The case underscores how Settled (class action lawsuit resolved with $1.4M fund), with advisories going out to stakeholders covering Notification letters sent to affected U.S. residents; claim submission instructions provided (online/mail).

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 Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating cyberattack detected on October 12, 2023 (no vector specified, but PII/PHI/PCI exfiltration suggests application compromise) and Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating threat actors accessed... sensitive personal and health information (possible abuse of legitimate credentials). Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (95%), supported by evidence indicating exposed information included names, SSNs, driver’s license numbers, passport numbers, credit/debit cards, medical records. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (85%), supported by evidence indicating data exfiltration such as Yes (no protocol specified, but high-volume PII/PHI/PCI suggests bulk transfer). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating ransomware such as null (no ransomware mentioned, but data breach with settlement suggests potential leverage) and Data Destruction (T1485) with lower confidence (20%), supported by evidence indicating no explicit destruction mentioned, but high-risk data exposure implies potential follow-on misuse. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with moderate to high confidence (70%), supported by evidence indicating alleged failure to adequately protect personal and health information (implies poor credential hygiene). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
