Another Attack Against Driverless Cars

In this piece of research, attackers successfully attack a driverless car system — Renault Captur’s “Level 0” autopilot (Level 0 systems advise human drivers but do not directly operate cars) — by following them with drones that project images of fake road signs in 100ms bursts. The time is too short for human perception, but long enough to fool the autopilot’s sensors.

Resetting Your GE Smart Light Bulb

If you need to reset the software in your GE smart light bulb — firmware version 2.8 or later — just follow these easy instructions:

Start with your bulb off for at least 5 seconds.

  1. Turn on for 8 seconds
  2. Turn off for 2 seconds
  3. Turn on for 8 seconds
  4. Turn off for 2 seconds
  5. Turn on for 8 seconds
  6. Turn off for 2 seconds

A “Department of Cybersecurity”

Presidential candidate John Delaney has announced a plan to create a Department of Cybersecurity.

I have long been in favor of a new federal agency to deal with Internet — and especially Internet of Things — security. The devil is in the details, of course, and it’s really easy to get this wrong. In Click Here to Kill Everybody, I outline a strawman proposal; I call it the “National Cyber Office” and model it on the Office of the Director of National Intelligence. But regardless of what you think of this idea, I’m glad that at least someone is talking about it.

Slashdot thread. News story.

EDITED TO ADD: Yes, this post is perilously close to presidential politics. Any comment that opines on the qualifications of this, or any other, presidential candidate will be deleted.

Zipcar Disruption

This isn’t a security story, but it easily could have been. Last Saturday, Zipcar had a system outage: “an outage experienced by a third party telecommunications vendor disrupted connections between the company’s vehicles and its reservation software.”

That didn’t just mean people couldn’t get cars they reserved. Sometimes is meant they couldn’t get the cars they were already driving to work:

Andrew Jones of Roxbury was stuck on hold with customer service for at least a half-hour while he and his wife waited inside a Zipcar that would not turn back on after they stopped to fill it up with gas.

“We were just waiting and waiting for the call back,” he said.

Customers in other states, including New York, California, and Oregon, reported a similar problem. One user who tweeted about issues with a Zipcar vehicle listed his location as Toronto.

Some, like Jones, stayed with the inoperative cars. Others, including Tina Penman in Portland, Ore., and Heather Reid in Cambridge, abandoned their Zipcar. Penman took an Uber home, while Reid walked from the grocery store back to her apartment.

This is a reliability issue that turns into a safety issue. Systems that touch the direct physical world like this need better fail-safe defaults.

An Argument that Cybersecurity Is Basically Okay

Andrew Odlyzko’s new essay is worth reading — “Cybersecurity is not very important“:

Abstract: There is a rising tide of security breaches. There is an even faster rising tide of hysteria over the ostensible reason for these breaches, namely the deficient state of our information infrastructure. Yet the world is doing remarkably well overall, and has not suffered any of the oft-threatened giant digital catastrophes. This continuing general progress of society suggests that cyber security is not very important. Adaptations to cyberspace of techniques that worked to protect the traditional physical world have been the main means of mitigating the problems that occurred. This “chewing gum and baling wire”approach is likely to continue to be the basic method of handling problems that arise, and to provide adequate levels of security.

I am reminded of these two essays. And, as I said in the blog post about those two essays:

This is true, and is something I worry will change in a world of physically capable computers. Automation, autonomy, and physical agency will make computer security a matter of life and death, and not just a matter of data.

The Latest in Creepy Spyware

The Nest home alarm system shipped with a secret microphone, which — according to the company — was only an accidental secret:

On Tuesday, a Google spokesperson told Business Insider the company had made an “error.”

“The on-device microphone was never intended to be a secret and should have been listed in the tech specs,” the spokesperson said. “That was an error on our part.”

Where are the consumer protection agencies? They should be all over this.

And while they’re figuring out which laws Google broke, they should also look at American Airlines. Turns out that some of their seats have built-in cameras:

American Airlines spokesperson Ross Feinstein confirmed to BuzzFeed News that cameras are present on some of the airlines’ in-flight entertainment systems, but said “they have never been activated, and American is not considering using them.” Feinstein added, “Cameras are a standard feature on many in-flight entertainment systems used by multiple airlines. Manufacturers of those systems have included cameras for possible future uses, such as hand gestures to control in-flight entertainment.”

That makes it all okay, doesn’t it?

Actually, I kind of understand the airline seat camera thing. My guess is that whoever designed the in-flight entertainment system just specced a standard tablet computer, and they all came with unnecessary features like cameras. This is how we end up with refrigerators with Internet connectivity and Roombas with microphones. It’s cheaper to leave the functionality in than it is to remove it.

Still, we need better disclosure laws.

Security Analysis of the LIFX Smart Light Bulb

The security is terrible:

In a very short limited amount of time, three vulnerabilities have been discovered:

  • Wifi credentials of the user have been recovered (stored in plaintext into the flash memory).
  • No security settings. The device is completely open (no secure boot, no debug interface disabled, no flash encryption).
  • Root certificate and RSA private key have been extracted.

Japanese Government Will Hack Citizens’ IoT Devices

The Japanese government is going to run penetration tests against all the IoT devices in their country, in an effort to (1) figure out what’s insecure, and (2) help consumers secure them:

The survey is scheduled to kick off next month, when authorities plan to test the password security of over 200 million IoT devices, beginning with routers and web cameras. Devices in people’s homes and on enterprise networks will be tested alike.

[…]

The Japanese government’s decision to log into users’ IoT devices has sparked outrage in Japan. Many have argued that this is an unnecessary step, as the same results could be achieved by just sending a security alert to all users, as there’s no guarantee that the users found to be using default or easy-to-guess passwords would change their passwords after being notified in private.

However, the government’s plan has its technical merits. Many of today’s IoT and router botnets are being built by hackers who take over devices with default or easy-to-guess passwords.

Hackers can also build botnets with the help of exploits and vulnerabilities in router firmware, but the easiest way to assemble a botnet is by collecting the ones that users have failed to secure with custom passwords.

Securing these devices is often a pain, as some expose Telnet or SSH ports online without the users’ knowledge, and for which very few users know how to change passwords. Further, other devices also come with secret backdoor accounts that in some cases can’t be removed without a firmware update.

I am interested in the results of this survey. Japan isn’t very different from other industrialized nations in this regard, so their findings will be general. I am less optimistic about the country’s ability to secure all of this stuff — especially before the 2020 Summer Olympics.

Hacking Construction Cranes

Construction cranes are vulnerable to hacking:

In our research and vulnerability discoveries, we found that weaknesses in the controllers can be (easily) taken advantage of to move full-sized machines such as cranes used in construction sites and factories. In the different attack classes that we’ve outlined, we were able to perform the attacks quickly and even switch on the controlled machine despite an operator’s having issued an emergency stop (e-stop).

The core of the problem lies in how, instead of depending on wireless, standard technologies, these industrial remote controllers rely on proprietary RF protocols, which are decades old and are primarily focused on safety at the expense of security. It wasn’t until the arrival of Industry 4.0, as well as the continuing adoption of the industrial internet of things (IIoT), that industries began to acknowledge the pressing need for security.
