Probably not. Back when the WhatsApp Pegasus vulnerability happened, there was a vector on iOS, but it was iMessages.
I don’t know any first hand details, but my suspicion is that the way WhatsApp on Android worked was via Facebook system apps bundled with the phone by the manufacturer. Back in the day, Facebook itself used to be a system app on some phones (making it difficult to remove), but gradually they moved away from that to having the Facebook or WhatsApp apps be the same as the one on Google Play, but there would be a separate system app that would be much harder to remove. I suspect this system app used various exploits for further data mining by Facebook (perhaps even gaining microphone access so they can present ads based on what you say?) and that the Pegasus hack got into WhatsApp, then simply called the system app to use its established exploits. One other thing that maybe points to this: the Pegasus hack would only sometimes be effective on Android phones, and researchers couldn’t pin down why. To me, that suggests some other app or configuration variation.
WhatsApp on iOS shouldn’t have this vector, as Apple control both software and hardware on their phones, hence why the strategy was to go for Apple apps directly (as they had the direct access to system level permissions, like I’m alleging Facebook sometimes had on Android).
Like I say, the exact workings of the hack are my own assumptions, and I understand that the WhatsApp Pegasus entry vector has been patched, but ultimately I don’t think Facebook/Meta or any of their apps are trustworthy and encourage people to remove them from their devices.
It’s only just about functional and clunky as fuck. But if you want to get rid of WhatsApp from your device but still need to talk to someone in it then it’s a good shout.
