The healthcare sector has become a prime target for cybercriminals, leading to significant breaches of the Health Insurance Portability and Accountability Act (HIPAA). The increasing reliance on digital systems, coupled with the vast amounts of sensitive patient data, makes healthcare organizations attractive targets for cyber threats. Understanding the common types of HIPAA breaches and ransomware attacks is crucial for healthcare organizations aiming to safeguard patient data, maintain compliance, and protect their reputations.
Common Types of HIPAA Breaches: Hacking & IT Incidents
Hacking and IT incidents occur when cybercriminals exploit weaknesses in healthcare systems to gain unauthorized access to protected health information (PHI). These breaches often stem from outdated security protocols, unpatched software vulnerabilities, or inadequate network defenses. Attackers use tactics such as phishing, malware, and ransomware to infiltrate healthcare networks, compromising sensitive patient data. Without robust cybersecurity measures in place, healthcare organizations become prime targets for these breaches, leading to significant financial and reputational damage.
In November 2023, Ardent Health Services, a healthcare provider operating 30 hospitals across six states, was hit by a ransomware attack that caused widespread disruption across its network. The attack, discovered on Thanksgiving Day (November 23), forced Ardent to proactively shut down its IT systems, impacting access to corporate servers, Epic electronic health records (EHR), internet services, and various clinical programs.
The incident had immediate and significant operational consequences:
- Emergency Room Diversions: Several hospitals had to divert incoming ambulance traffic to nearby facilities due to system outages.
- Rescheduling of Procedures: Numerous non-emergency procedures were postponed while critical systems were brought back online.
Despite the disruption, Ardent maintained safe, manual delivery of patient care across hospitals, emergency rooms, and outpatient settings.
To respond to the crisis, Ardent initiated a comprehensive incident response that included:
- Notification of Law Enforcement: Federal agencies were promptly informed.
- Engagement of Cybersecurity Experts: Third-party forensic specialists and threat intelligence teams were brought in to investigate and assist with recovery.
- Deployment of Enhanced Security Protocols: Additional safeguards were implemented to restore systems securely and prevent further intrusion.
By December 6, 2023, Ardent had successfully restored access to its Epic EHR system and resumed most clinical operations. Emergency rooms were again accepting patients by ambulance, and outpatient clinics reopened. Some elective procedures remained temporarily delayed pending full system restoration.
Later disclosures revealed that over 300,000 patients’ personal data may have been compromised during the attack. This led to a class-action lawsuit, alleging that Ardent failed to implement adequate cybersecurity measures to protect sensitive health information.
This breach underscores the severe and growing risk ransomware poses to the healthcare sector. It also highlights the need for proactive vulnerability management, secure EHR infrastructure, and well-coordinated incident response planning to mitigate operational and regulatory fallout.
Unauthorized Access or Disclosure
Unauthorized access or disclosure occurs when employees or third parties view, share, or misuse PHI without proper authorization. This can happen due to curiosity, financial motives, or unintentional errors, such as sending patient records to the wrong recipient. Weak internal controls, lack of role-based access restrictions, and insufficient auditing contribute to these breaches, which can lead to regulatory fines, legal consequences, and loss of patient trust.
In a notable 2024 case, a hospital employee accessed the medical records of 1,200 patients without authorization over a period of several months. The breach was discovered during an internal audit when irregular access patterns were flagged. An investigation revealed that the employee had been viewing patient records without a legitimate work-related reason, violating HIPAA regulations. The hospital faced legal action and reputational damage, ultimately strengthening its security policies by implementing stricter access controls, automated audit logs, and enhanced employee training to prevent future incidents.
Loss or Theft of Devices
Unencrypted devices containing PHI, such as laptops, smartphones, or USB drives, can lead to breaches if lost or stolen. Mobile healthcare workers and remote employees are particularly at risk, as they often carry devices outside secure office environments. If these devices lack proper encryption or remote-wipe capabilities, unauthorized individuals can access sensitive patient data, leading to compliance violations and identity theft.
A recent breach in 2024 involved a lost laptop containing sensitive patient information, affecting nearly 50,000 individuals. A thief stole a healthcare administrator’s unencrypted laptop from a parked vehicle and gained access to the stored patient records. The breach led to legal action and regulatory penalties for failing to implement adequate security measures. In response, the organization revised its policies, mandating full-disk encryption for all portable devices and requiring multi-factor authentication (MFA) for data access.
Improper Disposal
Failing to securely dispose of documents or devices containing PHI can result in unauthorized access, potentially leading to identity theft, fraud, or regulatory penalties. Healthcare organizations generate vast amounts of sensitive patient data, making secure disposal a critical aspect of compliance. Organizations must shred paper records and thoroughly wipe or physically destroy electronic devices before disposal to prevent unauthorized data retrieval.
In one case, a clinic improperly discarded old patient files in a public dumpster, allowing unauthorized individuals to access sensitive medical information. This oversight led to an investigation by the Department of Health and Human Services (HHS) and substantial HIPAA violation fines. The clinic implemented stricter disposal policies, trained employees on proper data destruction methods, and began conducting routine audits to ensure ongoing compliance.
Ransomware Attacks in Healthcare
Ransomware attacks involve malicious software that encrypts networks, rendering them inoperable until a ransom is paid. Attackers often gain access through phishing emails, compromised credentials, or exploiting unpatched vulnerabilities in outdated software. Once inside, the ransomware spreads laterally across the network, locking patient records, appointment schedules, and even critical medical devices connected to the system. The healthcare industry has seen a surge in these attacks due to the high value of medical data and the urgent need for hospitals to restore operations quickly, making them more likely to pay ransoms. The U.S. Office of the Director of National Intelligence reported a 128% increase in attacks against the U.S. healthcare sector, with 258 incidents in 2023 compared to 113 in 2022.
Notable Incidents
In 2024, a ransomware attack targeted a major hospital network, encrypting over 914,000 patient records. A sophisticated threat actor group launched the attack by sending a phishing email with a malicious attachment. Once an employee opened it, the group exploited unpatched vulnerabilities in the hospital’s outdated IT infrastructure to infiltrate and gain access to sensitive systems. Upon infiltration, the attackers deployed the ransomware, which encrypted critical medical records, including patient histories, diagnoses, and ongoing treatments.
The attack caused significant disruption across the hospital’s network, severely affecting daily operations. Staff delayed or rescheduled surgeries and struggled to provide quality care without access to essential patient records. The hospital’s emergency department quickly became overwhelmed as the cyberattack disabled critical systems, including scheduling and patient tracking, leaving teams without the tools needed to manage patient flow effectively.
Overwhelmed by the scale of the cyberattack and unable to restore systems quickly, hospital leadership made the difficult decision to negotiate directly with the attackers. After weeks of halted operations and mounting internal and external pressure, the hospital paid a multi-million-dollar ransom in cryptocurrency to regain access to its encrypted data. However, the payment didn’t result in the immediate return of full functionality. The hospital faced a prolonged recovery period, during which teams manually restored many systems and gradually decrypted sensitive data.
This incident highlighted the devastating financial and operational impact of ransomware attacks on critical healthcare systems. It also served as a stark reminder of the importance of robust cybersecurity measures, including timely software updates, employee training on phishing threats, and having a comprehensive incident response plan in place. The hospital has since implemented stricter security protocols, including enhanced encryption methods, multi-factor authentication, and greater collaboration with external cybersecurity experts to prevent future attacks.
