WhatsApp vulnerability allowed government-grade spyware to be installed on phones
TechCrunch reports that the vulnerability discovered by WhatsApp just a few weeks ago, would allow a caller to install a spyware on the device being called, regardless of whether or not the could was answered.
The spyware installed was made by Israel-based NSO Group Pegasus, and is usually licensed to governments that want to hack targets of investigations and gain access to multiple aspects of their devices.
It's unclear how many Android and iOS devices were affected by the vulnerability, but as you can imagine, anyone with access to the spyware could hack any WhatsApp user. On the bright side, WhatsApp said that it took less than 10 days after it discovered the security issue to patch it. The company also belives that only a relatively small number of users were targeted by the attack.
If you have WhatsApp installed on your phone, installing the latest version of the app will render the attack inoperable, even if it was infected with the government-grade spyware.
