Patient Trust on the Line: The Fallout from McLaren Health Care’s 2024 Breach

Daily Security Review

In this episode, we dive into the 2024 McLaren Health Care data breach that compromised the sensitive information of over 743,000 individuals—just one year after a similar ransomware attack impacted 2.2 million.

We’ll unpack the timeline of the attack: how cybercriminals gained unauthorized access between July 17 and August 3, exploiting vulnerabilities in McLaren’s network to steal personally identifiable information (PII) and protected health information (PHI)—including Social Security numbers and medical records.

But this is about more than one hospital system. We’ll explore why the healthcare sector has become a prime target for ransomware: a dangerous blend of valuable data, critical infrastructure, underfunded IT security, and human factors.
You'll hear why hospitals are often willing to pay ransoms to keep life-saving services online, and how this creates a vicious cycle for attackers to exploit.

We’ll also cover broader insights from EU and US sources, including:

• The prevalence of ransomware in healthcare — 54% of all attacks in recent years
• The systemic vulnerabilities — from outdated IT and legacy systems to insufficient staff training and third-party risks
• The impact on patient trust and care delivery — including delayed treatments and fear around sharing health details
• Why robust cybersecurity measures, Zero Trust Architecture, and regular employee training are critical mitigation strategies

Finally, we’ll discuss what patients can do if their data is compromised — from understanding credit monitoring’s limits to knowing their legal rights and potential for class action.

Whether you're in healthcare, cybersecurity, or simply concerned about data privacy, this episode offers a timely look at how ransomware is reshaping the healthcare landscape—and what must be done to fight back.
