The case underscores how with advisories going out to stakeholders covering Guidance on protecting personal information (e.g., monitoring credit reports, placing fraud alerts, watching for suspicious activity related to medical or insurance records).

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 (T1078) with moderate to high confidence (70%), supported by evidence indicating significant security failure within HOTBHN’s systems and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating exact cause and responsible party remain undisclosed. Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate to high confidence (70%), supported by evidence indicating exposure of personally identifiable information (PII) and PHI. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with moderate to high confidence (80%), supported by evidence indicating data breach impacting 1,309 individuals, exposed sensitive personal and medical data and Automated Exfiltration (T1020) with moderate confidence (60%), supported by evidence indicating scope of compromised data suggests a significant security failure. Under the Impact tactic, the analysis identified Data Destruction (T1485) with moderate confidence (50%), supported by evidence indicating high sensitivity of data such as High and Data Encrypted for Impact (T1486) with lower confidence (40%), supported by evidence indicating data encryption such as null (implied absence of ransomware). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
