PSA: Have an #iPhone?

Do you think because of who you / what you do, someone may try to hack you?

Try enabling #LockdownMode.

For the first time, we found evidence that it does frustrate *certain* hacking attempts. 🧵1/ Image
2/ Here's the research I'm talking about👇

Basically, we @citizenlab found some sophisticated #Pegasus #spyware hacking attempts against human rights groups were getting stopped by #LockdownMode.

3/ When #LockdownMode first came out last year a lot of people were pointing out: hey, this mode degrades some features!

(#Apple is also up front about this)

So there was this question: are the trade-offs worth it?

Well, we finally have some evidence of it doing its job.

NEW INVESTIGATION: recent Mexican #Pegasus spyware abuses led us to evidence of a trio of zero-click exploits used by #NSO.

Targets? HomeKit & FindMy.

Remarkably, #Apple's #iOS #LockdownMode blocked one of them.

2/ First, the new victims: Mexican lawyers representing families of victims of Military abuses

The timing of the targeting matches key developments in efforts to hold #Mexico's army responsible.

It's really bad.

We @citizenlab forensically confirmed the spyware infections. One infected device belongs...ImageImage
3/ We found evidence of 3 #zeroclick #0day chains used by NSO's #Pegasus #spyware in 2022.

First: #PWNYOURHOME: worked against #homekit even if you didn't set up a home.

Apple's changes in iOS 16.3.1 that address.

#LockdownMode also kneecaps it. ImageImageImageImage

NEW: @Apple's #LockdownMode is radical reduction of the threat surface of an iPhone.

Cannot overstate how big a change this is for Apple.

So important that people at higher digital risk have the option to harden their phones.

Some thoughts 1/

2/ When you notify users that they've been targeted with sophisticated threats, they inevitably ask:

'How can I make my phone safer?'

We haven't had many great, honest answers that really make an impact.

Hardening a consumer handset is really out of reach.
3/There's a common mental barrier among big platforms & OS developers around mainstreaming high-security features.

A lot of inevitable considerations, like:

- Worse user experience (esp. vs. the competition!)
- Breaking features
- More customer support resources required, etc.
