A gaggle of safety researchers found a critical vulnerability within the internet portal of the South Korean automobile producer Kia, which allowed automobiles to be hacked remotely and their homeowners tracked. To hold out the hack, solely the sufferer’s automobile license plate quantity was wanted. Let’s dive into the main points.
Overly related automobiles
If you consider it, within the final couple of a long time, automobiles have primarily turn into huge computer systems on wheels. Even the much less “good” fashions are full of electronics and geared up with a spread of sensors — from sonars and cameras to movement detectors and GPS.
And never solely that; lately, these computer systems have been continually related to the web — with all the following dangers. Not way back, we wrote about how immediately’s automobiles accumulate big quantities of information about their homeowners and ship it to the producer. Furthermore, the producers additionally promote this collected knowledge to different firms — notably insurers.
Nevertheless, there’s one other facet to this subject: being continually related to the web implies that, if there are vulnerabilities — both within the automobile itself or within the cloud system it communicates with — somebody may exploit them to hack the system and observe the automobile’s proprietor with out the producer even realizing.
The so-called “head unit” of a automobile is simply the tip of the iceberg; in actual fact, immediately’s automobiles are filled with electronics
One bug to rule all of them, one bug to seek out them
That is precisely what occurred on this case. Researchers discovered a vulnerability in Kia’s internet portal, which is utilized by Kia homeowners and sellers. It turned out that through the use of the API, the portal allowed anybody to register as a automobile supplier with only a few pretty easy strikes.

This gave the attacker entry to options that even automobile sellers shouldn’t have — no less than, not as soon as the automobile has been handed over to the client. Particularly, the portal permits first discovering any Kia automobile, after which accessing the proprietor’s knowledge (identify, telephone quantity, e-mail deal with, and even bodily deal with) — all with simply the automobile’s VIN quantity.
It needs to be famous that VIN numbers aren’t precisely secret data — in some nations, they’re publicly obtainable. For example, within the USA there are various on-line companies you should use to lookup a VIN quantity utilizing a automobile’s license plate quantity.
A common scheme of the Kia internet portal assault, permitting management over any automobile utilizing its VIN quantity. Supply
After efficiently discovering the automobile, the attacker can use the proprietor’s knowledge to register any attacker-controlled account in Kia’s system as a brand new consumer for the automobile. From there, the attacker would acquire entry to numerous features usually obtainable to the automobile’s precise proprietor via the cell app.
What’s notably attention-grabbing is that every one these options weren’t simply obtainable to the supplier who offered that automobile, however to any supplier registered in Kia’s system.
Hacking a automobile in seconds
The researchers then developed an experimental app that would take management of any Kia automobile inside seconds just by getting into its license plate quantity into the enter fields. The app would robotically discover the automobile’s VIN via the related service and use it to register the automobile to the researchers’ account.
The researchers even created a useful app to simplify hacking — all you want is the Kia automobile’s license plate quantity. Supply
After that, a single button press within the app would permit the attacker to acquire the automobile’s present coordinates, lock or unlock the doorways, begin or cease the engine, or honk the horn.
The app may very well be used to acquire the hacked automobile’s coordinates and ship instructions. Supply
It’s necessary to notice that most often these features wouldn’t be sufficient to steal the automobile. Trendy fashions are often geared up with immobilizers, which require the bodily presence of the important thing to be disabled. There are some exceptions, however usually these are the most cost effective automobiles which can be unlikely to be of a lot curiosity to thieves.
However, this vulnerability may simply be used to trace the automobile proprietor, steal valuables left contained in the automobile (or plant one thing there), or just disrupt the motive force’s life with sudden actions from the automobile.
The researchers adopted accountable disclosure protocol, informing the producer of the problem and solely publishing their findings after Kia mounted the bug. Nevertheless, they word that they’ve discovered comparable vulnerabilities earlier than and are assured they’ll proceed to find extra sooner or later.
