Cybersecurity and Infrastructure Security Agency Breach Incident Score: Analysis & Impact (CIS1765238766)

In this Rankiteo incident briefing, we review the Cybersecurity and Infrastructure Security Agency breach identified under incident ID CIS1765238766.

The analysis begins with a detailed overview of Cybersecurity and Infrastructure Security Agency's information like the linkedin page: https://www.linkedin.com/company/cisagov, the number of followers: 586152, the industry type: Government Administration and the number of employees: 1741 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 544 and after the incident was 524 with a difference of -20 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 Cybersecurity and Infrastructure Security Agency and their customers.

A newly reported cybersecurity incident, "BRICKSTORM Malware Campaign by Chinese Hackers", has drawn attention.

An ongoing campaign by Chinese hackers using the sophisticated BRICKSTORM malware to target public sector organizations and IT companies for long-term espionage purposes.

The disruption is felt across the environment, affecting Windows and VMware vSphere, and exposing Credentials, sensitive data.

Formal response steps have not been shared publicly yet.

The case underscores how Ongoing.

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 Exploit Public-Facing Application (T1190) with moderate confidence (50%), supported by evidence indicating targets public sector organizations and IT companies and Supply Chain Compromise (T1195) with lower confidence (40%), supported by evidence indicating sophisticated BRICKSTORM malware with advanced obfuscation. Under the Persistence tactic, the analysis identified Pre-OS Boot (T1542) with moderate confidence (60%), supported by evidence indicating malware reinstalls itself if removed or disrupted, Create or Modify System Process: Windows Service (T1543.003) with moderate to high confidence (70%), supported by evidence indicating long-term backdoor for stealthy data exfiltration, and Boot or Logon Autostart Execution: Registry Run Keys / Startup Folder (T1547.001) with moderate confidence (60%), supported by evidence indicating malware targets Windows environments. Under the Privilege Escalation tactic, the analysis identified Valid Accounts (T1078) with moderate to high confidence (80%), supported by evidence indicating capture legitimate credentials through various means and Exploitation for Privilege Escalation (T1068) with moderate confidence (60%), supported by evidence indicating targets VMware vSphere environments. Under the Defense Evasion tactic, the analysis identified Obfuscated Files or Information (T1027) with high confidence (90%), supported by evidence indicating numerous advanced obfuscation features, Hide Artifacts: Run Virtual Instance (T1564.006) with moderate to high confidence (80%), supported by evidence indicating create hidden virtual machines to conceal their activities, and Indicator Removal: Clear Windows Event Logs (T1070.001) with moderate to high confidence (70%), supported by evidence indicating average dwell time of 393 days. Under the Credential Access tactic, the analysis identified OS Credential Dumping (T1003) with moderate to high confidence (80%), supported by evidence indicating capture legitimate credentials through various means and Credentials from Password Stores (T1555) with moderate to high confidence (70%), supported by evidence indicating targets Windows environments for credential access. Under the Discovery tactic, the analysis identified Account Discovery (T1087) with moderate to high confidence (70%), supported by evidence indicating long-term espionage with credential capture and File and Directory Discovery (T1083) with moderate confidence (60%), supported by evidence indicating stealthy data exfiltration from target networks. Under the Lateral Movement tactic, the analysis identified Remote Services: Remote Desktop Protocol (T1021.001) with moderate confidence (60%), supported by evidence indicating targets VMware vSphere environments and Remote Services: SMB/Windows Admin Shares (T1021.002) with moderate to high confidence (70%), supported by evidence indicating long-term backdoor access in Windows environments. Under the Collection tactic, the analysis identified Data from Local System (T1005) with moderate to high confidence (80%), supported by evidence indicating stealthy data exfiltration for espionage purposes and Data from Network Shared Drive (T1039) with moderate to high confidence (70%), supported by evidence indicating targets public sector and IT companies. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate to high confidence (70%), supported by evidence indicating long-term backdoor with stealthy communication and Encrypted Channel: Asymmetric Cryptography (T1573.002) with moderate confidence (60%), supported by evidence indicating advanced obfuscation features in malware. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating stealthy data exfiltration via long-term backdoor and Exfiltration Over Alternative Protocol: Exfiltration Over Unencrypted/Obfuscated Non-C2 Protocol (T1048.003) with moderate to high confidence (70%), supported by evidence indicating advanced obfuscation features for data exfiltration. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
