US Issues Hacking Security Alert for Small Planes (securityweek.com) 70

wiredmikey writes: The DHS has issued a security alert for small planes, warning that modern flight systems are vulnerable to hacking if someone manages to gain physical access to the aircraft. The alert stems from research done by security firm Rapid7, which found that an attacker could potentially disrupt electronic messages transmitted across a small plane's network, for example by attaching a small device to its wiring, that would affect aircraft systems. Engine readings, compass data, altitude and other readings "could all be manipulated to provide false measurements to the pilot," according to the DHS alert.

          or, you know, just steal the spark plugs or cut ignition wires if you didn't want to KILL anyone but just stop the plane.

        That, and getting down safely when the electronic instruments go all wibbley-wobbley is a skill every pilot has to know and demonstrate to get their ratings.

          Sure, but honestly I don't think pilots even have to worry about it as I suspect the occurrences of small aircraft sabotage are pretty close to limited to a few members of criminal enterprise...

      Reading TFA (https://www.us-cert.gov/ics/alerts/ics-alert-19-211-01) they are saying that there are things that car manufacturers have already done to mitigate some of this stuff, and aircraft manufacturers should do the same.

      That seems reasonable. I don't know if aircraft have a diagnostic port like cars, but if they do and it's not firewalled then it would be fairly easy to install something there without having to do any major surgery. It also stops compromise of one system allowing the attacker to easil

      Physically cut wires will cause the aircraft to fail its preflight checks. They will simply be repaired on the ground. Inconvenient, but not dangerous in practice. (No sane pilot ignore skips his preflight.)

      Compromised avionics can take down a plane in flight.

        If an attacker has enough physical access that they can install a black box in the avionics wiring, they can install a bomb that can also take down a plane in flight.

        This seems more like an case of weak physical security than an avionics vulnerability.

    if i would want to kill someone while aving access to the wiring, i would simply put a timer that when the power is on, it would countdown and have something ignite at the end of that timer, burning all wires and you're done! why complicate things with a dongle that changes values, unless you're in a night flight, any pilot should be abel to tell that his instruments are not making any sense...

    Anything generating fake signals can mess with a system made to receive radio signals. Any pilot looking outside the window is going to detect the false readings in a very quick timeline. Yes, you can send false gps signals, or VOR, or add magnetic interference on a compass. My plane has 2 seperate GPS receivers built in, plus my Stratus handheld, plus my Ipad's gps, plus my VOR receivers, plus my compass, plus the fact I can look out the windows and look at my charts and see that things look wrong. Good luck faking out all my systems even though there's no encrypted or trusted communication system in place.

    I guess you could muck with the gauge readings, but every pilot also knows the patterns and would recognize that things look abnormal in short order. The only thing I think that would boggle me is if the interference managed to make my fuel senders read accurate for a change.

    Aircraft have simple and easy to verify systems. This is more of a threat for automated things like drones that can be duped into following bad signals. Planes have people with brains and training (trust the instruments but also always compare to see if one is malfunctioning and train on how to ignore bad readings). Since we specifically train to expect things to break or screw up, the threat level is pretty low. They would have to get all the systems to agree, I doubt a 5 minute part added into a wire will do that.

    • Excellent take on the situation, would mod this up if I hadn't already posted.

    • Indeed. How is putting a malicious device on the CAN bus any different than surreptitiously adding a resistor in-between the nav radio receiver and the glideslope indicator, causing the analog glideslope meter needle to indicate higher than actual? Is DHS going to issue a security alert for soldering irons?

      In any case, if you under ATC control, they are going to get on your back pretty quickly if you significantly deviate from your assigned course / altitude. And if you are not under ATC control, you

    I'm so glad my modern road vehicle CAN not be attacked like this!

  • Anybody competent with physical access can do extreme damage. Not new and not surprising.

  • Are big planes immune to this type of physical attack? How about medium planes? Or those little drones? And how about big nuclear missiles - are they immune if someone gets in there with a screw driver, a tesla coil, and a Raspberry Pi?

  • If you look into the FAA data, you'll find that seaplanes from firms like Horizon Air that operates out of Lake Union in the heart of Seattle with an unlicensed airport that was never agreed to, don't even have transponders, and are very vulnerable to attacks like this, which are fairly easy to accomplish.

    Plus, they continually violate both noise and hours of operation requirements for flying over residential communities and schools, and like to buzz large towers, which we all know no terrorist would ever w

      Horizon Air does not operate out of Lake Union. They have no floatplanes in their fleet at all. If they tried to land a Q400 in Lake Union it would make a very big splash. Kenmore Air and Seattle Seaplanes do operate out of Lake Union. Both of their airport operating areas are licensed, approved, inspected, and monitored by the FAA. The airport identifiers are W55, and 0W0, respectively. W55 was approved and started operating in September 1947, and 0W0 in April 1986. All of their aircraft not only hav

    A lot of small planes have automobile engines in them. I'd be a little surprised if they changed the wiring harness. To that end, anyone with a cheap arduino and a canbus/obd2 adapter (for anything built after 1995) can inject all kinds of bad data into the cars network if they wanted to. Doubt it's any different.

      Very, very few small planes have automobile engines in them. No certified aircraft use automobile engines, and even in experimental homebuilt aviation it is not common, accounting for ~10ish of all installations. Search for "Statistical Analysis of Homebuilt Aircraft Engines" by Ron Wanttaja. Of the ones that do use automobile engines, by far the most common are air-cooled VW and Corvair engines form the 1960's. Ain't no OBD to hack there. In general, automotive engines are heavier and less reliable than aircraft engines models which have been in production since the 1940s-50's. They do have better fuel burn though.
  • So someone with physical access to sensors can do bad things. So DHS has learn about the basics of computing "Garbage in, garbage out"?

    I think Charles Babbage said it well in 1864:
    On two occasions I have been asked, "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
  • I've said this numerous times of anything tech - if I've got physical access, all bets are off. How is this news?

    Unless of course someone plants something on the CAN bus on your plane .... ?

    • Anyone who didn't already know this for decades either isn't paying any attention, or wasn't born yet.

      Seriously, this qualifies as "news"???

  • They could also just shove a piece of gum in the pitot tube. Most Light aircraft don't even use a glass cockpit still, so aren't vulnerable
  • It turns out if you have physical access, you can put a bunch of snakes on the plane.

The truth of a proposition has nothing to do with its credibility. And vice versa.
