Google pioneered the out-of-process architecture that Safari now uses, developed the Safe Browsing program that Safari also uses, drove the adoption of HTTPS, put pressure on misbehaving certificate authorities and shepherded certificate pinning and then Certificate Transparency, and found many vulnerabilities in WebKit through security research that Apple was not itself doing. Moreover, on the desktop, Chrome and Firefox both have automatic update channels that allow them to push out security fixes much more rapidly than Apple's heavy OS updates. All this to say, I'm skeptical of the suggestion that a Blink-powered Chrome for iOS would not "protect users as adequately as our WebKit protections.

Google pioneered the out-of-process architecture that Safari now uses, developed the Safe Browsing program that Safari also uses, drove the adoption of HTTPS, put pressure on misbehaving certificate authorities and shepherded certificate pinning and then Certificate Transparency, and found many vulnerabilities in WebKit through security research that Apple was not itself doing.

Moreover, on the desktop, Chrome and Firefox both have automatic update channels that allow them to push out security fixes much more rapidly than Apple's heavy OS updates.

All this to say, I'm skeptical of the suggestion that a Blink-powered Chrome for iOS would not "protect users as adequately as our WebKit protections. A third-party JavaScript engine would be much slower without this ability, but granting the capability to third-party engines would jeopardize the security architecture of iOS.

Despegar on Nov 20, Apple is plainly saying that they are best positioned to protect iOS users privacy and security. One way they do that is by not allowing any app to use anything other than WebKit. If there's a flaw in some alternative browser that iOS app developers now have a dependency on, Apple would be unable to do anything about it other than wait for that other browser vendor to ship an update. It's also privacy.

And Safari's track record on privacy technologies is longer and better than everyone. Furthermore, Apple sells integrated products. They don't sell operating systems, browsers, app stores, and NFC chips. They sell a finished good that incorporates all of those things and more. They take end to end responsibility for their products and it would be frankly uncharacteristic of Apple to have any other position than extreme self-reliance.

They sell a finished good Microsoft didn't sell IE either, it too was once part of a package called Windows.

Shank on Nov 20, There's an important distinction though. Windows is a de facto monopoly in the sense that almost every PC built has Windows installed on it, but not all PCs built are by Microsoft. Apple has always maintained that the physical object is tied to its software and vice versa, on the other hand.

They have no interest in running on the vast majority of mobile devices android handsets control the majority of smartphone market share by a wide margin. The only exception to this is when Apple is selling services, in which case they let you run iTunes on Windows and Apple Music on Android. This is an irrelevant argument in a perspective of monopoly and its market definition.

Even Apple itself gives a list of competing web browsers in the iOS ecosystem to refute App Store monopoly arguments, but this also strongly suggests that iOS and Safari are separate products and browsers in iOS itself is a competing market.

The only possible argument is that iOS is not in a dominant position in the smartphone market thus Apple cannot exercise monopolistic powers. But people doesn't change their phone because of web browser engine since its prohibitively expensive for this purpose.

The result is that an Android phone doesn't work as an alternative for iPhone, thus iOS can be defined as a sole market for browser products in terms of monopoly of course. This could've been solved if Apple allowed installation of other OS in iPhone, but they've made their choice a long time ago. The key difference being that Microsoft was found to have market dominance and using that position anticompetitvely. Well, yes, that is the battlefield here: should the market in software, services, and media exist, or should consumers have to pick which vertical silo to use and then be unable to switch without prohibitive re-purchasing and setup costs?

Terretta on Nov 22, The iPhone is a PDA is a toaster. Splitting the software from the hardware is like splitting the coils from the chrome. The consumer just wants perfectly consistently browned toast, while not dying from electrical shock or setting her house on fire.

To characterize the consumer wants around an iPhone and its variable uses as akin to the near uniform customer expectation to have a toaster that doesn't burn their house down while doing its job is hard for me to accept. If a customer is really seeking "no hassle toast" when buying a toaster, what is the customer buying in an iPhone? No-hassle phone? If so, are we construing "giving the consumer the option of installing software on their own device" as a hassle?

With something like a phone, I believe users have come to expect the ability to install software of their choosing on the device, which is very different from expectations of software installation for something like a toaster.

I have a mid 90s uneducated great grandmother who grew up and still is in a rural village in a poor country able to contact all of her great grandchildren and video chat with them for the past 7 years. Exactly the same as every other OS including MacOS one interpretation is they are claiming the are incompetent at securing iOS but somehow competent at securing Safari. Those seem like opposing statements.

Either they are competent at both and so 3rd party browsers are fine or they are competent at neither and we need access to more competent browser teams. I would like to believe they are competent and that their excuses are untrue. Otherwise we should go back to the world of no Firefox or Chrome because that same argument would apply to MacOS and Windows. Mozilla Firefox anybody?

If Apple cares about privacy so much then why don't they allow ad blockers on safari? I mean, even the Brave browser on iOS is better then Safari at blocking trackers and advertisements. Firefox also tells me how many trackers they have blocked and also give me the option to completely opt out of any telemetry data collection. There is a content blocker API that has been available for a few years on both macOS and iOS, and there are third-party ad blockers that use it.

The design is more performant than holding each load up on a traditional browser extension's decision, and does not permit the content blocker to track your browsing history and then upload it somewhere. It also conveniently allows Apple to get away with not providing a more flexible browser extension API while supporting the most common use case. Apple has had a content blocking framework on iOS for years that not only works with Safari, but also works with embedded web views that use the SafariViewController.

They do. I am running Crystal right now on mobile Safari. I also have ad blockers on desktop Safari as well. Certainly I would say Apple is doing better on privacy than Google, but when it comes to the browser specifically, I don't think they're doing significantly better. Google, for instance, pioneered Incognito mode edit: nope, Safari beat them.

Chrome allowed you to configure DuckDuckGo as your default search engine pretty much from the beginning as long as you did it manually , whereas Safari took years to allow it. Safari has been slowly shutting out many forms of third-party extensions which are frequently for ad and tracker blocking. To be fair Apple has a design that reduces the amount of trust you need to put in an ad blocker to see your browsing behavior, but it is far more limited, and likely sees far lower adoption.

I do think Apple is prioritizing privacy-protecting features higher than Google is, so it would not surprise me to see Safari come ahead with features like Intelligent Tracking Prevention which conflict with Google's business interests.

I think there's an excellent case for Safari. It had private browsing in , before Chrome even existed. It was the first to block third party cookies by default, and today only Chrome still allows them. It added DDG as an option in , while Chrome added it only this year. There's a nuance here. Apple's list of search engines comes from a cryptographically signed file which only they can modify.

Chrome allowed you to manually configure DDG, but omitted it from the pre-configured list of search engines that included Bing and Yahoo!. Interestingly, the ability to add a new search engine has been removed from Safari with the deprecation of legacy extensions.

It's true that you couldn't add it as an option to the fixed list, but in practice there were extensions that enabled it. I agree that Chrome would protect users' security privacy is a different issue. But that's one browser, not an arbitrary browser. Could you allow Chrome without allowing other browsers with lesser pedigree? Keep in mind that several of Congress' questions are asking whether Apple provides privileged access to favored partners.

Sure, you could have security auditing standards required for apps with certain functionality, including browsers, and apply them in a neutral manner across vendors. That might structurally favor larger firms, but wouldn't favor partners. I read Apple's responses as "We want to protect the reputation of a brand of device which is marketed as user friendly, secure and private".

If they open up the device to allowing anyone to deploy buggy software on, there will be a greater incidence of headlines similar to "iPhones with XYZ browser can be hacked!!

Apple's own bugs deleted entire hard drives. From ? Not that that's an excuse, but few machines were affected by this. Even if not being purposefully malicious, third parties get sloppy. I'm fairly sure Apple's security spin comes exclusively from the fact that apps on the App Store cannot dynamically allocate executable memory.

I think you got that backwards. Is that not what I said? This also renders iOS devices useless for even basic browsing after the OS updates ends. Where as, a 7 year old Android device which hasn't received any OS updates can still use latest Firefox with regular updates. The risk should be up to the consumer to take imho. That worked so well for Android and Windows I mean, it did? Right now on Android or Windows, you have multiple different high-quality browsers you can pick from Chrome, Firefox, Opera, Brave, etc , and because they all have to compete with each other, they're continually improving the user experience.

In particular, Firefox and Brave have been able to add improved privacy protections by modifying the rendering engine, which isn't possible on iOS. How will the user know whether software is secure? Seems to be working for MacOS.

Only because hardly anyone bothers to write malware for the Mac. This is a outright lie by Apple. They know other entities are capable of browser security. How in the world can an opinion be a lie? They didn't objectively state that other entities aren't capable of it.

Hackers release new browser-based iOS 'jailbreak' based on PDF exploit

Icons and other pieces of applications are PDFs, the rendering system is tied closely to the data model used by PDFs, and any application that can print can also produce PDFs. Given this fondness for PDF, it makes sense that the Preview application Apple provides for examining the contents many different file types also supports PDF. Figure Preview's overall interface is much simpler than the Acrobat Reader's interface, though the options are friendly and clear. Preview also creates thumbnail images of pages, which is convenient for quick navigation. Also, Preview's File Export. Toggle navigation.

It is the operating system that powers many of the company's mobile devices, including the iPhone and iPod Touch ; the term also included the versions running on iPads until the name iPadOS was introduced with version 13 in It is the world's second-most widely installed mobile operating system, after Android. It is proprietary software, although some parts of it are open source under the Apple Public Source License and other licenses. Unveiled in for the first-generation iPhone , iOS has since been extended to support other Apple devices such as the iPod Touch September and the iPad January Major versions of iOS are released annually. The current stable version, iOS 14 , was released to the public on September 16, No devices were dropped, as all devices supported by iOS 13 are able to run iOS

To start the conversation again, simply ask a new question. This happened last year and people on this forum are telling me I'm crazy and all they did was criticize me. I only tried to shut off all my computers that were infected off Wifi. It was so infected that my apps i download are software developed and used in the apps i download from thr app store to mask the malware and adware. They show up such as the Icon and Facetime. What can I do to fix this since Apple can't really help. They are having their engineers look at it for the past 4 days and only had one call back.

Germany warns of Apple security problem

Now that the honeymoon stage with Mac OS X Leopard has passed, the nuances of its daily use are beginning to come to light. Kinks are getting worked out, companies are updating their Mac-compatible software and all kinds of new and useful features are being unearthed. In the past, Mac OS X has been derided for flawed security while at the same time being lauded as an unlikely target for hackers.

Several versions of Apple's iPhone, iPad, and iPod Touch have potentially serious security problems, a German government agency said in an official warning Wednesday. Opening a manipulated website or a PDF file could allow criminals to spy on passwords, planners, photos, text messages, e-mails and even listen in to phone conversations, the agency said in a statement. Although no attacks have been observed yet they were likely to appear soon, the German agency said. The application targeted in such an attack, Alberts noted, is not Adobe Systems Inc.

 Джабба, - спросил Фонтейн, - много они похитили. - Совсем мало, - сказал Джабба, посмотрев на монитор.  - Всего лишь какие-то обрывки, в полном виде -. Фонтейн медленно кивнул и улыбнулся одними уголками губ. Он искал глазами Сьюзан Флетчер, но она уже стояла прямо перед экраном, на котором крупным планом было видно лицо Дэвида Беккера. - Дэвид. - Привет, красавица.
