Wireless update tech in vehicles raises cybersecurity concerns
Experts warn widespread OTA technology in automotive sector is vulnerable to cyber attacks
1What is OTA technology?
Over-the-air (OTA) technology enables wireless updates of software, firmware and data to internet-connected vehicles. First introduced by Tesla in 2012 for Model S, this system is now adopted by many automotive manufacturers globally.
2Benefits and risks
While OTA provides advantages like remote vehicle updates without recalls, experts warn it creates vulnerabilities. Foreign actors could potentially take control of moving vehicles through cyber attacks targeting these systems.
3Tests in Norway
Norwegian bus company Ruter's tests last year revealed security flaws in OTA systems of Chinese-made Yutong buses. Researchers found battery and power systems could be accessed remotely via a Romanian SIM card.
4National security concerns
Gabriel Lim, senior analyst at a Singapore research institute, calls OTA 'a unique national security concern'. Countries like Norway, Denmark and the UK are urging stronger safeguards against these emerging risks.
5Industry expansion
OTA technology is spreading beyond automotive to maritime, rail, aerospace and industrial machinery sectors. This expansion makes robust cybersecurity measures increasingly critical across transportation infrastructure.
6Expert recommendations
Experts call for greater transparency in OTA system implementation. Recommendations include restrictions on foreign-made hardware/software, transparent data collection processes, and additional security reviews to mitigate risks.
