Security Vulnerability in Smart Electric Outlets

A security vulnerability in Belkin's Wemo Insight "smartplugs" allows hackers to not only take over the plug, but use it as a jumping-off point to attack everything else on the network.

From the Register:

The bug underscores the primary risk posed by IoT devices and connected appliances. Because they are commonly built by bolting on network connectivity to existing appliances, many IoT devices have little in the way of built-in network security.

Even when security measures are added to the devices, the third-party hardware used to make the appliances "smart" can itself contain security flaws or bad configurations that leave the device vulnerable.

"IoT devices are frequently overlooked from a security perspective; this may be because many are used for seemingly innocuous purposes such as simple home automation," the McAfee researchers wrote.

"However, these devices run operating systems and require just as much protection as desktop computers."

I'll bet you anything that the plug cannot be patched, and that the vulnerability will remain until people throw them away.

Using Hacked IoT Devices to Disrupt the Power Grid

This is really interesting research: "BlackIoT: IoT Botnet of High Wattage Devices Can Disrupt the Power Grid":

Abstract: We demonstrate that an Internet of Things (IoT) botnet of high wattage devices -- such as air conditioners and heaters -- gives a unique ability to adversaries to launch large-scale coordinated attacks on the power grid. In particular, we reveal a new class of potential attacks on power grids called the Manipulation of demand via IoT (MadIoT) attacks that can leverage such a botnet in order to manipulate the power demand in the grid. We study five variations of the MadIoT attacks and evaluate their effectiveness via state-of-the-art simulators on real-world power grid models. These simulation results demonstrate that the MadIoT attacks can result in local power outages and in the worst cases, large-scale blackouts. Moreover, we show that these attacks can rather be used to increase the operating cost of the grid to benefit a few utilities in the electricity market. This work sheds light upon the interdependency between the vulnerability of the IoT and that of the other networks such as the power grid whose security requires attention from both the systems security and power engineering communities.

I have been collecting examples of surprising vulnerabilities that result when we connect things to each other. This is a good example of that.

Five-Eyes Intelligence Services Choose Surveillance Over Security

The Five Eyes -- the intelligence consortium of the rich English-speaking countries (the US, Canada, the UK, Australia, and New Zealand) -- have issued a "Statement of Principles on Access to Evidence and Encryption" where they claim their needs for surveillance outweigh everyone's needs for security and privacy.

...the increasing use and sophistication of certain encryption designs present challenges for nations in combatting serious crimes and threats to national and global security. Many of the same means of encryption that are being used to protect personal, commercial and government information are also being used by criminals, including child sex offenders, terrorists and organized crime groups to frustrate investigations and avoid detection and prosecution.

Privacy laws must prevent arbitrary or unlawful interference, but privacy is not absolute. It is an established principle that appropriate government authorities should be able to seek access to otherwise private information when a court or independent authority has authorized such access based on established legal standards. The same principles have long permitted government authorities to search homes, vehicles, and personal effects with valid legal authority.

The increasing gap between the ability of law enforcement to lawfully access data and their ability to acquire and use the content of that data is a pressing international concern that requires urgent, sustained attention and informed discussion on the complexity of the issues and interests at stake. Otherwise, court decisions about legitimate access to data are increasingly rendered meaningless, threatening to undermine the systems of justice established in our democratic nations.

To put it bluntly, this is reckless and shortsighted. I've repeatedly written about why this can't be done technically, and why trying results in insecurity. But there's a greater principle at first: we need to decide, as nations and as society, to put defense first. We need a "defense dominant" strategy for securing the Internet and everything attached to it.

This is important. Our national security depends on the security of our technologies. Demanding that technology companies add backdoors to computers and communications systems puts us all at risk. We need to understand that these systems are too critical to our society and -- now that they can affect the world in a direct physical manner -- affect our lives and property as well.

This is what I just wrote, in Click Here to Kill Everybody:

There is simply no way to secure US networks while at the same time leaving foreign networks open to eavesdropping and attack. There's no way to secure our phones and computers from criminals and terrorists without also securing the phones and computers of those criminals and terrorists. On the generalized worldwide network that is the Internet, anything we do to secure its hardware and software secures it everywhere in the world. And everything we do to keep it insecure similarly affects the entire world.

This leaves us with a choice: either we secure our stuff, and as a side effect also secure their stuff; or we keep their stuff vulnerable, and as a side effect keep our own stuff vulnerable. It's actually not a hard choice. An analogy might bring this point home. Imagine that every house could be opened with a master key, and this was known to the criminals. Fixing those locks would also mean that criminals' safe houses would be more secure, but it's pretty clear that this downside would be worth the trade-off of protecting everyone's house. With the Internet+ increasing the risks from insecurity dramatically, the choice is even more obvious. We must secure the information systems used by our elected officials, our critical infrastructure providers, and our businesses.

Yes, increasing our security will make it harder for us to eavesdrop, and attack, our enemies in cyberspace. (It won't make it impossible for law enforcement to solve crimes; I'll get to that later in this chapter.) Regardless, it's worth it. If we are ever going to secure the Internet+, we need to prioritize defense over offense in all of its aspects. We've got more to lose through our Internet+ vulnerabilities than our adversaries do, and more to gain through Internet+ security. We need to recognize that the security benefits of a secure Internet+ greatly outweigh the security benefits of a vulnerable one.

We need to have this debate at the level of national security. Putting spy agencies in charge of this trade-off is wrong, and will result in bad decisions.

Cory Doctorow has a good reaction.

Using a Smartphone's Microphone and Speakers to Eavesdrop on Passwords

It's amazing that this is even possible: "SonarSnoop: Active Acoustic Side-Channel Attacks":

Abstract: We report the first active acoustic side-channel attack. Speakers are used to emit human inaudible acoustic signals and the echo is recorded via microphones, turning the acoustic system of a smart phone into a sonar system. The echo signal can be used to profile user interaction with the device. For example, a victim's finger movements can be inferred to steal Android phone unlock patterns. In our empirical study, the number of candidate unlock patterns that an attacker must try to authenticate herself to a Samsung S4 Android phone can be reduced by up to 70% using this novel acoustic side-channel. Our approach can be easily applied to other application scenarios and device types. Overall, our work highlights a new family of security threats.

New Book Announcement: Click Here to Kill Everybody

I am pleased to announce the publication of my latest book: Click Here to Kill Everybody: Security and Survival in a Hyper-connected World. In it, I examine how our new immersive world of physically capable computers affects our security.

I argue that this changes everything about security. Attacks are no longer just about data, they now affect life and property: cars, medical devices, thermostats, power plants, drones, and so on. All of our security assumptions assume that computers are fundamentally benign. That, no matter how bad the breach or vulnerability is, it's just data. That's simply not true anymore. As automation, autonomy, and physical agency become more prevalent, the trade-offs we made for things like authentication, patching, and supply chain security no longer make any sense. The things we've done before will no longer work in the future.

This is a book about technology, and it's also a book about policy. The regulation-free Internet that we've enjoyed for the past decades will not survive this new, more dangerous, world. I fear that our choice is no longer between government regulation and no government regulation; it's between smart government regulation and stupid regulation. My aim is to discuss what a regulated Internet might look like before one is thrust upon us after a disaster.

Click Here to Kill Everybody is available starting today. You can order a copy from Amazon, Barnes & Noble, Books-a-Million, Norton's webpage, or anyplace else books are sold. If you're going to buy it, please do so this week. First-week sales matter in this business.

Reviews so far from the Financial Times, Nature, and Kirkus.
