Free Societies are at a Disadvantage in National Cybersecurity

Jack Goldsmith and Stuart Russell just published an interesting paper, making the case that free and democratic nations are at a structural disadvantage in nation-on-nation cyberattack and defense. From a blog post:

It seeks to explain why the United States is struggling to deal with the “soft” cyber operations that have been so prevalent in recent years: cyberespionage and cybertheft, often followed by strategic publication; information operations and propaganda; and relatively low-level cyber disruptions such as denial-of-service and ransomware attacks. The main explanation is that constituent elements of U.S. society — a commitment to free speech, privacy and the rule of law; innovative technology firms; relatively unregulated markets; and deep digital sophistication — create asymmetric vulnerabilities that foreign adversaries, especially authoritarian ones, can exploit. These asymmetrical vulnerabilities might explain why the United States so often appears to be on the losing end of recent cyber operations and why U.S. attempts to develop and implement policies to enhance defense, resiliency, response or deterrence in the cyber realm have been ineffective.

I have long thought this to be true. There are defensive cybersecurity measures that a totalitarian country can take that a free, open, democratic country cannot. And there are attacks against a free, open, democratic country that just don’t matter to a totalitarian country. That makes us more vulnerable. (I don’t mean to imply — and neither do Russell and Goldsmith — that this disadvantage implies that free societies are overall worse, but it is an asymmetry that we should be aware of.)

I do worry that these disadvantages will someday become intolerable. Dan Geer often said that “the price of freedom is the probability of crime.” We are willing to pay this price because it isn’t that high. As technology makes individual and small-group actors more powerful, this price will get higher. Will there be a point in the future where free and open societies will no longer be able to survive? I honestly don’t know.

New iPhone OS May Include Device-Unlocking Security

iOS 12, the next release of Apple’s iPhone operating system, may include features to prevent someone from unlocking your phone without your permission:

The feature essentially forces users to unlock the iPhone with the passcode when connecting it to a USB accessory everytime the phone has not been unlocked for one hour. That includes the iPhone unlocking devices that companies such as Cellebrite or GrayShift make, which police departments all over the world use to hack into seized iPhones.

“That pretty much kills [GrayShift’s product] GrayKey and Cellebrite,” Ryan Duff, a security researcher who has studied iPhone and is Director of Cyber Solutions at Point3 Security, told Motherboard in an online chat. “If it actually does what it says and doesn’t let ANY type of data connection happen until it’s unlocked, then yes. You can’t exploit the device if you can’t communicate with it.”

This is part of a bunch of security enhancements in iOS 12:

Other enhancements include tools for generating strong passwords, storing them in the iCloud keychain, and automatically entering them into Safari and iOS apps across all of a user’s devices. Previously, standalone apps such as 1Password have done much the same thing. Now, Apple is integrating the functions directly into macOS and iOS. Apple also debuted new programming interfaces that allow users to more easily access passwords stored in third-party password managers directly from the QuickType bar. The company also announced a new feature that will flag reused passwords, an interface that autofills one-time passwords provided by authentication apps, and a mechanism for sharing passwords among nearby iOS devices, Macs, and Apple TVs.

A separate privacy enhancement is designed to prevent websites from tracking people when using Safari. It’s specifically designed to prevent share buttons and comment code on webpages from tracking people’s movements across the Web without permission or from collecting a device’s unique settings such as fonts, in an attempt to fingerprint the device.

The last additions of note are new permission dialogues macOS Mojave will display before allowing apps to access a user’s camera or microphone. The permissions are designed to thwart malicious software that surreptitiously turns on these devices in an attempt to spy on users. The new protections will largely mimic those previously available only through standalone apps such as one called Oversight, developed by security researcher Patrick Wardle. Apple said similar dialog permissions will protect the file system, mail database, message history, and backups.

The US Is Unprepared for Election-Related Hacking in 2018

This survey and report is not surprising:

The survey of nearly forty Republican and Democratic campaign operatives, administered through November and December 2017, revealed that American political campaign staff — primarily working at the state and congressional levels — are not only unprepared for possible cyber attacks, but remain generally unconcerned about the threat. The survey sample was relatively small, but nevertheless the survey provides a first look at how campaign managers and staff are responding to the threat.

The overwhelming majority of those surveyed do not want to devote campaign resources to cybersecurity or to hire personnel to address cybersecurity issues. Even though campaign managers recognize there is a high probability that campaign and personal emails are at risk of being hacked, they are more concerned about fundraising and press coverage than they are about cybersecurity. Less than half of those surveyed said they had taken steps to make their data secure and most were unsure if they wanted to spend any money on this protection.

Security is never something we actually want. Security is something we need in order to avoid what we don’t want. It’s also more abstract, concerned with hypothetical future possibilities. Of course it’s lower on the priorities list than fundraising and press coverage. They’re more tangible, and they’re more immediate.

This is all to the attackers’ advantage.

Cybersecurity Insurance

Good article about how difficult it is to insure an organization against Internet attacks, and how expensive the insurance is.

Companies like retailers, banks, and healthcare providers began seeking out cyberinsurance in the early 2000s, when states first passed data breach notification laws. But even with 20 years’ worth of experience and claims data in cyberinsurance, underwriters still struggle with how to model and quantify a unique type of risk.

“Typically in insurance we use the past as prediction for the future, and in cyber that’s very difficult to do because no two incidents are alike,” said Lori Bailey, global head of cyberrisk for the Zurich Insurance Group. Twenty years ago, policies dealt primarily with data breaches and third-party liability coverage, like the costs associated with breach class-action lawsuits or settlements. But more recent policies tend to accommodate first-party liability coverage, including costs like online extortion payments, renting temporary facilities during an attack, and lost business due to systems failures, cloud or web hosting provider outages, or even IT configuration errors.

In my new book — out in September — I write:

There are challenges to creating these new insurance products. There are two basic models for insurance. There’s the fire model, where individual houses catch on fire at a fairly steady rate, and the insurance industry can calculate premiums based on that rate. And there’s the flood model, where an infrequent large-scale event affects large numbers of people — but again at a fairly steady rate. Internet+ insurance is complicated because it follows neither of those models but instead has aspects of both: individuals are hacked at a steady (albeit increasing) rate, while class breaks and massive data breaches affect lots of people at once. Also, the constantly changing technology landscape makes it difficult to gather and analyze the historical data necessary to calculate premiums.

Jumping Air Gaps

Nice profile of Mordechai Guri, who researches a variety of clever ways to steal data over air-gapped computers.

Guri and his fellow Ben-Gurion researchers have shown, for instance, that it’s possible to trick a fully offline computer into leaking data to another nearby device via the noise its internal fan generates, by changing air temperatures in patterns that the receiving computer can detect with thermal sensors, or even by blinking out a stream of information from a computer hard drive LED to the camera on a quadcopter drone hovering outside a nearby window. In new research published today, the Ben-Gurion team has even shown that they can pull data off a computer protected by not only an air gap, but also a Faraday cage designed to block all radio signals.

Here’s a page with all the research results.
