Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Cybersecurity and Infrastructure Security Agency breach identified under incident ID CIS1779207877.
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: 598835, the industry type: Government Administration and the number of employees: 1729 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 432 and after the incident was 350 with a difference of -82 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.
Cybersecurity and Infrastructure Security Agency (CISA) recently reported "CISA Dodges Potential Breach After Researcher Discovers Exposed Credentials", a noteworthy cybersecurity incident.
A security researcher uncovered publicly exposed credentials that could have granted access to CISA’s cloud and internal systems.
The disruption is felt across the environment, affecting CISA’s cloud and internal systems, Department of Homeland Security systems.
Formal response steps have not been shared publicly yet.
The case underscores how teams are taking away lessons such as Importance of proper credential management and securing third-party repositories, and recommending next steps like Revoking exposed credentials, enforcing stricter access controls, and improving contractor oversight.
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 Unsecured Credentials: Credentials In Files (T1552.001) with high confidence (90%), supported by evidence indicating plaintext credentials including access tokens and cloud keys stored in unprotected spreadsheets and Supply Chain Compromise: Compromise Software Dependencies and Development Tools (T1195.001) with moderate to high confidence (70%), supported by evidence indicating credentials exposed in a GitHub repository maintained by a CISA contractor. Under the Credential Access tactic, the analysis identified Unsecured Credentials (T1552) with high confidence (95%), supported by evidence indicating access tokens and cloud keys found in unprotected spreadsheets within a GitHub repository and Unsecured Credentials: Credentials In Files (T1552.001) with high confidence (90%), supported by evidence indicating credentials stored in plaintext in spreadsheets. Under the Defense Evasion tactic, the analysis identified Hide Artifacts: Hidden Files and Directories (T1564.001) with moderate confidence (60%), supported by evidence indicating credentials stored in unprotected spreadsheets within a GitHub repository. Under the Exfiltration tactic, the analysis identified Transfer Data to Cloud Account (T1537) with moderate confidence (50%), supported by evidence indicating exposed credentials could have granted access to CISA’s cloud systems. Under the Impact tactic, the analysis identified Resource Hijacking (T1496) with moderate confidence (60%), supported by evidence indicating exposed cloud keys could have provided entry to CISA and DHS systems and Endpoint Denial of Service: Application or System Exploitation (T1499.004) with lower confidence (40%), supported by evidence indicating potential access to critical cybersecurity agency systems. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
