The increasing popularity of Car Gadgets that plug into your vehicle’s OBD2 port offers numerous benefits, from usage-based insurance tracking driving habits to real-time vehicle diagnostics. However, recent research has uncovered significant security vulnerabilities in these devices, raising serious concerns about 차량 안전 및 개인 정보 보호. This article delves into these risks, highlighting how seemingly innocuous car gadgets could become a gateway for hackers to access and potentially control your vehicle.
Security Vulnerabilities Uncovered in Common Car Gadgets
Researchers at the University of California San Diego (UCSD) conducted a study that revealed alarming security flaws in OBD2 dongles from a company named Mobile Devices, which are utilized by various telematics service providers. Coordina, a subsidiary of TomTom Telematics, uses these dongles, and initially downplayed the risks, stating the vulnerabilities were present in older versions and they were working on replacements. They argued that their devices were not susceptible to SMS hack attacks due to the private nature of their SIM card numbers. However, the UCSD researchers countered that they successfully employed brute-force methods to send SMS messages to dongles, even without knowing the SIM card numbers, although they hadn’t specifically tested this on Coordina devices.
The security concerns extend beyond just one provider. Metromile, another insurance company leveraging telematics, also utilizes OBD2 plug-in devices. Progressive, a major insurance provider, offers a similar program called Snapshot, using their OBD2 device. Earlier in the year, security researcher Corey Thuen identified serious vulnerabilities in the Progressive Snapshot device, although a proof-of-concept attack was not demonstrated. Furthermore, cybersecurity firm Argus discovered hackable flaws in Zubie, an OBD2 device designed for personal driving efficiency tracking.
The UCSD team’s investigation into Mobile Devices’ dongles specifically exposed a range of critical security weaknesses. They found that the “developer” mode was enabled, granting open SSH access to anyone scanning for the devices. Critically, all devices shared the same private key, which could be easily extracted by hackers to gain complete “root” access across any of the dongles. Adding to the severity, these dongles were configured to accept commands via SMS, a protocol known for lacking robust authentication. By sending SMS texts from a designated phone number, malicious actors could rewrite the device’s firmware or directly issue commands to the connected vehicle.
Implications for Vehicle Security and Beyond
It’s crucial to understand that these vulnerabilities are not isolated to a specific car model like the Corvette used in the UCSD tests. While Chevrolet, the maker of Corvette, did not comment, the researchers emphasized that the identified flaws could allow hijacking steering or brakes in virtually any modern vehicle equipped with a Mobile Devices dongle. UCSD researcher Karl Koscher highlighted the previous work of Charlie Miller and Chris Valasek, who demonstrated attacks on Toyota Prius and Ford Escape in 2013 via the OBD2 port, stating that “If you put this into a Prius, there are libraries of attacks ready to use online.” This underscores the broader risk affecting numerous vehicle makes and models utilizing similar car gadgets.
Mobile Devices has announced a software fix in response to the UCSD findings, and Metromile has reportedly implemented a patch. However, the UCSD researchers caution that regardless of the immediate fixes, both consumers and OBD2 device companies must prioritize the security of these in-car gadgets. Koscher advises, “Think twice about what you’re plugging into your car. It’s hard for the regular consumer to know that their device is trustworthy or not, but it’s something they should give a moment’s thought to. Is this exposing me to more risk? Am I ok with that?”
The implications extend beyond individual consumers. A White House executive order in March encouraged federal agencies with large vehicle fleets to adopt telematics systems for improved vehicle efficiency. This could lead to a significant increase in government vehicles using internet-connected dongles, potentially amplifying the scale of vulnerability if security is not adequately addressed.
UCSD’s Savage concludes, “We have a whole bunch of these that are already out there in the market. Given that we’ve seen a complete remote exploit and these things aren’t regulated in any way and their use is growing…I think it’s a fair assessment that yes, there will be problems elsewhere.” This emphasizes the urgent need for increased awareness, stricter security standards, and proactive measures to safeguard against potential exploitation of car gadgets.
