A cybersecurity test involving the BYD Shark 6 has raised fresh concerns about the digital security of connected vehicles sold in South Africa.

According to MyBroadband, Australian cybersecurity firm FortifyLabs demonstrated that a 2025 BYD Shark 6 Premium could be compromised through its onboard systems, allowing researchers to remotely access certain vehicle functions.

The same model is available in South Africa.

Physical Access Came First

FortifyLabs said the test was carried out for Australian broadcaster ABC’s Four Corners programme.

The cybersecurity firm explained that researchers initially needed physical access to the vehicle to install software on its infotainment system.

After that, remote connectivity was possible.

FortifyLabs said researchers could access the car’s microphone, track its real-time location and switch its headlights on and off remotely.

However, the company also said BYD had protections in place that prevented access to more sensitive systems, including the vehicle’s cameras.

Cyber Risk Extends Beyond BYD

FortifyLabs stressed that the issue was not limited to BYD or Chinese vehicle manufacturers.

The firm said connected vehicles from manufacturers in the US, Europe and Asia could also face cybersecurity risks as cars become more dependent on software and online services.

South African cybersecurity expert Boikokobetso Makhetloane echoed that warning during an interview with Jacob Moshokoa’s CarTalk.

He described modern vehicles as “computers with wheels” and said cellular connections, Bluetooth, Wi-Fi, cloud services and diagnostic ports could all become potential targets.

Drivers Urged to Keep Software Updated

Makhetloane said compromised vehicle systems could expose personal data processed between a smartphone and a car.

According to CarTalk, that could include location information, calls and other data handled through connected systems.

He advised South African motorists to keep vehicle software updated whenever manufacturers release new security patches.

MyBroadband reports that the vulnerability used during the FortifyLabs demonstration has since been patched by BYD.

Makhetloane cautioned, however, that future software vulnerabilities could still emerge.

FortifyLabs also warned motorists against assuming that connected cars are automatically secure simply because they are produced by major manufacturers.
