In recent years, healthcare organizations have increasingly become targets of cyberattacks and data breaches, which can lead to serious consequences such as compromised patient data, financial losses, and damage to an organization’s reputation. This article will discuss some of the most common types of healthcare data breaches and provide suggestions for how organizations can protect themselves.
According to a Breach report by U.S. Department of Health and Human Services Office for Civil Rights, out of the 717 healthcare data breaches reported in 2022, 78.6% were due to hacking or IT incidents. Unauthorized access/disclosure accounted for 16%, while theft made up 3.2% of the breaches. These types of incidents have consistently been the most common type of breach, with ransomware attacks being a significant contributor to the rising number of cases each year.
The report also reveals that network server breaches accounted for more than half (57%) of healthcare data breaches in 2022, up from 26.2% in 2019. Breaches through email made up over 23,4%, while paper breaches accounted for approximately 6,5%.
Types of Data and Documents that are Vulnerable to Leaks in Healthcare
Healthcare organizations deal with a wide range of data and documents that are vulnerable to leaks. Some examples of sensitive data include:
-Personal Health Information (PHI)
-Electronic Health Records (EHR)
-Medical billing and insurance information
-Drug prescriptions and usage
-Clinical trial data
Some examples of documents that are vulnerable to leaks include:
-Patient medical records
-Health insurance claims
-Contracts and agreements
How does information leak in the healthcare sector?
One of the most common types of healthcare data breaches is unauthorized access to patient information. This can occur when employees access patient data without a legitimate reason, or when hackers gain access to an organization’s system. In some cases, these breaches can be prevented by implementing strong access controls, such as limiting employee access to sensitive data and requiring multifactor authentication for all logins.
Another common healthcare data breach is the theft of mobile devices. Mobile devices are often used to access patient data, but they can be easily lost or stolen, putting sensitive information at risk. To mitigate this risk, organizations should implement policies and procedures for the secure use of mobile devices, including password protection, encryption, and remote wiping capabilities.
Phishing attacks are another common method used by hackers to gain access to healthcare data. These attacks typically involve sending fraudulent emails or messages that appear to be from a trusted source, such as a hospital or insurance company. To protect against these attacks, organizations should educate their employees about the risks of phishing and provide training on how to identify and avoid these scams.
Finally, ransomware attacks have become increasingly common in the healthcare industry. Ransomware is a type of malware that encrypts an organization’s data and demands payment in exchange for the decryption key. To prevent ransomware attacks, organizations should regularly back up their data and implement strong cybersecurity measures, such as firewalls and intrusion detection systems.
Examples of Document Leaks/Breaches in Healthcare
Document leaks and breaches have occurred in several high-profile cases in the healthcare industry.
Here are some examples:
-Anthem Inc. (2015): The health insurer suffered a data breach that affected over 80 million customers. The breach resulted in the theft of personal information, including names, social security numbers, and medical IDs.
-UCLA Health (2015): A data breach exposed the personal and medical information of 4.5 million patients. The breach was attributed to a cyberattack that compromised the hospital’s network.
-Community Health Systems (2014): Hackers stole the personal data of 4.5 million patients, including names, addresses, and social security numbers. The breach was attributed to a group of Chinese hackers.
Investigation of Healthcare Data Breaches
Healthcare data breaches have been increasing every year, with a significant jump from 329 breaches reported in 2016 to 715 in 2021. Before 2019, there were 500 or fewer breaches reported annually. However, since 2020, the number of reported breaches has exceeded 650 each year. As of January 2023, the reported number of reported healthcare data breaches in from 2022 was nearing 717, with new incidents from the previous year expected to be reported throughout early 2023.
It is also interesting to note that, according to a study, out of the 715 breaches reported in 2021, only 519 (73,5%) have been investigated, with the remaining 196 still under investigation. The situation is even worse for breaches in 2022, where more than 80,8% (580) of all cases are still under investigation.
How to Cope with Leaks of Data in Healthcare
Preventing document leaks and insider threats requires a multi-pronged approach. Healthcare organizations should implement the following measures to reduce the risk of data breaches:
-Employee training and awareness: Healthcare organizations should provide regular training and education to employees on best security practices, including password management, data encryption, and secure document sharing.
-Access control: Healthcare organizations should limit access to sensitive data and documents to authorized personnel only. Access should be granted based on the principle of least privilege.
-Data encryption: Healthcare organizations should encrypt sensitive data and documents to protect them from unauthorized access.
-Secure document sharing: Healthcare organizations should use secure document sharing tools that provide end-to-end encryption and user authentication.
-Monitoring and detection: Healthcare organizations should monitor network activity and implement intrusion detection systems to identify and respond to potential threats.
LeaksID On-Prem Solution for Secure Document Sharing in Healthcare
In addition, LeaksID can be integrated into email, so all attachments sent (including confidential information) will be protected by a special invisible LeaksID marking. This way, each recipient of an email will receive a personalized copy of the document. If someone decides to compromise the document by taking a photo or screenshot and sharing it online, the marking that was added to the personalized document beforehand can be used to determine the source of the leak and who leaked the document. Furthermore, LeaksID can be useful when integrated with a print server, as all documents printed in the company will also be marked to create additional protection. Moreover, LeaksID can help close the majority of unfinished investigations, as its investigation module allows for easy identification of who leaked a document, even with just a photo or fragment of a leaked printed document.
In conclusion, healthcare organizations face a significant threat from cyberattacks and data breaches, which can result in serious consequences such as compromised patient data, financial losses, and damage to an organization’s reputation. The most common types of healthcare data breaches include hacking or IT incidents, unauthorized access/disclosure, and theft. Protecting sensitive data and documents in the healthcare industry requires a multi-pronged approach that includes employee training and awareness, access control, data encryption, secure document sharing, and monitoring and detection. As the number of healthcare data breaches continues to rise, it is essential for organizations to stay vigilant and proactive in their efforts to prevent and respond to these threats.
