Lockdown Mode

“the only issues so far are that the image carousel in the Amazon app no longer works”

“other than occasionally disabling it in Safari for websites it seems to work flawlessly for me”

“You basically lose up to 95% of performance in anything remotely resembling a JS heavy web app.”

“From what I can see in Apple docs, aside from web limitations it sounds great”

“lockdown mode is so restrictive that it doesn't really make sense for most users”

“I wish the features of Lockdown Mode were able to be enabled individually instead of a single all or none option.”

“If you enable lockdown mode on your iPhone and Mac, WASM is disabled through Safari.”

“it's prudent for everyone to turn off your phone or put it into Lockdown mode”

“Not that inconvenient but I didn't mind the slight no JIT slowdown.”

“Apple even has an answer for this as well with Lockdown mode which renders all of those previous exploits impossible.”

“That should be the default behavior, not a special lock down option that also disables other features.”

“there have been numerous exposed, active iOS exploitation campaigns of which none have worked against Lockdown mode”

“Except for disabled Javascript compilation possibly slowing down web sites, not getting some attachments in messages”

“which is essentially cope mechanism and Apple way of saying "we care about security, trust us bro"”

“It does nearly nothing to protect against non-browser/non-messaging attack vectors”

“Lockdown Mode bundles everything together and has very inconvenient changes many people won't accept.”

“if you are the kind of person these exploits are likely to target, you should have it on”

“Apple has already largely crushed hacking with memory tagging on the iPhone 17 and lockdown mode.”

“They should probably add these use case and copy in there so that the vulnerable enable it.”

“I find Lockdown Mode challenging, because you basically have to use it on every device you own in the Apple ecosystem to have it enabled.”

“So far, the impact has been negligible, though some apps and websites just don't work.”

“It's good to see Apple's Lockdown mode having such success by simply disabling message attachments.”

“Which is infinitely better than the cases we know about without the feature enabled.”

“We are not aware of any successful mercenary spyware attacks against a Lockdown Mode-enabled Apple device.”

“Lockdown Mode is supposedly a major upgrade given all the underlying processes it blocks / slows.”

“Lockdown mode is specifically engineered to protect against Cellebrite / Pegasus-level threats.”

“if you use iPhones and have reason to be really paranoid, consider using lockdown mode”

“Lockdown mode doesn’t require everyone else to lose large amounts of usable space on their own devices”

“When I turned on lockdown mode on my iPhone, there were a few notifications where the random spam calls I get were attempting a FaceTime exploit.”

“the other protections outside of web browsing seem to make it worth enabling lockdown mode”

“It is for journalists to not reveal their sources, whom might be at risk of severe consequences including death.”

“Just feels like the government is working with Apple here to help move some phones.”

“requires enabling a mode that is much broader, and sounds like it has a noticeable impact on device functionality.”

“having Lockdown Mode enabled actually protected her sources and work product”

“probably the most hardcore security modality that's ever shipped in mass produced consumer hardware”

“The things that Lockdown Mode disables actually massively reduce attack surface at the expense of user experience.”

“Claiming reduced attack surface without showing which exploit classes are actually eliminated is faith, not security.”

“Lockdown mode works by reducing the surface area of possible exploits.”

“It's basically an admission the model failed, with features turned off so users feel like they're doing something about it.”

“iOS in lockdown mode has multiple features disabled (or crippled, depending on how you look at it)”
