The Cyber Security Breaches Survey, 2020 was run to understand organisations' approaches and attitudes to cyber security, and to understand their experience of cyber security breaches. Its aim was to support the Government by providing evidence that can inform policies which help to make Britain a safer place to do business online.

The data have been collected annually since 2016 to understand the views of UK organisations on cyber security. Data is collected on topics including online use; attitudes of organisations to cyber security and awareness of Government initiatives; approaches to cyber security (including investment and processes); incidences and impact of a cyber security breach or attack; and how breaches are dealt with by the organisation. This information helps to inform Government policy towards organisations, including how best to target key messages to businesses and charities so that they are cyber secure (and so that the UK is the safest place in the world to do business online). The study is funded by the Cabinet Office as part of the National Cyber Security Programme.

The underlying data are useful for researchers to better understand the response across a range of organisations (rather than averages) and for wider comparability over time. The survey originally only covered businesses but was expanded to include charities from the 2018 survey onwards. From 2020, the survey includes a sample of education institutions (primary and secondary schools, further and higher education). Please note that the UK Data Service only holds data from 2018 onwards.

Washington law requires entities impacted by a data breach to notify the Attorney General’s Office (AGO) when more than 500 Washingtonians personal information was compromised as a result of the breach. This dataset breaks out the individual types of breached personal information that were identified in each notice our office received. This data is used to produce the AGO’s Annual Data Breach Report. For additional statistics relating to data breaches, also see the main dataset at: https://data.wa.gov/Consumer-Protection/Data-Breach-Notifications-Affecting-Washington-Res/sb4j-ca4h.

Between January 18 and November 2023, a quarter of data breach incidents in the United States government happened at city administration offices. A further 17 percent of the incidents involved counties, while law enforcement agencies encountered 14 percent of the data breaches.

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.

Between January and November 2023, around six million data records were affected in online data breaches recorded in government entities in Louisiana, making it the U.S. state with the highest number of breached data records in government. In the measured period, the state of Colorado's government agencies and public administration offices saw the exposure of nearly 4.2 million data records. Overall, 2.24 billion data records were affected by government data breaches in the United States in the measured period.
