With laptops banned onboard aircraft, your data is no longer yours if you fly

New US regulations ban laptops on board some aircraft, requiring laptops to be in checked luggage. One of the first things you learn in information security is that if an adversary has had physical access to your computer, then it is not your computer anymore. This effectively means that the US three-letter agencies are taking themselves the right to compromise any computer from any traveler on these flights.

According to the United States Department of Homeland Security, which bills the ban as a “change to carry-on items” that affect “ten out of the more than 250 airports that serve the United States internationally”, there is a “security enhancement” because explosives can now be built into “consumer items”, and therefore laptops must now be banned from carry-on luggage and instead checked in.

When looking at this justification, the DHS notably fails to describe how it would be any safer flying with such alleged explosives in checked luggage rather than carry-on luggage onboard the same aircraft. In other words, the justification is utter nonsense, and so, there must be a different reason they issue this edict that they’re not writing about.
“The aviation security enhancements will include requiring that all personal electronic devices larger than a cell phone or smart phone be placed in checked baggage at 10 airports where flights are departing for the United States.”

When Microsoft (finally) trained every single one of their employees in security in the big so-called “security push” around the turn of the century, there were about a dozen insights that they really hammered home, again and again. One of the most important ones related to this was the simple insight of “if an adversary has had physical access to your computer, then it’s not your computer anymore”.

After all, if somebody has had physical access to the machine itself, then they will have been able to do everything from installing hardware keyloggers to booting the machine from USB and possibly get root access to some part of the filesystem – even on a fully encrypted GNU/Linux system, there is a small bootstrap portion that is unencrypted, and which can be compromised with assorted malware if somebody has physical access. They could conceivably even have replaced the entire processor or motherboard with hostile versions.

This is a much more probable reason for requiring all exploitable electronics to be outside of passengers’ field of view.

Remember that both the NSA and the CIA have a history of routinely pwning devices, even from the factory, or intercepting them while being shipped from the factory. (There was one incident where this was revealed last year, after the courier’s package tracking page showed how a new keyboard shipped to a Tor developer had taken a detour around the entire country, with a remarkable two-day stop – marked “delivered” – at a known NSA infiltration facility.)

Now imagine that the laptops and other large computing devices of these travelers — remember that the Tor developer in question was an American citizen! — that these devices will be required to be surrendered to the TSA, the CIA, the NSA, the TLA, and the WTF for several hours while inflight. It’s just not your device anymore when you get it back from the aircraft’s luggage hold – if it was ever there.
If your laptop has been checked in and has been in the TSA’s control, it can no longer be considered your laptop. Any further login to the compromised laptop will compromise your encrypted data, too.

The choice of the ten particular airports is also interesting. It’s the key airports of Dubai, Turkey, Egypt, Saudi Arabia, Kuwait… all predominantly Muslim countries. Some have pointed this out as racial profiling, but there are signs it may be something else entirely and more worrying.

For example, the Intercept presents the measure as a “muslim laptop ban”. The might or might not be an accurate framing, but the worrying part is that this is a best case scenario. More likely, it is a so-called “political test balloon” to check for how much protesting erupts, and to put it bluntly, if they get away with it. If they do, then this can be a precursor to a much wider ban on in-flight laptops – or, as you would more correctly have it, a much wider access for three-letter agencies to people’s laptops and data.

Privacy remains your own responsibility.

With Windows 10, Microsoft Blatantly Disregards User Choice and Privacy: A Deep Dive

With Windows 10, Microsoft Blatantly Disregards User Choice and Privacy: A Deep Dive


Microsoft had an ambitious goal with the launch of Windows 10: a billion devices running the software by the end of 2018. In its quest to reach that goal, the company aggressively pushed Windows 10 on its users and went so far as to offer free upgrades for a whole year. However, the company’s strategy for user adoption has trampled on essential aspects of modern computing: user choice and privacy. We think that’s wrong.

You don’t need to search long to come across stories of people who are horrified and amazed at just how far Microsoft has gone in order to increase Windows 10’s install base. Sure, there is some misinformation and hyperbole, but there are also some real concerns that current and future users of Windows 10 should be aware of. As the company is currently rolling out its “Anniversary Update” to Windows 10, we think it’s an appropriate time to focus on and examine the company’s strategy behind deploying Windows 10.

Disregarding User Choice

The tactics Microsoft employed to get users of earlier versions of Windows to upgrade to Windows 10 went from annoying to downright malicious. Some highlights: Microsoft installed an app in users’ system trays advertising the free upgrade to Windows 10. The app couldn’t be easily hidden or removed, but some enterprising users figured out a way. Then, the company kept changing the app and bundling it into various security patches, creating a cat-and-mouse game to uninstall it.

Eventually, Microsoft started pushing Windows 10 via its Windows Update system. It started off by pre-selecting the download for users and downloading it on their machines. Not satisfied, the company eventually made Windows 10 a recommended update so users receiving critical security updates were now also downloading an entirely new operating system onto their machines without their knowledge. Microsoft even rolled in the Windows 10 ad as part of an Internet Explorer security patch. Suffice to say, this is not the standard when it comes to security updates, and isn’t how most users expect them to work. When installing security updates, users expect to patch their existing operating system, and not see an advertisement or find out that they have downloaded an entirely new operating system in the process.

In May 2016, in an action designed in a way we think was highly deceptive, Microsoft actually changed the expected behavior of a dialog window, a user interface element that’s been around and acted the same way since the birth of the modern desktop. Specifically, when prompted with a Windows 10 update, if the user chose to decline it by hitting the ‘X’ in the upper right hand corner, Microsoft interpreted that as consent to download Windows 10.

Time after time, with each update, Microsoft chose to employ questionable tactics to cause users to download a piece of software that many didn’t want. What users actually wanted didn’t seem to matter. In an extreme case, members of a wildlife conservation group in the African jungle felt that the automatic download of Windows 10 on a limited bandwidth connection could have endangered their lives if a forced upgrade had begun during a mission.

Disregarding User Privacy

The trouble with Windows 10 doesn’t end with forcing users to download the operating system. By default, Windows 10 sends an unprecedented amount of usage data back to Microsoft, and the company claims most of it is to “personalize” the software by feeding it to the OS assistant called Cortana. Here’s a non-exhaustive list of data sent back: location data, text input, voice input, touch input, webpages you visit, and telemetry data regarding your general usage of your computer, including which programs you run and for how long.

While we understand that many users find features like Cortana useful, and that such features would be difficult (though not necessarily impossible) to implement in a way that doesn’t send data back to the cloud, the fact remains that many users would much prefer to opt out of these features in exchange for maintaining their privacy.

And while users can opt-out of some of these settings, it is not a guarantee that your computer will stop talking to Microsoft’s servers. A significant issue is the telemetry data the company receives. While Microsoft insists that it aggregates and anonymizes this data, it hasn’t explained just how it does so. Microsoft also won’t say how long this data is retained, instead providing only general timeframes. Worse yet, unless you’re an enterprise user, no matter what, you have to share at least some of this telemetry data with Microsoft and there’s no way to opt-out of it.

Microsoft has tried to explain this lack of choice by saying that Windows Update won’t function properly on copies of the operating system with telemetry reporting turned to its lowest level. In other words, Microsoft is claiming that giving ordinary users more privacy by letting them turn telemetry reporting down to its lowest level would risk their security since they would no longer get security updates1. (Notably, this is not something many articles about Windows 10 have touched on.)

But this is a false choice that is entirely of Microsoft’s own creation. There’s no good reason why the types of data Microsoft collects at each telemetry level couldn’t be adjusted so that even at the lowest level of telemetry collection, users could still benefit from Windows Update and secure their machines from vulnerabilities, without having to send back things like app usage data or unique IDs like an IMEI number.

And if this wasn’t bad enough, Microsoft’s questionable upgrade tactics of bundling Windows 10 into various levels of security updates have also managed to lower users’ trust in the necessity of security updates. Sadly, this has led some people to forego security updates entirely, meaning that there are users whose machines are at risk of being attacked.

There’s no doubt that Windows 10 has some great security improvements over previous versions of the operating system. But it’s a shame that Microsoft made users choose between having privacy and security.

The Way Forward

Microsoft should come clean with its user community. The company needs to acknowledge its missteps and offer real, meaningful opt-outs to the users who want them, preferably in a single unified screen. It also needs to be straightforward in separating security updates from operating system upgrades going forward, and not try to bypass user choice and privacy expectations.

Otherwise it will face backlash in the form of individual lawsuits, state attorney general investigations, and government investigations.

We at EFF have heard from many users who have asked us to take action, and we urge Microsoft to listen to these concerns and incorporate this feedback into the next release of its operating system. Otherwise, Microsoft may find that it has inadvertently discovered just how far it can push its users before they abandon a once-trusted company for a better, more privacy-protective solution.
  • 1. Confusingly, Microsoft calls the lowest level of telemetry reporting (which is not available on Home or Professional editions of Windows 10) the “security” level—even though it prevents security patches from being delivered via Windows Update.
