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 745 and after the incident was 690 with a difference of -55 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 ENCON Commercial Services and their customers.

EnCon recently reported "EnCon Data Breach Incident (2025)", a noteworthy cybersecurity incident.

EnCon reported to the Attorney General of the Commonwealth of Massachusetts that sensitive personally identifiable information (PII) in its care may have been compromised.

The disruption is felt across the environment, and exposing Name and Social Security number.

In response, teams activated the incident response plan, and began remediation that includes 24 months of complimentary credit monitoring services for affected individuals, and stakeholders are being briefed through Mailing breach notification letters to impacted individuals; filing notice with the Attorney General of Massachusetts.

The case underscores how Ongoing (as of November 19, 2025, notifications were being mailed), with advisories going out to stakeholders covering Breach notification letters mailed to impacted individuals, including details of exposed data types and credit monitoring offer.

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 Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (85%), with evidence including exposed data includes names and Social Security numbers (SSNs), and personally Identifiable Information (PII) in its care may have been compromised. Under the Exfiltration tactic, the analysis identified Exfiltration Over Alternative Protocol (T1048) with moderate to high confidence (75%), with evidence including sensitive PII ... may have been compromised (implied unauthorized transfer), and data breach with high identity theft risk due to exposure of SSNs and Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (70%), supported by evidence indicating lack of transparency regarding the attack vector (suggests possible unencrypted exfiltration). Under the Impact tactic, the analysis identified Data Manipulation: Staged Data for Exfiltration (T1595.001) with moderate to high confidence (70%), supported by evidence indicating sensitive PII ... may have been compromised (implies staging before exfiltration) and Data Destruction (T1485) with lower confidence (10%), supported by evidence indicating no confirmation of encryption or deletion, but breach implies unauthorized access. Under the Initial Access tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (65%), with evidence including lack of transparency regarding the attack vector (common with credential abuse), and no phishing/ransomware mentioned; possible insider or compromised account and Exploit Public-Facing Application (T1190) with moderate confidence (60%), supported by evidence indicating no attack vector disclosed (public-facing app exploitation is a common unknown vector). Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with moderate confidence (60%), supported by evidence indicating significant failure in safeguarding critical personal data (implies poor credential hygiene). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
