Consensus Health Breach Incident Score: Analysis & Impact (CONCON1766685282)

In this Rankiteo incident briefing, we review the Consensus Health breach identified under incident ID CONCON1766685282.

The analysis begins with a detailed overview of Consensus Health's information like the linkedin page: https://www.linkedin.com/company/consensus-health, the number of followers: 6248, the industry type: Hospitals and Health Care and the number of employees: 187 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 762 and after the incident was 603 with a difference of -159 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 Consensus Health and their customers.

On 18 October 2023, Continuum Health Alliance LLC disclosed Data Breach issues under the banner "Continuum Health Data Breach Class Action Settlement".

Continuum Health Alliance LLC and Consensus Medical Group LLC agreed to settle a lawsuit alleging they failed to adequately protect private information during a cybersecurity incident that occurred Oct.

The disruption is felt across the environment, and exposing Personal and protected health information, with nearly 380,000 records at risk, plus an estimated financial loss of $3,100,000 (settlement fund).

In response, and stakeholders are being briefed through Notices sent to affected individuals.

The case underscores how Settled, with advisories going out to stakeholders covering Notices sent to affected individuals with claim instructions.

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 failure to adequately protect private information (implied weak access controls) and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating cybersecurity incident on Oct 18-19, 2023 (no specific vector disclosed). Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate to high confidence (70%), supported by evidence indicating failure to adequately protect private information (implied weak credential management). Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with moderate to high confidence (80%), supported by evidence indicating data breach compromised personal and protected health information of 380,000 individuals and Automated Exfiltration (T1020) with moderate to high confidence (70%), supported by evidence indicating large-scale data exposure (380,000 records) suggests automated methods. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate confidence (50%), supported by evidence indicating no ransomware details, but high-impact breach suggests possible encryption and Data Manipulation (T1565) with lower confidence (40%), supported by evidence indicating settlement includes identity theft insurance (implies potential misuse). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
