Dartmouth College Breach Incident Score: Analysis & Impact (DAR5402054112725)

In this Rankiteo incident briefing, we review the Dartmouth College breach identified under incident ID DAR5402054112725.

The analysis begins with a detailed overview of Dartmouth College's information like the linkedin page: https://www.linkedin.com/company/dartmouthdickey, the number of followers: 130595, the industry type: Higher Education and the number of employees: 6301 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 648 and after the incident was 648 with a difference of 0 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 Dartmouth College and their customers.

Dartmouth College recently reported "Dartmouth College Data Breach via Oracle E-Business Suite Exploit", a noteworthy cybersecurity incident.

More than 35,000 people across multiple states had information stolen by hackers who attacked Dartmouth College during a campaign against Oracle E-Business Suite (EBS) software.

The disruption is felt across the environment, affecting Oracle E-Business Suite (EBS), and exposing Social Security numbers, financial account data and names, with nearly 35,000+ records at risk.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Installed Oracle-provided patch for the zero-day vulnerability, while recovery efforts such as Offered 1 year of credit monitoring to victims continue, and stakeholders are being briefed through Filed notices with regulators in Maine, California, Texas, and New Hampshire.

The case underscores how Completed (as of Dartmouth's disclosure), with advisories going out to stakeholders covering Victims offered 1 year of credit monitoring.

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 high confidence (100%), with evidence including zero-day vulnerability in Oracle E-Business Suite (EBS) exploited by Clop gang, and software vulnerability (Oracle EBS) listed as attack vector. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (70%), supported by evidence indicating social Security numbers, financial account details exfiltrated (implies post-exploitation credential/data access). Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (95%), with evidence including personally identifiable information (PII), financial data compromised (35,000+ records), and data exfiltration such as true in ransomware section. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with high confidence (90%), with evidence including clop gang leaking stolen data (implies exfiltration prior to public dump), and data exfiltration such as true confirmed in incident_details. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating ransomware such as data exfiltration such as true (though no encryption confirmed, Clop often combines exfil + encryption) and Data Destruction (T1485) with lower confidence (20%), supported by evidence indicating data exfiltration such as true (no explicit destruction, but Clop has destroyed data in past campaigns). Under the Defense Evasion tactic, the analysis identified Valid Accounts: Cloud Accounts (T1078.004) with moderate confidence (60%), supported by evidence indicating oracle E-Business Suite (EBS) (cloud/enterprise app) exploited; may involve abused legitimate sessions and Obfuscated Files or Information (T1027) with moderate to high confidence (70%), supported by evidence indicating data sold on dark web (implies obfuscation for covert exfiltration). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
