Users are prompted to update their WhatsApp smartphone applications immediately due to a security error that allows hackers to take over the phone just by calling it, regardless of whether you answer.
A vulnerability in the popular Facebook-owned messaging service has been discovered which allowed hackers to install spyware through an infected WhatsApp voice call.
The spyware can step through conversations, texts and other data, activate the phone's camera and microphone, and perform other malicious activities.

All brands of phones with WhatsApp or WhatsApp Business installed are affected, including Apple's iPhone (iOS), Android phones, Windows phones and Tizen devices, according to Facebook. WhatsApp is used by 1.5 billion people globally.
Who's behind the attack?
According to the Financial Times, Israeli chat business developed the NSO Group spyware. The users didn't even have to accept the call, and it was often hidden from logs, wrote the paper.
Has it affected me?
The number of people who are spied on is not yet known. A few targets, including a British-based human rights lawyer and an Amnesty International researcher, have been identified.
If you haven't received any WhatsApp voice calls or dropped calls from unknown parties, you probably haven't been targeted. However, if you happen to be a lawyer or work in sensitive industries and use WhatsApp, even for personal correspondence, you should be particularly vigilant.
What do I have to do to protect myself?
Facebook implemented a server-side change to protect users and elaborate updates for the various smart types of WhatsApp versions on Monday.

What about my phone?
Keeping your apps up to date is essential to protecting yourself
You should always install the latest version iOS or Android and should think twice before using a phone that is no longer supported by software updates.
Most iPhones receive over five years of software support. Android devices rely on the manufacturer, with Google's Pixel smartphones as the gold standard, and receive at least three years of monthly security updates and Android version updates.
Why is software support so important?
Security issues are being discovered all the time and each is added to a hacker's armory, and they are often combined in creative ways of acquiring devices and stealing data.
Although most security holes are solved by software vendors, you are only protected if you actually receive the software solution. For most users, there is nothing you can do to solve the problem yourself, which means you are completely dependent on the software support you receive from the developer or device manufacturer.
The older your software, the more vulnerable it affects and the greater your risk from cyber criminals.
