Michigan MedicineBreach80403/2022MIC173012522Link
Rankiteo Explanation :
Attack with significant impact with customers data leaks

Description: The patient information of Michigan Medicine was leaked in a data security incident after an employee email account was compromised. A newly-hired employee accessed patients' electronic medical records of about 2,920 patients without any business need. The compromised information included demographic and clinical information such as diagnosis, treatment, and test results. The employee's excess was immediately cut off and further investigation revealed that no information was misused and the employee checked the records out of curiosity.

Michigan MedicineCyber Attack100508/2022MIC05131122Link
Rankiteo Explanation :
Attack threatening the organization's existence

Description: Michigan Medicine was targeted in a cyber attack that lured employees to a webpage that got them to enter their login information. Four Michigan Medicine employees entered login information and accepted multifactor authentication prompts which gave attackers to access their email accounts and resulted in a breach. The incident compromised the patients' names, addresses, birth dates, treatment information, medical record numbers, and health insurance information of about 33,850 patients. Michigan Medicine took steps immediately to investigate the matter and implemented additional safeguards to reduce risk to our patients.

Michigan MedicineCyber Attack25101/2023MIC8259223Link
Rankiteo Explanation :
Attack without any consequences

Description: Michigan Medicine was targeted in a cyber attack after that experienced intermittent problems with its public websites as a result on a third-party vendor they used to host some of their sites. They worked with the third-party to mitigate it and expect to have sites fully functional as soon as possible. Public websites hosted by a third-party provider are the only websites that have been targeted. All patient information is secure and not included on any of the compromised sites. Michigan Medicine took steps immediately to investigate the matter and implemented additional safeguards to reduce risk to our patients.

Michigan MedicineData Leak60308/2019MIC4393423Link
Rankiteo Explanation :
Attack with significant impact with internal employee data leaks

Description: Michigan Medicine notified approximately 5,500 patients about a phishing email campaign that have exposed some of their health information. During the campaign, emails containing a malicious link were sent to over 3,200 Michigan Medicine employees. This email was opened by three employees, giving the attacker access to their email accounts. The compromised information includes names, medical record numbers, addresses, dates of birth, diagnostic and treatment information, and health insurance information. As soon as Michigan Medicine learned that the email accounts were compromised, they were disabled so no further access could take place until the passwords were changed.
