Mclaren Health Care says data breach impacted 2.2 million people

Mclaren Health Care (Mclaren) has notified nearly 2.2 million individuals of a data breach that occurred between late July and August of this year. The breach resulted in the exposure of sensitive personal information.

About Mclaren Health Care

Mclaren Health Care is a non-profit healthcare system with an annual revenue of $6.6 billion. It operates an extensive network across Michigan, which includes 14 hospitals with a total bed capacity of 2,624. The organization is supported by a team of 490 physicians and has a workforce of 28,000 full-time staff. Additionally, Mclaren maintains contractual relationships with 113,000 providers, extending its reach into Indiana.

Notification and Impact

Mclaren has published a statement on its website regarding the intrusion and has also notified US authorities. The organization has taken steps to inform all individuals affected by the incident.

The security breach was identified by Mclaren on August 22, 2023. Further investigations, conducted with the assistance of external cybersecurity experts, revealed that the breach had compromised its systems since July 28, 2023.

Evidence shows that an unauthorized threat actor accessed data on August 31. By October 10, it was confirmed that the following data types had been exposed:

  • Full name
  • Social Security number (SSN)
  • Health insurance information
  • Date of birth
  • Billing or claims information
  • Diagnosis
  • Physician information
  • Medical record number
  • Medicare/Medicaid information
  • Prescription/medication information
  • Diagnostic results and treatment information

The specific types of data exposed vary for each individual, depending on the information they shared with Mclaren and the services they received.

Response and Recommendations

All impacted individuals will receive a notification via email, containing instructions on how to enroll in identity protection services for 12 months.

Mclaren has stated that there is currently no evidence of cybercriminals misusing the exposed data. However, they urge affected individuals to exercise caution with unsolicited communications and closely monitor their bank account activity.

“While there is currently no evidence that your information has been misused, we recommend that you remain vigilant, monitor and review all of your financial and account statements and explanations of benefits, and report any unusual activity to the institution of record and to law enforcement.” – Mclaren

ALPHV/BlackCat Ransomware Attack

Although Mclaren does not provide extensive details about the cyberattack, it is worth noting that the ALPHV/BlackCat ransomware group claimed responsibility for an attack on Mclaren’s network on October 4.

23andMe Enhances User Agreement to Shield Against Data Breach Lawsuits

Genetic testing service 23andMe has updated its user agreement to avoid potential data breach lawsuits. Customers must now agree to resolve any legal disputes through arbitration and won’t be able to file class-action lawsuits. The move follows several high-profile data breaches that have led to costly legal settlements for companies.

Genetic testing provider 23andMe is currently facing multiple lawsuits due to an October credential stuffing attack that resulted in the theft of customer data. In response, the company has made changes to its Terms of Use, making it more difficult for customers to sue them.

Last October, a cybercriminal attempted to sell 23andMe customer data but ultimately failed, leading them to leak the data of 1 million Ashkenazi Jews and 4.1 million people living in the United Kingdom.

Our IT Services team learned that the data was obtained through credential stuffing attacks used to breach customer accounts. The cybercriminals exploited a limited number of these accounts to access the ‘DNA Relatives’ feature and scrape the data of millions of individuals.

In a recent update, 23andMe disclosed that a total of 6.9 million people were affected by the breach — 5.5 million through the DNA Relatives feature and 1.4 million through the Family Tree feature.

Terms of Use Updates: Preventing Lawsuits?

As a result of the breach, 23andMe is now facing numerous lawsuits. In an effort to minimize legal troubles, the company updated its Terms of Use on November 30th. The updated terms now require mandatory arbitration for all disputes, prohibiting jury trials or class action lawsuits.

The updated Terms of Use state, “These terms of service contain a mandatory arbitration of disputes provision that requires the use of arbitration on an individual basis to resolve disputes in certain circumstances, rather than jury trials or class action lawsuits.”

23andMe sent emails to customers informing them of the change and advising that they had 30 days to notify the company at [email protected] if they disagreed with the new terms. Customers who disputed the update would remain on the previous Terms of Service.

However, Nancy Kim, a Chicago-Kent College of Law professor, told Axios that this change in the Terms of Use may not protect 23andMe from lawsuits. It could be difficult for the company to prove that they provided reasonable notice for customers to opt out of the new terms.

Imagine getting a DNA test for fun or curiosity, only to have your sensitive genetic information stolen by cybercriminals. That’s exactly what happened to millions of 23andMe customers this past October. As a result, the genetic testing provider is now facing multiple lawsuits and has decided to change its Terms of Use to make it harder for people to sue the company. Let’s dive into the details and see what this means for you.

The Credential Stuffing Attack on 23andMe

In October, a malicious threat actor tried to sell 23andMe customer data. When they failed to find a buyer, they leaked the data of 1 million Ashkenazi Jews and 4.1 million people living in the United Kingdom. We found out from 23andMe that the data was obtained through a credential stuffing attack, wherein the criminals breached customer accounts using stolen login information. They then used the “DNA Relatives” feature to scrape the data of millions of individuals.

Since then, 23andMe has reported that a total of 6.9 million people were impacted by the breach – 5.5 million through the “DNA Relatives” feature and 1.4 million through the “Family Tree” feature.

23andMe’s Response: Updating Terms of Use to Prevent Lawsuits

As you can imagine, this massive breach has led to a flurry of lawsuits against the company. In response, 23andMe updated its Terms of Use on November 30th to include a provision requiring mandatory arbitration for all disputes, rather than allowing for jury trials or class action lawsuits.

The updated Terms of Use state, “These terms of service contain a mandatory arbitration of disputes provision that requires the use of arbitration on an individual basis to resolve disputes in certain circumstances, rather than jury trials or class action lawsuits.”

Users were informed of this change via email, and they had 30 days from the notification to disagree with the new terms by contacting 23andMe. Those who disputed the update would remain on the previous Terms of Service.

Will This Change Protect 23andMe from Lawsuits?

According to Nancy Kim, a professor at the Chicago-Kent College of Law, it’s unlikely that this change in the Terms of Use will protect 23andMe from lawsuits. She told Axios that it would be difficult for the company to prove they gave customers reasonable notice to opt out of the new terms.

What Does This Mean for You?

This situation serves as a reminder of the importance of cybersecurity and protecting your personal data. If you’ve used 23andMe or other genetic testing services, it’s crucial to stay informed about any potential breaches and take action to protect yourself.

And for those of us who aren’t directly affected, this case demonstrates the need for strong cybersecurity measures across all industries, especially when sensitive data is involved. As we continue to rely more and more on technology, the potential for breaches and cyberattacks only increases.

Austal USA Suffers Cyberattack: What We Know

Austal USA, a shipbuilding company and contractor for the U.S. Department of Defense (DoD) and the Department of Homeland Security (DHS), recently confirmed a cyberattack against it. As a company that specializes in high-performance aluminum vessels, Austal USA plays a critical role in U.S. national security. Its American subsidiary is responsible for building the Independence class littoral combat ships for the U.S. Navy, which cost $360 million per unit, as well as an active $3.3 billion contract for constructing 11 patrol cutters for the U.S. Coast Guard.

Hunters International Ransomware Group Takes Credit

The Hunters International ransomware and data extortion group claimed responsibility for the breach, even leaking some information as proof of the intrusion. In response, a spokesperson for Austal USA confirmed the attack and stated that the company acted swiftly to mitigate the incident:

Austal USA recently discovered a data incident. We were able to quickly mitigate the incident resulting in no impact on operations.

Regulatory authorities, including the Federal Bureau of Investigation (FBI) and Naval Criminal Investigative Service (NCIS) were promptly informed and remain involved in investigating the cause of the situation and the extent of information that was accessed.

No personal or classified information was accessed or taken by the threat actor. We are working closely with the appropriate authorities and will continue to inform any stakeholders impacted by the incident as we learn new information.

Austal USA recognizes the seriousness of this event and the special responsibility we have as a DoD and DHS contractor. Our assessment is on-going as we seek to fully understand this incident so that we can prevent a similar occurrence.

The Threat of More Data Leaks

Hunters International has threatened to publish more stolen data from Austal’s systems in the coming days, including compliance documents, recruiting information, finance details, certifications, and engineering data. Austal USA has not disclosed whether the threat actor accessed engineering schematics or other proprietary U.S. Navy technology.

Who Are Hunters International?

Hunters International emerged recently as a ransomware-as-a-service (RaaS) operation and is suspected to be a rebrand of the Hive ransomware gang due to overlaps in their malware code. The group denies these allegations, claiming they are a new operation that purchased the encryptor source code from the now-defunct Hive. They say that encryption is not their end goal, but rather stealing data and using it as leverage to extort victims into paying ransoms. Currently, the gang’s data leak site lists over a dozen victims from various sectors and regions worldwide.
