BYD EVs Exposed as Cybersecurity Risks, But Debate Rages Over Global Surveillance Concerns

Post date: September 21, 2026 · Discovered: September 22, 2026 · 3 posts, 66 comments

A cybersecurity researcher demonstrated that BYD EVs could be hacked to access sensitive data and control vehicle functions with minimal effort, sparking alarm over potential surveillance risks. The exploit allowed access to a driver's microphone, which was used to capture a call where the driver shared internet banking passwords. This incident has ignited a heated debate over the security of Chinese-made EVs and broader concerns about data collection by all modern vehicles.

Commenters are sharply divided. Some, like 'Tiral', argue that BYD is a CCP-owned company that blocks the internet and monitors communication, making its EVs inherently compromised for surveillance. Others, such as 'RedWizard', claim that Western brands like Tesla and Toyota also collect vast amounts of data, suggesting the issue is not unique to Chinese manufacturers. 'DupaCycki' adds that the problem is growing with all new cars, especially EVs, due to their advanced connectivity and data collection capabilities.

The community consensus leans toward the idea that Chinese-made EVs, particularly BYD, are highly vulnerable to hacking due to poor cybersecurity practices. However, there is significant pushback against the narrative, with critics arguing that similar vulnerabilities exist in Western cars and that the issue is a broader problem affecting all modern connected vehicles. The debate highlights a deepening concern over data privacy and the potential for mass surveillance by both state and corporate entities.

Key Points

#1BYD EVs can be hacked to access sensitive data and control vehicle functions

A cybersecurity researcher demonstrated that BYD EVs could be hacked to access sensitive data and control vehicle functions with minimal effort, with the microphone used to capture a call where the driver shared internet banking passwords.

#2Chinese EVs are accused of being inherently compromised for surveillance

'Tiral' argues that BYD is a CCP-owned company that blocks the internet and monitors communication, making its EVs inherently compromised for surveillance.

#3Western EVs are not immune to data collection and security risks

'RedWizard' claims that Western brands like Tesla and Toyota also collect vast amounts of data, suggesting the issue is not unique to Chinese manufacturers.

#4The problem is growing with all new cars, especially EVs

'DupaCycki' highlights that the issue is not unique to Chinese EVs but is a growing problem with all new cars, particularly EVs, due to their advanced connectivity and data collection capabilities.

#5Calls for stricter data collection regulations and auditing

'MonkeMischief' argues that there should be a ban on data collection by vehicles and strict auditing to prevent mass surveillance of personal lives by states and corporations.

#6The issue is not limited to Chinese manufacturers

'Cypher' states that both Chinese and US EV manufacturers are equally concerning, as neither country is trustworthy, and both have the ability to compel companies to cooperate with government surveillance.

#7The article is accused of spreading 'sinophobic' claims

'SocialistVibes01' calls the claims 'sinophobic' and accuses the article of spreading 'vegemite rot'.

#8The article is criticized as 'China scary' propaganda

'Jiggle_Physics' argues that the article is 'China scary' propaganda, and other countries' cars also spy on everything, with no significant difference in security risks.
