Introduction

In today’s world of advanced technology and interconnectedness, data breaches have become a significant concern for individuals and organizations alike. With millions of people’s sensitive information compromised each year, the impact of these breaches can be devastating.

The US Health and Human Services (HHS) maintains a public list of healthcare data breaches called the “Wall of Shame.” This list was created as part of the Health Insurance Portability and Accountability Act (HIPAA) to promote the protection of patient privacy and their protected health information (PHI). The Breach Notification Portal is the official name of this list, and it includes reported breaches affecting 500 or more individuals. Covered entities (CEs) and their business associates (BAs) must follow HIPAA guidelines to reduce the risk of a breach and avoid being listed on the Wall of Shame. The information on the Wall of Shame includes the CE’s name, state of residence, type of CE, number of affected individuals, breach submission date, type of breach, and location of the breach. The data from the Wall of Shame can be used to combat data breaches, identify insider mistakes or outside threats, and provide evidence about threat actors and their common vectors of attack to help IT officials combat future attacks.

Indiana still ranks the highest in terms of average number of affected individuals per breach, which can be largely attributed to the massive Anthem breach. Florida, however, has dropped down to 9th, indicating that it may not be as bad as initially thought. Virginia had a lower total number of affected individuals, but a higher average per breach, which suggests that some states may experience more frequent breaches, while others may be more susceptible to larger-scale breaches.

Average affected by Industry

Covered Entity Type total_affected
Health Plan 430357.68
Business Associate 59113.34
Healthcare Provider 17469.74
Healthcare Clearing House 4438.50

The table provides a breakdown of the number of affected individuals by the type of entity responsible for the data breaches. Health plans appear to be the highest offenders, with an average of over 430,000 individuals affected per breach. Business associates are the second highest on the list with an average of over 59,000 individuals affected per breach, followed by healthcare providers with an average of around 17,500 individuals affected per breach. It is surprising to note that healthcare providers are not the highest offenders in this list, considering their access to sensitive patient information. It is interesting to see the contrast between business associates and healthcare providers and their average number of breaches. These results suggest the need for improved data security measures across all types of entities that handle sensitive information.

Busniuss Accociates Leaking the Data

While data breaches continue to be a major concern for both individuals and businesses alike, it’s important to identify the sources of these breaches in order to prevent them from happening in the future. In this next data table, we’ll be looking at the top Business Associates that have been responsible for leaking data, so we can gain a better understanding of where our data might be at risk.

State Name of Covered Entity Covered Entity Type Individuals Affected
VA Science Applications International Corporation (SA Business Associate 4900000
TX Xerox State Healthcare, LLC Business Associate 2000000
NY IBM Business Associate 1900000
NJ GRM Information Management Services Business Associate 1700000
NJ Horizon Healthcare Services, Inc., doing business as Horizon Blue Cross Blue Shield of New Jersey, and its affiliates Business Associate 839711
PA Iron Mountain Data Products, Inc. (now known as Business Associate 800000
UT Utah Department of Technology Services Business Associate 780000
NJ Sutherland Healthcare Solutions, Inc.  Business Associate 342197
TX Shred-it International Inc.  Business Associate 277014
TX Digital Archive Management Business Associate 189489

The table provides information on the top 10 business associates that have experienced data breaches affecting a large number of individuals. Science Applications International Corporation (SA), Xerox State Healthcare, LLC, and IBM are the top three on the list, with SA being the most affected entity, affecting 4.9 million individuals in Virginia. It is concerning to note that the breach has affected such a large number of individuals, potentially compromising their personal information. The fact that these large, reputable companies were breached underscores the importance of cybersecurity measures in today’s increasingly digital world.

Interestingly, the ninth entity on the list is Shred-it International Inc., which is a company that specializes in secure document destruction. It is surprising to see that a company specializing in data security had a data breach. However, after looking into the particular incident, there is no further information to explain the cause of their breach.

##In which year (or years) were there at least 50 breaches from a ‘Business Associate’ covered entity type and at least 150 breaches from a healthcare provider covered entity type?

Year1 Business Associate Breaches Health Care Breaches
2013 64 187
2014 67 179

The table provides data on healthcare data breaches for two consecutive years, 2013 and 2014. The data is divided into two categories: Business Associate Breaches and Health Care Breaches.

According to the data, there were 64 reported Business Associate Breaches in 2013 and 67 in 2014. Meanwhile, there were 187 reported Health Care Breaches in 2013 and 179 in 2014.

The data suggests that while the number of reported Business Associate Breaches increased slightly from 2013 to 2014, the number of reported Health Care Breaches decreased over the same period.

How has the type of breach (hacking, improper disposal, loss, etc.) changed for each year?

Year Theft Improper disposal Loss Hacking Unauthorized Access/Disclosure Unknown Other
2009 15 0 1 0 0 0 2
2010 135 10 20 8 10 0 23
2011 122 7 18 17 34 7 2
2012 124 8 20 17 40 2 20
2013 131 13 24 27 73 3 19
2014 111 11 30 37 98 1 28
2015 64 6 23 25 80 0 0
2016 46 7 12 71 96 0 0
2017 17 4 9 32 43 0 0
2018 0 0 0 0 1 0 0

The data indicates that the number of security incidents reported increased over time until 2014, after which there was a sharp decline. The most common types of security incidents reported were Unauthorized Access/Disclosure and Hacking. However, there were a significant number of incidents classified as “Unknown” or “Other,” suggesting the need for improvement in the organization’s reporting and tracking processes. It is also important to note that there were no reported incidents in 2018, but it is possible that there were unreported incidents. Overall, the table highlights the importance of maintaining good security practices and processes to minimize security incidents and protect sensitive information.

Visuals

Number of healthcare data breaches by year

The graph provides a visual representation of the number of individuals affected by healthcare breaches over time. It is clear from the graph that there are two peaks in the number of individuals affected, occurring in the years 2013-2014. This highlights the significance of breaches that occurred during these years, potentially affecting a large number of individuals and causing significant harm.

Total healthcare records (individuals affected) exposed by state for the top 10 states

The data presented in the graph shows the average number of individuals affected by healthcare breaches in each state. Interestingly, Indiana has the highest average number of individuals affected, suggesting that there have been significant breaches in the state. It is worth noting that this average is heavily influenced by a single incident involving Anthem, which affected over 78 million individuals in 2015. If we removed Anthem from the dataset, it is likely that the average for Indiana would be closer to the averages of other states.

However, even without the Anthem breach, Virginia emerges as the runner-up with the second-highest average number of individuals affected by healthcare breaches. This highlights the importance of data security in the healthcare industry, particularly in states with large populations and high concentrations of healthcare organizations.

Number of healthcare hacking incidents by month

The graph provides insight into the frequency of healthcare data breaches by month. September and May are the two months with the highest number of breaches, while the other months are relatively consistent in terms of the number of breaches reported.

However, it is important to note that the number of breaches reported each month may be influenced by a range of factors, including reporting cycles, security measures in place, and other external factors. Therefore, it is difficult to draw definitive conclusions about trends based solely on the number of breaches reported in a given month.

That being said, if we were to take the average number of breaches reported across all months, it appears to be around 20 attacks in a week. This underscores the ongoing threat that healthcare organizations face from data breaches and the importance of robust data security measures to protect patient information.

On what day of the week (Sunday, Monday, etc.) are breaches most often reported?

The graph provides insight into the frequency of healthcare data breaches reported by day of the week. According to the data, Fridays have the highest number of reported breaches, while Saturday and Sunday have the fewest. This trend may be due to a range of factors, including differences in reporting cycles or the timing of attacks.

However, it is also worth noting that the number of reported breaches may be influenced by factors such as when the organization chooses to report the breach, rather than the actual timing of the attack. It is possible that organizations may be more likely to report breaches on a Friday as it is the end of the workweek and may be seen as a natural reporting deadline.

Another interesting trend is that Monday through Thursday have a relatively even distribution of reported breaches, with nearly 300 attacks reported each day. This highlights the ongoing threat that healthcare organizations face from data breaches and the need for robust data security measures to protect patient information.

When there was a Business Associate Present was the Individuals Affected Higher or lower?

This indicates that when a business associate is present during the breach, there tends to be an average difference of 24,000 affected individuals compared to when a business associate is not present.

Does the type of breach have an impact on how many individuals are affected?

The chart being discussed displays the impact of different types of breaches on the number of individuals affected. It is noted that “hacking” has the highest impact in terms of the scale of the breach, with an average of nearly 400,000 individuals affected. This suggests that hacking is a particularly potent type of breach, with the potential to expose large amounts of sensitive data to unauthorized individuals or groups.

The chart also shows that the next highest impact type of breach is labeled as “unknown.” This raises questions and possibilities, such as investigating whether these “unknown” breaches are also a result of hacking or some other type of breach. Understanding the nature of these unknown breaches could help organizations better protect themselves and their customers against future data breaches.

It is further noted that all other types of breaches on the chart are on a lower scale than hacking, with the third largest type of breach being labeled as “Loss” and affecting almost 60,000 individuals on average. This suggests that while there are other types of breaches that can have significant impacts, none of them come close to the scale of hacking in terms of the number of individuals affected.

Conclusion

In conclusion, data breaches have become a significant concern for individuals and organizations in today’s interconnected world. The US Health and Human Services (HHS) maintains a public list of healthcare data breaches called the “Wall of Shame” as part of the Health Insurance Portability and Accountability Act (HIPAA) to promote the protection of patient privacy and their protected health information (PHI). By analyzing the breach data, it becomes clear that data breaches can have a devastating impact on organizations and individuals. The tables in this paper highlight the top states and covered entities affected by data breaches and the importance of maintaining data privacy and implementing strong security measures to prevent data breaches. Furthermore, the data highlights the need for improved data security measures across all types of entities that handle sensitive information, including business associates, who are responsible for a significant number of data breaches. By identifying the sources of data breaches, organizations can take steps to prevent them from happening in the future, thus reducing the risk of sensitive information being compromised.
