Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Summit breach identified under incident ID SUMTEX1769189079.
The analysis begins with a detailed overview of Summit's information like the linkedin page: https://www.linkedin.com/company/summitco, the number of followers: 16589, the industry type: Events Services and the number of employees: 370 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 760 and after the incident was 695 with a difference of -65 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 Summit and their customers.
Heart South Cardiovascular Group recently reported "Dark Web Data Breaches Surge, Exposing Millions to Identity Theft and Fraud", a noteworthy cybersecurity incident.
A sharp rise in data breaches has left the personal and health information of millions vulnerable, with much of the compromised data appearing on the Dark Web.
The disruption is felt across the environment, and exposing Personally Identifiable Information (PII), Protected Health Information (PHI) and Social Security numbers, plus an estimated financial loss of Billions in losses tied to identity theft (FTC).
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as Organizations take an average of 194 days to detect a breach and another 64 days to contain it, allowing stolen data to circulate undetected. Long-term vigilance is necessary as exposed data may remain in circulation indefinitely.
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 Phishing (T1566) with high confidence (90%), supported by evidence indicating attack vector such as Phishing and Exploit Public-Facing Application (T1190) with moderate to high confidence (70%), supported by evidence indicating vulnerability exploited such as Outdated software. Under the Execution tactic, the analysis identified User Execution (T1204) with moderate to high confidence (80%), supported by evidence indicating vulnerability exploited such as Inadequate employee training. Under the Credential Access tactic, the analysis identified Credentials from Password Stores (T1555) with moderate to high confidence (80%), supported by evidence indicating data compromised such as Bank login credentials and Brute Force (T1110) with moderate confidence (60%), supported by evidence indicating weak security controls exploited. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating data compromised such as PII, PHI, Medical records. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating data exfiltration such as Traded in underground marketplaces and Exfiltration Over Web Service (T1567) with moderate to high confidence (70%), supported by evidence indicating dark Web exposure of compromised data. Under the Impact tactic, the analysis identified Data Destruction (T1485) with moderate confidence (50%), supported by evidence indicating data breach with high identity theft risk and Data Manipulation: Transmitted Data Manipulation (T1565.002) with moderate confidence (60%), supported by evidence indicating billions in losses tied to identity theft (FTC). Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (70%), supported by evidence indicating bank login credentials compromised and Hide Artifacts (T1564) with moderate to high confidence (80%), supported by evidence indicating 194 days to detect breach, 64 days to contain. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
