Top 50 Healthcare Security Breaches of All Time

Once you understand the catastrophic impact of healthcare cybercrime, you might start to worry about your own healthcare security risks. If not, you should.

News of medical data cyberattacks keeps on coming. From January to May of this year, we have seen an average of 29 significant events per month.

What is a Healthcare Data Breach

A data breach allows unauthorized persons — usually criminals — to access files that are stored on health service providers’ computer systems. Those records can include any or all of the following:

  • patient’s name, address, and email address
  • banking and payment method information
  • Social Security numbers
  • medical history, including information on procedures
  • medical images
  • prescription history
  • insurance information
  • drug-testing results
  • medical staff certification and employment information
  • spousal and dependant information
  • emergency contact information

Exploring how widespread the problem is will be the focus of this special article.

The Cost of Healthcare Cyber Security Attacks

Security breaches in healthcare systems is nothing new. But that doesn’t make them any less costly.

2018 has already seen a 16.4% increase in the cost of healthcare data security breaches compared to last year. The average cost per attack? $3.86 million.

Healthcare information security is becoming a hot topic for consumers. A healthcare security report indicated that 38% of those surveyed are concerned about the security of their medical records. If you are among them, our research will do nothing to reduce your fears.

In this article, we have compiled a list of some of the top healthcare information security breaches of all time.

Not surprisingly, few companies included in our list claim that wrongdoing on their part contributed to their patients’ data being compromised. And they may be right. One thing they all agree on is the need for better protection mechanisms securing our medical data.

Top 50 Healthcare Security Breaches of All Time

1. HealthEquity

HealthEquity reported in April that 23,000 of its accounts had been compromised.

The breach resulted from a successful email phishing attack, which allowed the hacker to access company emails.

While the affected files did not contain medical data, other sensitive information was available to the hacker. The names of company employees, Social Security numbers of employees, member IDs, deduction amounts, and account details were compromised.

2. Medicaid (Florida)

In November, a massive hack compromised 30,000 non-medical records for Medicaid patients in Florida.

The healthcare security breach was traced to a phishing email received — and acted upon — by an employee.

3. BJC HealthCare

In January, a misconfigured BJC HealthCare server made 33,420 patients’ records accessible without protection on the Internet.

There was no indication that any Protected Health Information (PHI) data was accessed, but a healthcare security services investigation could not rule it out.

4. ATI Physical Therapy

In January of this year, ATI Physical Therapy discovered a security breach that possibly compromised the records of more than 35,000 patients.

By accessing employee email accounts, the attacker changed employee direct deposit information. Further investigation revealed the hacker also accessed tens of thousands of emails containing patient PHI data.

5. Holland Eye Surgery & Laser Center

In March of this year, Holland Eye Surgery & Laser Center saw something bad. A breach in their network had allowed a hacker access since June of 2016.

The University of California, Los Angeles Health System (UCLA) is no small potato. The institution is one of the largest and most well-respected healthcare providers in the U.S. Even so, they fell prey to hackers in 2015, when a hacker accessed a major database.

An investigation revealed that the perpetrator spent a year probing the system. In 2015, they hit paydirt. A database containing PHI data of 4.5 million patients and staff was copied.


Even the medical records of military personnel are not immune from healthcare data breaches. Science Applications International Corp., a vendor for Tricare Management Activity insurance company, had backup tapes of patient data stolen in September of 2011.

50. LabCorp’s

Headquartered in Burlington, North Carolina, the mammoth medical testing provider

LabCorp was targeted by ransomware on July 14th of this year.

115 million patient records were potentially compromised. Hackers accessed data by breaching the company’s network security.

What the LabCorp Data Breach Means

Labcorp may — for now — have the unfortunate distinction as the company with the greatest number of files potentially exposed during a single data breach. This does not suggest they did not have solid data security in place.

You bet they did.

What LabCorp’s cyberattack means to the healthcare industry raises a far more important question: If one of the world’s largest and most responsible healthcare service providers can fall victim to cybercrime, what does that mean for the future of the healthcare industry?

The answer lies in AI-based protection mechanisms that nestle data within robust blockchains. If LabCorp’s hack leads the industry to adopt such solutions, then maybe it will mark the turning point in the war on cybercrime.
