In response, and stakeholders are being briefed through Public disclosure (delayed; breach occurred in May 2023, announced later).

The case underscores how teams are taking away lessons such as Delayed breach disclosure can amplify risks (e.g., prolonged exposure to scams). Customers should freeze credit and scrutinize unsolicited communications referencing personal/vehicle details, and recommending next steps like Customers: Freeze credit reports to prevent loan fraud, verify sender authenticity before clicking links/sharing data, monitor for phishing attempts referencing vehicle ownership and Stellantis: Improve breach detection/response timelines, enhance customer communication strategies, and implement proactive fraud monitoring for affected individuals, with advisories going out to stakeholders covering Warnings issued about phishing risks leveraging vehicle ownership data.
