Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the The Harvard & MIT Cooperative Society breach identified under incident ID HAR1765116119.

The analysis begins with a detailed overview of The Harvard & MIT Cooperative Society's information like the linkedin page: https://www.linkedin.com/company/harvardmitcoop, the number of followers: 1021, the industry type: Retail and the number of employees: 50 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 768 and after the incident was 657 with a difference of -111 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 The Harvard & MIT Cooperative Society and their customers.

On 14 May 2025, Co-op disclosed Ransomware Attack (Attempted) issues under the banner "Co-op Cyber Attack Averted by Self-Imposed Shutdown".

Co-op narrowly averted being locked out of its computer systems during a cyber attack that saw customer data stolen and store shelves left bare.

The disruption is felt across the environment, affecting Computer systems (partially), and exposing Customer data stolen.

In response, teams activated the incident response plan, moved swiftly to contain the threat with measures like Took computer services offline.

The case underscores how Ongoing, teams are taking away lessons such as Self-imposed immediate-term disruption can prevent longer-term criminal-imposed disruption.

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.

MITRE ATT&CK® Correlation Analysis

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 hackers claimed responsibility for both attacks (Co-op and M&S) and Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating attack vector and vulnerability exploited not specified. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating hackers attempted to deploy ransomware (implies credential compromise). Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (80%), with evidence including attempted to infect Co-op with ransomware, and data encryption such as Attempted but failed. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), with evidence including customer data stolen, and data exfiltration such as Yes. Under the Defense Evasion tactic, the analysis identified Impair Defenses: Disable or Modify Tools (T1562.001) with moderate to high confidence (70%), supported by evidence indicating co-op took computer services offline to prevent ransomware deployment. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
