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.

As of June 2025, the most significant data breach incident in the United States was the Yahoo data breach that dates back to 2013-2016. Impacting over three billion online users, this incident still remains one of the most significant data breaches worldwide. The second-biggest case was the January 2021 data breach at Microsoft, involving about 30 thousand companies in the United States and around 60 thousand companies around the world.

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 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.

Between 2008 and 2024, the most significant data breach in the financial industry worldwide was detected in 2019 in the United States at the First American Financial Corporation. This data breach caused the leakage of *** million financial and personal records. The financial industry is one of the most targeted sectors by cyberattacks that lead to data breaches. However, cyber-attacks are not the only reason for a data breach. Sometimes data compromise occurs due to other reasons, such as system errors.

In 2024, the monetary damage caused by cybercrime reported to the United States' Internet Crime Complaint Center (IC3) saw a year-over-year increase, amounting to a historical peak of **** billion U.S. dollars. Overview of cybercrime in the U.S. Cybercrime continues to be one of the biggest challenges for governments around the world.

As of January 2025, the most significant data breach incident in the United Kingdom (UK) was the 2017-2018 Dixons Carphone breach. As a result of this incident, 14 million user records were affected, and 5.6 million payment card information was exposed. The Equifax data breach between 2011 and 2016 impacted over 15 million customers nationwide.

As of September 2020, almost ** percent of cyber-attacks in the Latin American countries included in the study had targeted users or infrastructures located in Brazil, while approximately ** percent were directed at users in Mexico. Colombia came in third, with over *** percent of cyber-attacks. Greater connectivity, greater vulnerability As internet access and use continues to expand across Latin America, so are the challenges and vulnerabilities regarding cybersecurity. In the first half of 2020, the region recorded the world’s highest cyber-attack rates, with nearly ***** times more attacks via mobile browsers than the global average. While the rapid growth and complexity of network attacks represent a major challenge for the sector, the shortage of trained IT professionals adds a layer of difficulty for organizations in Latin America to tackle these security gaps. Brazil as ground zero for cyber-attacks Among the most emblematic cyber-attacks in recent years are those carried out by hacktivist movement 'Anonymous Brazil' against government sites of the county during the 2016 Summer Olympics in Rio de Janeiro. Although this case drew particular attention given the magnitude of both the event and the attacks delivered, this is far from being an isolated incident in the history of digital strikes to public institutions in Brazil. In fact, in 2019, the Latin American country recorded the highest number of attacks in the region against web apps in the sector. To ensure a safe, reliable, and resilient cyberspace, in February 2020, the Brazilian government implemented its first National Cybersecurity Strategy.

Mobile devices connected to the internet are vulnerable to targeted attacks and security threats. In December 2023, the number of global mobile cyberattacks was approximately 5.4 million, up by 147 percent compared to December 2022. Cyberattacks targeting mobile devices have been decreasing since the end of 2020, after experiencing an annual peak of almost 6.4 million in October 2020. Mobile concerns: Smishing While mobile operating systems come with vulnerabilities requiring patching and regular maintenance, watchful usage can reduce the risk for users of incurring security threats. Smishing attacks are especially reliant on users’ accidental mistakes or naivety. Smishing, or SMS phishing, uses text messages to lure users into accessing fake websites requesting personal data, or into clicking on malicious download links that could infect the device with malware. In the first quarter of 2024, AdWare and RiskTool were the most encountered types of mobile malware worldwide, while Trojan malware accounted for 11 percent of the total. Smishing attacks do not interest regular users alone, but can also target organizations and professionals. In 2023, it was found that the share of IT professionals and organizations targeted by smishing attacks was at 75 percent. Mobile app privacy According to a survey of global consumers carried out in August 2021, both Android and iOS users appeared equally keen to stop using an app if their privacy expectations were not met. Mobile apps have to collect different types of data for functionality purposes, including app diagnostic and device data for location-based services. However, mobile apps also collect other types of more personal user data, such as search history, browsing history, health data, and financial information. The data can be then used by the company that collected them in the first place (1st party data), or with entities that do not have a direct relationship with the users, and obtain data from the main tracking source (3rd party data). Social media apps, like other app categories, rely on acquiring 3rd party data from users for their advertisement business. As of February 2022, TikTok was found to have the highest number of potential 3rd party trackers, followed by Telegram, and Twitter.
