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 753 and after the incident was 667 with a difference of -86 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 SAX and their customers.

An unauthorized person gained access to Sax LLP’s network in August 2024 and may have acquired records containing personally identifiable information (PII) of over two hundred thousand individuals.

The disruption is felt across the environment, affecting Sax LLP’s network, and exposing Personally identifiable information (PII), with nearly 200000 records at risk.

In response, and stakeholders are being briefed through Public disclosure via press release.

The case underscores how Ongoing (Class action investigation), with advisories going out to stakeholders covering Individuals impacted may be entitled to compensation; advised to contact Lynch Carpenter LLP.

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 unauthorized actor accessed Sax’s network, Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating attack vector or vulnerability exploited not disclosed, and External Remote Services (T1133) with moderate confidence (60%), supported by evidence indicating access to Sax LLP’s network without further details. Under the Credential Access tactic, the analysis identified Brute Force (T1110) with moderate confidence (50%), supported by evidence indicating no details on attack vector; brute force plausible and Unsecured Credentials (T1552) with moderate confidence (60%), supported by evidence indicating unauthorized access implies possible credential compromise. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (80%), supported by evidence indicating potentially exfiltrated sensitive records and Automated Exfiltration (T1020) with moderate to high confidence (70%), supported by evidence indicating large volume of PII (200,000 records) suggests automation. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with lower confidence (30%), supported by evidence indicating no ransomware details; encryption not confirmed and Data Manipulation: Stored Data Manipulation (T1565.001) with lower confidence (40%), supported by evidence indicating no evidence of data manipulation; included due to PII exposure. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
