Cyber risks of connected company vehicles

In the digital age, cars have become more than just means of transportation. Modern, internet-connected company cars offer convenience, efficiency and control, but with that comes new cyber risks. This article explains how corporate fleets are transforming into digital ecosystems, what threats they face, and what measures companies should take to protect both data and the vehicles themselves.

Connected Cars: What it means

Interconnected or connected vehicles communicate with external networks via cellular, Wi-Fi or satellite connections. They enable:

Remote monitoring and diagnostics,
Over-The-Air (OTA) software updates,
integration with fleet systems,
interfacing with mobile applications,
sharing of location, speed and driving data.

These features improve fleet operations and efficiency, but also pose a significant risk in the event of misuse.

The main cyber threats to corporate fleets

1. Unauthorised vehicle access

Hackers may attempt to penetrate a vehicle's system via Bluetooth, Wi-Fi or cellular connection to gain control of its functions (e.g. lock, engine, GPS).

2. Theft or data leakage

Connected systems collect drivers' personal data, routes, fuel consumption and service records. This data is a frequent target of cyber-attackers.

3. Software manipulation

Unauthorized updates or malware can affect vehicle systems, from infotainment to engine management.

4. Phishing and social attacks on drivers

Cybercriminals often target drivers via fake SMS or emails that look like messages from the fleet provider.

5. Disruption of fleet networks

Hitting a central system can bring corporate mobility to a complete halt.

Protecting your fleet: How to minimise the risks

1. Regular software updates

Always install official updates from the committee or rental providers such as Payless.

2. Centralised access control

Implement single sign-on (SSO) and multi-level authentication for both drivers and administrators.

3. Segment fleet networks

Separating infotainment systems from operational functions minimizes intrusion into critical parts of the vehicle.

4. Cyber training for drivers

Ensure employees recognize fraudulent emails, fake apps, and risky behaviors.

5. Collaborate with certified partners

With a provider like Payless Lease, your business gets vehicles maintained in accordance with current cybersecurity standards.

Trends in corporate vehicle cybersecurity

Artificial Intelligence (AI): systems learn to recognize anomalies in vehicle behavior.
Blockchain: protecting the links in the communication chain.
End-to-end encryption: another layer of protection for data transmitted between the vehicle and the cloud.
UNECE Regulation R155: from June 2024, new vehicle models must have certified cybersecurity systems.

Cybersecurity as an asset

Cyber protection is not just an expense, but an investment in credibility and business continuity. Loss of client trust, business interruption or fines for data leaks can cost a company more than prevention alone.

For example: according to IBM's Cost of a Data Breach 2025survey , the average loss from a cyber-attack in the automotive sector is more than $4.5 million. USD.

Frequently Asked Questions (FAQ)

1. How can a hacker attack a vehicle?
Via Wi-Fi, Bluetooth or a weak connection to a cellular network if the system is not updated.

2. Who is responsible for protecting the data in the company car?
The owner or operator of the fleet - for example, the leasing company and the company itself.

3. Will an antivirus or VPN in the vehicle help?
Often these are implemented directly in the system, but it is important to use certified solutions from experts.

4. Can the company car be disconnected from the internet?
It can, but many functions will be lost (monitoring, OTA updates, diagnostics).

5. What standards must cars meet by 2024?
UNECE R155 and R156 set mandatory cybersecurity and software requirements.

TL;DR / Summary

Connected cars bring both comfort and risk.
Cybersecurity is the new pillar of corporate mobility.
Investment in data protection pays back in the form of trust.
Companies should choose partners like Payless Lease with guaranteed IT security.
Vehicle protection = reputation protection.
