Citizen Lab found an actively exploited zero-click vulnerability being used to deliver NSO Group’s Pegasus mercenary spyware while checking the device of an individual employed by a Washington DC-based civil society organization with international offices. We refer to the exploit chain as BLASTPASS. The exploit chain was capable of compromising iPhones running the latest version of iOS (16.6) without any interaction from the victim.
How do you block MMS from unknown senders on iOS?
Settings > Messages > SMS/MMS > MMS Messaging (uncheck)
And/Or
Message Filtering > Filter Unknown Senders (checked)
Those seem to be the likely options, but I’ve zero idea if those will work.
sorry, I was meaning to reply on the android comment to the post I actually commented on.
