating system like the mobile phone. Further, NSO Group spyware has allowed hackers to gain entry over the victim Smartphone leaving the privacy of the users at the hands of the hackers. The spyware can also access to other multimedia features emails, location, contact, etc.
Another claim made about WhatsApp vulnerability reveals that the lack of safeguard in WhatsApp voice call has allowed the hackers to perform any incursion on the targeted Smartphones. The Whatsapp hacking app can easily install the spyware on the targeted phone by using the Whatsapp Common Vulnerabilities and Exposures (CVE) 2019-3568. Further, the hackers could transfer the spyware to the targeted Smartphone users by using the WhatsApp voice call features as the channel, and thus infects the phone whether or not the Smartphone users receive the attack call. This attack allows hackers to steal personal data from the users of Smartphone. Besides, the spyware erases all the formalities carried during the attack, thereby leaving the victims clueless about the incursion.
It is difficult for WhatsApp to provide a correct number of users affected by the NSO Group spyware. NSO Group has claimed to have infected many WhatsApp Smartphone users by merely making a voice call. The correct number of users is uncertain following cyber incursion. However, the number of affected users counts to very few and not all WhatsApp users.
