Thwarting Vehicle Keyless Fob Attacks

A recent article in Wired called “Radio Attack Lets Hackers Steal 24 Different Car Models” at https://www.wired.com/2016/03/study-finds-24-car-models-open-unlocking-ignition-hack/ talks about how thieves can steal some car models by attacking keyless entry fobs.

It is a very informative article, but they do not talk much about possible solutions. Want to wait around while your automobile manufacturer comes up with a solution?

Our own cars—a 2015 Honda Accord and a manual-everything 2005 Honda Civic—are not on the list of vulnerable vehicles. While the 2005 Honda, which does not have keyless entry, is not susceptible to this type of radio attack, the 2015 Honda Accord might be. Although it was not one of the vehicles listed in the article, it might not have been one of the models tested. I looked at my key fob to see if there was some easy way to shut off keyless entry. Aside from taking out the battery, none was apparent. A switch on the key fob in a location that is not easily turned on or off (maybe inside the battery case) would be a great solution to this problem. Another possible plus? It might make the battery last longer!

When I Googled “2015 Honda Accord turn off keyless entry,” there were not many new solutions. Possible solutions include:

  • Removing the key fob battery. According to a YouTube video by Honda Pro, https://www.youtube.com/watch?v=kXiyku7Ye-c, the car will not start when the key is not in the car. However, it will still start when the key fob is present even if the battery is inoperative or removed. The key fob also contains a manual key, so entry is still available.
  • Making or buying a faraday cage. There are several types of faraday cages. According to Wikipedia, a faraday cage “is an enclosure used to block electromagnetic fields.” I tried wrapping my key in aluminum foil. Standing next to the 2015 Honda with the key wrapped in aluminum foil, I could still unlock the car. However, while I did not test it, it might limit the accessible distance for the key signal.

I do not like the option of putting my keys in the freezer, which is often touted as an easy faraday cage. For one thing, the moisture and the cold could be hard on the key electronics. Replacing the key is expensive and you would still have the problem with the new key. Another problem with this solution is that it only works when you have access to a refrigerator. Probably would not work at Starbucks!

Amazon.com offers Faraday pouches for sale for as little as $9 (plus shipping). There is a DIY faraday cage Instructable at http://www.instructables.com/id/Faraday-Cage-Phone-Pouch/ if you would like to make one yourself.

If anyone has other ideas about possible solutions to a keyless entry attack, leave a comment and I will update the article.

Remember, always lock your car, do not leave extra keys in hidden places on the vehicle, and remove or hide your valuables before you leave your car. It is also a good idea to remove your garage door opener from the car, especially if you leave the door between the house and the garage open.

Sony …. holding out for a hero!

On 11/24/2014, the Guardians of Peace (#GOP) announced on Reddit that they had hacked Sony Pictures Entertainment’s network, alleging that #GOP had stolen 100 terabytes of data. The stolen data laid out for public consumption in various data dumps around the Internet included both employee information—social security numbers, dates of birth, medical records, salary information—and corporate information—spreadsheets containing Sony layoff information, business plans, their network architecture, movie scripts, and even actual movies—and other confidential information. Then the attackers destroyed data to emphasize that their demands were serious.

While Sony has not commented much publicly except to yank The Interview (formerly scheduled to be released on Christmas Day), there has been considerable speculation on the person or groups responsible. The story—as we know it at this moment—sounds like a movie plot. (Are you listening Sony? When ya gonna make this movie?) There are spies, hacking, extortion … all the elements of a great plot … except a hero/heroine.

Sony, you get to play the whimpering coward sniveling in the corner. Who is going to step up to be the hero or heroine? That is the real question. Bonnie Tyler says it best, I am holding out for a hero/heroine.

As I see it there are four possible hacker group combinations:

  • The North Koreans hacked Sony because of the movie Sony produced called The Interview. It’s a comedy, and probably not a very good one.
  • One or more disgruntled Sony employees took the data. To look for possible disgruntled employees, let’s count: How many people has Sony laid-off?
  • The North Koreans and the disgruntled employees (and possibly other groups) separately hacked Sony.
  • The North Koreans managed to get someone inside Sony.

In my opinion, stealing 100 terabytes of data took some time and someone inside Sony had to help. How did they get the data out? USB drives? According to Numion.com, to download 100 terabytes at 10 Gbps with 50% overhead would take over 33 hours! Also, the data sounds like it’s very organized. Whoever stole it knew where to look and what to take and what to post first to make it hurt. It has a personal feel to it. No, it’s more than the North Koreans.

For a more in-depth analysis of the hackers, read Why the Sony hack is unlikely to be the work of North Korea.

North Korea: if you’re reading this, it’s just a movie. Get a sense of humor! Americans have made several movies about US presidents getting assassinated; here’s a few examples:

And of course, Wag the Dog cannot be left out of any movie list that discusses the death of a president’s political life.

I agree with President Obama that pulling the movie was a mistake. This is not a movie that I would have wanted to see, much less paid for. If you’d let it run, it would have been a brief news article, a week or two in the theaters and then … consigned to the $5 bin in Walmart. Now I want to see it!

However, there are some lessons we can all learn here:

  • Email is not private. Before you send any email, decide how you would feel if it ended up on the front page of the New York Times.
  • This is not the first time Sony has been publicly hacked. Remember the PlayStation Network debacle in April 2011, which affected 77 million customer accounts? This was followed by an attack May 2, 2011, on 24.5 million accounts at Sony Online Entertainment. Did Sony learn anything from those two incidents? Apparently not.
  • Compliance is not security! Doing the minimum necessary to comply with a law or laws is not enough to keep your corporate or personal information safe.
  • Just because you have a security breach doesn’t mean you have to lose a 100 terabytes of data. What were Sony’s security people doing?
  • If the company you work for does not take information security and privacy seriously, find someplace else to work. According to Forbes.com, Sony has had 195 security breaches from September 1, 2013 through June 30, 2014, according to leaked emails. However, it’s hard to determine the seriousness of the incidents from the information presented in the article. Were any of these breaches about tons of data spewing from Sony?

How can you tell if your employer is taking information security and privacy seriously? Do they say “information security is important” but cut the budget? Do they train employees on information security and privacy? Do they patch their systems and keep their software updated? Have they had a breach? What did they do?

  • If the company that you buy goods or services from does not protect your information, take your business elsewhere.

Vote with your feet and your money! Protect your information; there’s no one that it matters more to than you.

My bottom line? I’m outraged—both at Sony’s sloppy information security practices and their cowardice.
