Cyber News Centre's cyber update for 24th September 2025: Automotive giant Stellantis has confirmed a significant data breach after a third-party service provider was compromised, exposing the contact information of its North American customers.

Stellantis is the world’s fifth-largest carmaker, created in 2021 through the merger of Fiat Chrysler Automobiles and PSA Group. Its brand portfolio includes Jeep, Dodge, Ram, Chrysler, Fiat, Peugeot, and Alfa Romeo, with operations spanning more than 130 countries.

The Update and Why It Matters

The Update: Stellantis confirmed over the weekend that it detected unauthorised access to a third-party service provider’s platform supporting its North American customer service operations. The cybercriminal group known as ShinyHunters has claimed responsibility, alleging it stole 18 million customer records from the company’s Salesforce system.

The compromised data is limited to contact information, such as names, email addresses, and phone numbers. The company said no financial or other sensitive personal data was accessed. In a statement, Stellantis confirmed,

"Upon discovery, we immediately activated our incident response protocols ... and are directly informing affected customers. The incident, which is under investigation, exposed only basic contact information and did not involve financial details or sensitive personal data."

The attack is part of a broader campaign by ShinyHunters targeting organisations that use Salesforce, relying on voice phishing tactics to gain initial access by impersonating IT support staff and tricking employees into granting malicious OAuth application access.

Why it matters: This breach highlights the serious and ongoing risk of supply chain attacks, where a weakness in a single vendor can compromise the data of a global corporation. The incident at Stellantis is not isolated but part of a growing pattern of attacks against enterprise SaaS platforms, as security experts have noted.

It is a stark reminder of how interconnected global data systems are, information held by international companies can be compromised anywhere in the world. The Australian Cyber Security Centre (ACSC) has specifically warned about rising risks linked to connected vehicles. This breach reinforces the threat of customer data exposure, raising the likelihood of targeted phishing and social engineering campaigns aimed at vehicle owners.
