The largest reported data leakage as of January 2025 was the Cam4 data breach in March 2020, which exposed more than 10 billion data records. The second-largest data breach in history so far, the Yahoo data breach, occurred in 2013. The company initially reported about one billion exposed data records, but after an investigation, the company updated the number, revealing that three billion accounts were affected. The National Public Data Breach was announced in August 2024. The incident became public when personally identifiable information of individuals became available for sale on the dark web. Overall, the security professionals estimate the leakage of nearly three billion personal records. The next significant data leakage was the March 2018 security breach of India's national ID database, Aadhaar, with over 1.1 billion records exposed. This included biometric information such as identification numbers and fingerprint scans, which could be used to open bank accounts and receive financial aid, among other government services.

Cybercrime - the dark side of digitalization As the world continues its journey into the digital age, corporations and governments across the globe have been increasing their reliance on technology to collect, analyze and store personal data. This, in turn, has led to a rise in the number of cyber crimes, ranging from minor breaches to global-scale attacks impacting billions of users – such as in the case of Yahoo. Within the U.S. alone, 1802 cases of data compromise were reported in 2022. This was a marked increase from the 447 cases reported a decade prior. The high price of data protection As of 2022, the average cost of a single data breach across all industries worldwide stood at around 4.35 million U.S. dollars. This was found to be most costly in the healthcare sector, with each leak reported to have cost the affected party a hefty 10.1 million U.S. dollars. The financial segment followed closely behind. Here, each breach resulted in a loss of approximately 6 million U.S. dollars - 1.5 million more than the global average.

In 2024, the number of data compromises in the United States stood at 3,158 cases. Meanwhile, over 1.35 billion individuals were affected in the same year by data compromises, including data breaches, leakage, and exposure. While these are three different events, they have one thing in common. As a result of all three incidents, the sensitive data is accessed by an unauthorized threat actor. Industries most vulnerable to data breaches Some industry sectors usually see more significant cases of private data violations than others. This is determined by the type and volume of the personal information organizations of these sectors store. In 2024 the financial services, healthcare, and professional services were the three industry sectors that recorded most data breaches. Overall, the number of healthcare data breaches in some industry sectors in the United States has gradually increased within the past few years. However, some sectors saw decrease. Largest data exposures worldwide In 2020, an adult streaming website, CAM4, experienced a leakage of nearly 11 billion records. This, by far, is the most extensive reported data leakage. This case, though, is unique because cyber security researchers found the vulnerability before the cyber criminals. The second-largest data breach is the Yahoo data breach, dating back to 2013. The company first reported about one billion exposed records, then later, in 2017, came up with an updated number of leaked records, which was three billion. In March 2018, the third biggest data breach happened, involving India’s national identification database Aadhaar. As a result of this incident, over 1.1 billion records were exposed.

As of January 2025, the most significant data privacy violation fine worldwide was for social media giant Meta. In May 2023, the Data Protection Commission (DPC) of Ireland decided to fine the company with 1.2 billion euros or 1.3 billion U.S. dollars. The Chinese vehicle-for rent company Didi Global ranked second. In July 2022, China's data privacy regulator fined the company 8.026 billion Chinese yuan, or 1.19 billion U.S. dollars. The 2021 Amazon fine issued by Luxembourg's data privacy regulation authorities was 877 million U.S. dollars and was the third-biggest data breach fine as of the measured month. The 2019 fine of 575 million U.S. dollars to Equifax followed. In this incident, because of unpatched vulnerabilities, nearly 150 million people were affected, which caused the American consumer credit reporting agency to pay at least 575 million U.S. dollars.

A survey carried out in 2021 revealed how important having more control over personal data is to adults in the United States. A third of respondents said this was extremely important to them, another third said it was very important, and roughly ** percent said it was moderately important. Just *** percent said having more control over personal data and how it is shared was not at all important to them. Most Americans worry about falling victim to cybercrime When asked in a 2020 survey to name crimes they were most afraid of, the majority of American respondents claimed to be more worried about cybercrimes than having their home broken into or car stolen. The top two concerns were having personal financial information stolen by hackers, and being the victim of identity theft. This is unsurprising, considering the rise in data breaches and exposed records over the past decade. In the United States alone, *** billion data breaches were reported in 2017 - the highest figure to date. It is likely that this figure was somewhat impacted by the infamous Yahoo! data breach scandal that year, where * billion user accounts worldwide were compromised. This has been recognized as one of the largest breaches of its kind in history. IT security market on the rise As a direct result of increasing security demands and rising concerns, more companies than ever before are investing in cyber security, both in the form of services and technology. The information security technology market is booming, and as a result worldwide spend is predicted to hit nearly *** billion U.S. dollars by 2024, a ** billion dollar increase from one year prior.
