Facebook Fined €251 Million for 2018 Data Breach Affecting 29 Million Users

2024-12-17

In a significant ruling, the Irish Data Protection Commission (DPC) has imposed a €251 million fine on Meta Platforms Ireland Limited for a 2018 data breach that impacted approximately 29 million Facebook accounts worldwide. This decision follows two inquiries launched by the DPC after Meta reported the breach in September 2018.

The breach exploited a vulnerability in the “View As” feature, allowing hackers to steal Facebook access tokens of unsuspecting users. By exploiting this flaw, attackers gained access to a wealth of personal information, including user names, phone numbers, email addresses, profile details (gender, relationship status, etc.), and even posts on timelines and group memberships.

The DPC found Meta in violation of the General Data Protection Regulation (GDPR) in several areas, including insufficient breach notifications, poor breach documentation, design flaws, and a failure to implement appropriate data protection measures by default.

The DPC emphasized the significant risks posed by the breach, highlighting that Facebook profiles often contain sensitive personal information that users may not wish to share publicly. The unauthorized exposure of this data created a grave risk of misuse, impacting the fundamental rights and freedoms of individuals.

This hefty fine serves as a strong reminder to companies of their obligations under the GDPR to prioritize data security and implement robust measures to protect user data.

What Undercode Says:

This case underscores several critical aspects of data protection and cybersecurity:

The Importance of Proactive Security: The breach stemmed from a vulnerability in the “View As” feature, highlighting the importance of rigorous security assessments and penetration testing throughout the development lifecycle. Meta should have proactively identified and addressed this vulnerability before it could be exploited by malicious actors.
The Value of Privacy-by-Design: The GDPR emphasizes the principle of “privacy-by-design,” which requires data protection considerations to be integrated into the design and development of systems and services from the outset. This case demonstrates the severe consequences of failing to adhere to this principle.
The Impact of Data Breaches: The unauthorized access to personal information can have serious repercussions for individuals, including identity theft, financial fraud, and reputational damage. Companies must take all necessary steps to prevent data breaches and minimize the impact of such incidents when they occur.
The Role of Regulation: The significant fine imposed by the DPC demonstrates the seriousness with which regulators view data protection violations. Companies must comply with the GDPR and other relevant regulations to avoid facing hefty penalties and reputational damage.

This case serves as a valuable lesson for all organizations, emphasizing the critical importance of robust data security measures, a proactive approach to cybersecurity, and a commitment to user privacy.
