Mindpath Health Breach Incident Score: Analysis & Impact (MIN1764604608)

In this Rankiteo incident briefing, we review the Mindpath Health breach identified under incident ID MIN1764604608.

The analysis begins with a detailed overview of Mindpath Health's information like the linkedin page: https://www.linkedin.com/company/mindpath-health, the number of followers: 4869, the industry type: Mental Health Care and the number of employees: 585 employees

After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 694 and after the incident was 531 with a difference of -163 which is could be a good indicator of the severity and impact of the incident.

In the next step of the video, we will analyze in more details the incident and the impact it had on Mindpath Health and their customers.

On 10 January 2023, Mindpath Health (operated by Community Psychiatry Management, LLC) disclosed Data Breach and Unauthorized Access issues under the banner "Mindpath Health Email Data Breaches (2022)".

Unauthorized individuals gained access to Microsoft Office 365 business accounts of Mindpath Health in March and June 2022, exposing protected health information (PHI) of 193,947 individuals.

The disruption is felt across the environment, affecting Microsoft Office 365 Email Accounts (2 accounts), and exposing True, with nearly 193947 records at risk, plus an estimated financial loss of $3.5 million (settlement amount).

In response, teams activated the incident response plan, while recovery efforts such as Notification Letters to Affected Individuals (2023-01-10) continue, and stakeholders are being briefed through Delayed Disclosure (7 months post-breach).

The case underscores how Completed (breach confirmed in 2022, litigation ongoing as of 2024), with advisories going out to stakeholders covering Notification Letters (2023-01-10).

Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.

The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.

Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with high confidence (95%), with evidence including unauthorized individuals gained access to Microsoft Office 365 business accounts, and two email accounts had been subject to unauthorized access and Phishing: Spearphishing Link (T1566.002) with moderate to high confidence (70%), supported by evidence indicating attack vector such as Phishing (likely, though not explicitly stated). Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with moderate to high confidence (80%), supported by evidence indicating vulnerability exploited such as Weak Email Security Controls, Lack of Multi-Factor Authentication (MFA) (inferred) and Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating weak Email Security Controls implies potential brute-force or credential-stuffing. Under the Collection tactic, the analysis identified Email Collection (T1114) with high confidence (95%), with evidence including microsoft Office 365 business accounts that contained the protected health information, and file types exposed such as Emails, Attachments (likely). Under the Exfiltration tactic, the analysis identified Exfiltration Over Web Service: Exfiltration to Cloud Storage (T1048.002) with high confidence (90%), with evidence including data exfiltration such as true, and unauthorized access to Microsoft Office 365 business accounts and Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating data exfiltration such as true (method unspecified, but likely via C2 or email forwarding). Under the Defense Evasion tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with high confidence (90%), supported by evidence indicating suspicious account activity detected only during routine audit, implying use of legitimate credentials and Impair Defenses: Disable or Modify Cloud Logs (T1562.008) with moderate confidence (60%), supported by evidence indicating delayed Detection (breach occurred in March/June 2022, detected in June 2022) suggests possible log tampering. Under the Impact tactic, the analysis identified Data Destruction (T1485) with lower confidence (10%), supported by evidence indicating no explicit evidence, but included due to high sensitivity of exposed PHI/PII, Data Encrypted for Impact (T1486) with lower confidence (5%), supported by evidence indicating no ransomware mentioned, but included for completeness given data breach context, and Cloud Service Dashboards (T1538) with lower confidence (30%), supported by evidence indicating microsoft Office 365 business accounts access could imply dashboard misuse for data exposure. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
