Why is Tim Cook so angry at the government?

A federal magistrate-judge ruled Tuesday that Apple must help the FBI break into the phone of one of the San Bernardino shooters. The FBI was unable to figure out the shooter’s passcode, which is the only way to get inside his iPhone.

Here’s the problem: Apple doesn’t hold the keys to the shooter’s iPhone. The only way to break through an iPhone’s encryption lock is with a passcode, which isn’t stored on Apple’s servers.

The FBI could try to guess the shooter’s passcode, but if investigators guessed wrong 10 times, the shooter’s iPhone would permanently erase all of the content stored inside.

So the judge said Apple had to provide “reasonable technical assistance” to help it unlock the phone, including developing a software tool that would let investigators guess a passcode as many times as it needed to in order to break into the phone.

In a public letter opposing the FBI’s demands, Tim Cook didn’t mince words.

“The government is asking Apple to hack our own users and undermine decades of security advancements that protect our customers,” Cook said. “The same engineers who built strong encryption into the iPhone to protect our users would, ironically, be ordered to weaken those protections and make our users less safe.”

Cook said that to comply with the ruling, Apple will have to rewrite its iOS operating system. But once Apple gives special access to one person or group, it will have to give access to anyone.

Apple called the FBI’s demands a “backdoor,” which is a nasty term in the cybersecurity world.

If you leave a key under the mat — no matter how well hidden — it gives bad guys a potentially easy way in. Similarly, if the FBI can use a backdoor into your iPhone, hackers could too.

It might not sound like a big deal to be able to guess an iPhone passcode as many times as you’d like. There are 10,000 possible four-digit PINs.

But hackers have access to incredibly powerful computer networks called botnets, which would allow them to guess nine passwords per second, according to Dino Dai Zovi, an independent security consultant and notorious Apple hacker.

If Apple allowed that kind of “brute force” attack on an iPhone, it would take hackers 18 minutes at most to guess an iPhone’s password.

The debate over iPhone encryption started in September 2014, when Apple released iOS 8. That was the first operating system to encrypt iPhones by default, giving customers the only means of decrypting their phones. That means the only way for police to retrieve a suspect’s photos, messages, email, contacts, call history, iTunes content, notes and reminders is with a passcode.

The FBI has been up in arms about Apple’s encryption tactics, arguing that it will impede its investigations. It has been pleading with Congress to pass a law requiring Apple to build backdoors into its system. The FBI’s demands have met stiff resistance, and the Obama administration said it would no longer pursue a legal strategy to combat Apple’s encryption.

But the judge’s order could shift the tide against Apple.

“While we believe the FBI’s intentions are good, it would be wrong for the government to force us to build a backdoor into our products,” Cook said. “And ultimately, we fear that this demand would undermine the very freedoms and liberty our government is meant to protect.”

A Message to Our Customers

The United States government has demanded that Apple take an unprecedented step which threatens the security of our customers. We oppose this order, which has implications far beyond the legal case at hand. 

This moment calls for public discussion, and we want our customers and people around the country to understand what is at stake.

The Need for Encryption

Smartphones, led by iPhone, have become an essential part of our lives. People use them to store an incredible amount of personal information, from our private conversations to our photos, our music, our notes, our calendars and contacts, our financial information and health data, even where we have been and where we are going.

All that information needs to be protected from hackers and criminals who want to access it, steal it, and use it without our knowledge or permission. Customers expect Apple and other technology companies to do everything in our power to protect their personal information, and at Apple we are deeply committed to safeguarding their data.

Compromising the security of our personal information can ultimately put our personal safety at risk. That is why encryption has become so important to all of us.

For many years, we have used encryption to protect our customers’ personal data because we believe it’s the only way to keep their information safe. We have even put that data out of our own reach, because we believe the contents of your iPhone are none of our business.

The San Bernardino Case

We were shocked and outraged by the deadly act of terrorism in San Bernardino last December. We mourn the loss of life and want justice for all those whose lives were affected. The FBI asked us for help in the days following the attack, and we have worked hard to support the government’s efforts to solve this horrible crime. We have no sympathy for terrorists.

When the FBI has requested data that’s in our possession, we have provided it. Apple complies with valid subpoenas and search warrants, as we have in the San Bernardino case. We have also made Apple engineers available to advise the FBI, and we’ve offered our best ideas on a number of investigative options at their disposal.

We have great respect for the professionals at the FBI, and we believe their intentions are good. Up to this point, we have done everything that is both within our power and within the law to help them. But now the U.S. government has asked us for something we simply do not have, and something we consider too dangerous to create. They have asked us to build a backdoor to the iPhone.

Specifically, the FBI wants us to make a new version of the iPhone operating system, circumventing several important security features, and install it on an iPhone recovered during the investigation. In the wrong hands, this software — which does not exist today — would have the potential to unlock any iPhone in someone’s physical possession.

The FBI may use different words to describe this tool, but make no mistake: Building a version of iOS that bypasses security in this way would undeniably create a backdoor. And while the government may argue that its use would be limited to this case, there is no way to guarantee such control.

The Threat to Data Security

Some would argue that building a backdoor for just one iPhone is a simple, clean-cut solution. But it ignores both the basics of digital security and the significance of what the government is demanding in this case.

In today’s digital world, the “key” to an encrypted system is a piece of information that unlocks the data, and it is only as secure as the protections around it. Once the information is known, or a way to bypass the code is revealed, the encryption can be defeated by anyone with that knowledge.

The government suggests this tool could only be used once, on one phone. But that’s simply not true. Once created, the technique could be used over and over again, on any number of devices. In the physical world, it would be the equivalent of a master key, capable of opening hundreds of millions of locks — from restaurants and banks to stores and homes. No reasonable person would find that acceptable.

The government is asking Apple to hack our own users and undermine decades of security advancements that protect our customers — including tens of millions of American citizens — from sophisticated hackers and cybercriminals. The same engineers who built strong encryption into the iPhone to protect our users would, ironically, be ordered to weaken those protections and make our users less safe.

We can find no precedent for an American company being forced to expose its customers to a greater risk of attack. For years, cryptologists and national security experts have been warning against weakening encryption. Doing so would hurt only the well-meaning and law-abiding citizens who rely on companies like Apple to protect their data. Criminals and bad actors will still encrypt, using tools that are readily available to them.

A Dangerous Precedent

Rather than asking for legislative action through Congress, the FBI is proposing an unprecedented use of the All Writs Act of 1789 to justify an expansion of its authority.

The government would have us remove security features and add new capabilities to the operating system, 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.

The implications of the government’s demands are chilling. If the government can use the All Writs Act to make it easier to unlock your iPhone, it would have the power to reach into anyone’s device to capture their data. The government could extend this breach of privacy and demand that Apple build surveillance software to intercept your messages, access your health records or financial data, track your location, or even access your phone’s microphone or camera without your knowledge.

Opposing this order is not something we take lightly. We feel we must speak up in the face of what we see as an overreach by the U.S. government.

We are challenging the FBI’s demands with the deepest respect for American democracy and a love of our country. We believe it would be in the best interest of everyone to step back and consider the implications.

While we believe the FBI’s intentions are good, it would be wrong for the government to force us to build a backdoor into our products. And ultimately, we fear that this demand would undermine the very freedoms and liberty our government is meant to protect.
