Full Incident Analysis Transcript

In this Rankiteo incident briefing, we review the U.S. Department of Homeland Security breach identified under incident ID FBICISUS-UNI1767786135.

The analysis begins with a detailed overview of U.S. Department of Homeland Security's information like the linkedin page: https://www.linkedin.com/company/us-department-of-homeland-security, the number of followers: 988518, the industry type: Government Administration and the number of employees: 37484 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 571 and after the incident was 555 with a difference of -16 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 U.S. Department of Homeland Security and their customers.

Healthcare sector organizations recently reported "DHS Warning of Escalating Cyberattack Risks by Iran-Backed Hacking Groups", a noteworthy cybersecurity incident.

The U.S.

Impact assessments are still underway, so the full scope is not yet clear.

Formal response steps have not been shared publicly yet.

Overall, the incident is a reminder of why proactive monitoring and strong governance matter.

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 Brute Force (T1110) with high confidence (90%), supported by evidence indicating brute-force attacks, password spraying, and MFA fatigue (push bombing), Password Spraying (T1110.003) with high confidence (90%), supported by evidence indicating brute-force attacks, password spraying, and MFA fatigue (push bombing), and Multi-Factor Authentication Request Generation (T1621) with high confidence (90%), supported by evidence indicating mFA fatigue (push bombing). Under the Credential Access tactic, the analysis identified Brute Force (T1110) with high confidence (90%), supported by evidence indicating brute-force attacks, password spraying targeting poorly secured networks and Password Spraying (T1110.003) with high confidence (90%), supported by evidence indicating password spraying targeting poorly secured networks. Under the Persistence tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating iranian hackers acting as initial access brokers, breaching organizations. Under the Defense Evasion tactic, the analysis identified Modify Authentication Process (T1556) with moderate to high confidence (70%), supported by evidence indicating mFA fatigue (push bombing) to bypass authentication. Under the Lateral Movement tactic, the analysis identified Remote Services (T1021) with moderate to high confidence (70%), supported by evidence indicating iranian hackers breaching organizations in healthcare, government, IT sectors. Under the Impact tactic, the analysis identified Data Encrypted for Impact (T1486) with moderate to high confidence (80%), supported by evidence indicating br0k3r group selling access to ransomware affiliates. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with moderate to high confidence (70%), supported by evidence indicating iranian hackers acting as initial access brokers for ransomware affiliates. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
