Backdoor dans l’iPhone, Apple admet que c’est possible mais refuse, explication

Apple réaffirme sa position sur la nécessiter de garantir la sécurité des données de ses iPhone. La firme tente d’unir les forces pour ne pas répondre aux demandes du FBI.


Le PDG d’Apple, Tim Cook, vient une nouvelle fois de prendre la parole face à une décision demandant à Apple d’aider le FBI à percer la sécurité de l’iPhone d’un des auteurs de la fusillade de San Bernardino. Vous pouvez relire notre actualité à ce sujet – Backdoor dans l’iPhone, Google et Microsoft aux côtés d’Apple, pas d’usage de porte dérobée  – .

iPhone, le FBI veut tout contrôler ?

Tim Cook a pris la décision de ne pas répondre favorablement à cette demande en raison des risques de sécurité et des violations de la vie privée que cela pourrait impliquer.

Dans une récente intervention il explique

« Le gouvernement voudrait que nous écrivions un tout nouveau système d’exploitation pour leur utilisation »

Selon plusieurs média américains ceci sous-entend que le FBI ne veut pas nécessairement un moyen d’obtenir un accès au contenu stocké sur un smartphone iPhone, mais souhaite « être en mesure de le contrôler »

Tim Cook ajoute

« Il demande à Apple de supprimer des fonctionnalités de sécurité et d’ajouter une nouvelle capacité au système d’exploitation pour attaquer le cryptage de l’iPhone, permettant l’usage d’un code d’accès à saisir électroniquement »

A ses yeux

“Cela serait une erreur d’affaiblir intentionnellement nos produits avec une porte dérobée ordonnée par le gouvernement. Si nous perdons le contrôle de nos données, nous mettons notre intimité et notre sécurité en danger […] Le monde numérique est très différent du monde physique. Dans le monde physique, vous pouvez détruire quelque chose pour le faire disparaitre. Mais dans le monde numérique, la technique, une fois créé, peut être utilisée encore et encore, sur un certain nombre de dispositifs »

Backdoor dans l’iPhone, c’est possible mais dangereux.

Tim Cook reconnait qu’il est techniquement possible de répondre favorablement aux demandes du FBI. Apple peut développer un tel logiciel pour « percer » l’iPhone, mais la firme ne le souhaite pas en raison des menaces de sécurité que cela pourrait entrainer une fois sa finalisation terminée.

L’homme ajoute

“Oui, il est certainement possible de créer un tout système d’exploitation afin de « saper » nos fonctions de sécurité […] Mais il nous pensons que c’est trop dangereux de le faire. La seule façon de garantir qu’un tel outil puisse pas tomber entre de mauvaises mains est de ne jamais le créer »

Enfin le PDG de la société a commenté les récentes accusations du FBI visant à démontrer qu’Apple refuse d’apporter son aide afin de profiter d’un « coup marketing » pour augmenter ses ventes.

Tim Cook explique qu’Apple est ouvert à de nouvelles discussions et prêt à apporter son aide cependant le gouvernement “devrait retirer ses demandes » et mettre en place une communion capable d’analyser toutes les implications de telles demandes.

Qu’en pensez-vous ? Y-a-t-il vraiment un danger ? Est-ce une stratégie marketing d’Apple ou d’une véritable préoccupation pour l’avenir de la protection des données personnelles ?

Tim Cook’s letter to employees

Subject: Thank you for your support


Last week we asked our customers and people across the United States to join a public dialogue about important issues facing our country. In the week since that letter, I’ve been grateful for the thought and discussion we’ve heard and read, as well as the outpouring of support we’ve received from across America.

As individuals and as a company, we have no tolerance or sympathy for terrorists. When they commit unspeakable acts like the tragic attacks in San Bernardino, we work to help the authorities pursue justice for the victims. And that’s exactly what we did.

This case is about much more than a single phone or a single investigation, so when we received the government’s order we knew we had to speak out. At stake is the data security of hundreds of millions of law-abiding people, and setting a dangerous precedent that threatens everyone’s civil liberties.

As you know, we use encryption to protect our customers — whose data is under siege. We work hard to improve security with every software release because the threats are becoming more frequent and more sophisticated all the time.

Some advocates of the government’s order want us to roll back data protections to iOS 7, which we released in September 2013. Starting with iOS 8, we began encrypting data in a way that not even the iPhone itself can read without the user’s passcode, so if it is lost or stolen, our personal data, conversations, financial and health information are far more secure. We all know that turning back the clock on that progress would be a terrible idea.

Our fellow citizens know it, too. Over the past week I’ve received messages from thousands of people in all 50 states, and the overwhelming majority are writing to voice their strong support. One email was from a 13-year-old app developer who thanked us for standing up for “all future generations.” And a 30-year Army veteran told me, “Like my freedom, I will always consider my privacy as a treasure.”

I’ve also heard from many of you and I am especially grateful for your support.

Many people still have questions about the case and we want to make sure they understand the facts. So today we are posting answers on apple.com/customer-letter/answers/ to provide more information on this issue. I encourage you to read them.

Apple is a uniquely American company. It does not feel right to be on the opposite side of the government in a case centering on the freedoms and liberties that government is meant to protect.

Our country has always been strongest when we come together. We feel the best way forward would be for the government to withdraw its demands under the All Writs Act and, as some in Congress have proposed, form a commission or other panel of experts on intelligence, technology and civil liberties to discuss the implications for law enforcement, national security, privacy and personal freedoms. Apple would gladly participate in such an effort.

People trust Apple to keep their data safe, and that data is an increasingly important part of everyone’s lives. You do an incredible job protecting them with the features we design into our products. Thank you.


Q&A session posted on Apple webpage

Why is Apple objecting to the government’s order?

The government asked a court to order Apple to create a unique version of iOS that would bypass security protections on the iPhone Lock screen. It would also add a completely new capability so that passcode tries could be entered electronically.

This has two important and dangerous implications:

First, the government would have us write an entirely new operating system for their use. They are asking Apple to remove security features and add a new ability to the operating system to attack iPhone encryption, allowing a passcode to be input electronically. This would make it easier to unlock an iPhone by “brute force,” trying thousands or millions of combinations with the speed of a modern computer.

We built strong security into the iPhone because people carry so much personal information on our phones today, and there are new data breaches every week affecting individuals, companies and governments. The passcode lock and requirement for manual entry of the passcode are at the heart of the safeguards we have built in to iOS. It would be wrong to intentionally weaken our products with a government-ordered backdoor. If we lose control of our data, we put both our privacy and our safety at risk.

Second, the order would set a legal precedent that would expand the powers of the government and we simply don’t know where that would lead us. Should the government be allowed to order us to create other capabilities for surveillance purposes, such as recording conversations or location tracking? This would set a very dangerous precedent.

Is it technically possible to do what the government has ordered?

Yes, it is certainly possible to create an entirely new operating system to undermine our security features as the government wants. But it’s something we believe is too dangerous to do. The only way to guarantee that such a powerful tool isn’t abused and doesn’t fall into the wrong hands is to never create it.

Could Apple build this operating system just once, for this iPhone, and never use it again?

The digital world is very different from the physical world. In the physical world you can destroy something and it’s gone. But in the digital world, the technique, once created, could be used over and over again, on any number of devices.

Law enforcement agents around the country have already said they have hundreds of iPhones they want Apple to unlock if the FBI wins this case. In the physical world, it would be the equivalent of a master key, capable of opening hundreds of millions of locks. Of course, Apple would do our best to protect that key, but in a world where all of our data is under constant threat, it would be relentlessly attacked by hackers and cybercriminals. As recent attacks on the IRS systems and countless other data breaches have shown, no one is immune to cyberattacks.

Again, we strongly believe the only way to guarantee that such a powerful tool isn’t abused and doesn’t fall into the wrong hands is to never create it.

Has Apple unlocked iPhones for law enforcement in the past?


We regularly receive law enforcement requests for information about our customers and their Apple devices. In fact, we have a dedicated team that responds to these requests 24/7. We also provide guidelines on our website for law enforcement agencies so they know exactly what we are able to access and what legal authority we need to see before we can help them.

For devices running the iPhone operating systems prior to iOS 8 and under a lawful court order, we have extracted data from an iPhone.

We’ve built progressively stronger protections into our products with each new software release, including passcode-based data encryption, because cyberattacks have only become more frequent and more sophisticated. As a result of these stronger protections that require data encryption, we are no longer able to use the data extraction process on an iPhone running iOS 8 or later.

Hackers and cybercriminals are always looking for new ways to defeat our security, which is why we keep making it stronger.

The government says your objection appears to be based on concern for your business model and marketing strategy. Is that true?

Absolutely not. Nothing could be further from the truth. This is and always has been about our customers. We feel strongly that if we were to do what the government has asked of us — to create a backdoor to our products — not only is it unlawful, but it puts the vast majority of good and law abiding citizens, who rely on iPhone to protect their most personal and important data, at risk.

Is there any other way you can help the FBI?

We have done everything that’s both within our power and within the law to help in this case. As we’ve said, we have no sympathy for terrorists.

We provided all the information about the phone that we possessed. We also proactively offered advice on obtaining additional information. Even since the government’s order was issued, we are providing further suggestions after learning new information from the Justice Department’s filings.

One of the strongest suggestions we offered was that they pair the phone to a previously joined network, which would allow them to back up the phone and get the data they are now asking for. Unfortunately, we learned that while the attacker’s iPhone was in FBI custody the Apple ID password associated with the phone was changed. Changing this password meant the phone could no longer access iCloud services.

As the government has confirmed, we’ve handed over all the data we have, including a backup of the iPhone in question. But now they have asked us for information we simply do not have.

What should happen from here?

Our country has always been strongest when we come together. We feel the best way forward would be for the government to withdraw its demands under the All Writs Act and, as some in Congress have proposed, form a commission or other panel of experts on intelligence, technology, and civil liberties to discuss the implications for law enforcement, national security, privacy, and personal freedoms. Apple would gladly participate in such an effort.
