In this Rankiteo incident briefing, we review the Cybersecurity and Infrastructure Security Agency breach identified under incident ID CIS1765368172.

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 491 and after the incident was 472 with a difference of -19 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.

Multiple U.S. states' drinking water systems recently reported "Indictment of Victoria Eduardovna Dubranova for Cyberattacks on Critical Infrastructure", a noteworthy cybersecurity incident.

The US Justice Department has indicted Ukrainian national Victoria Eduardovna Dubranova for her alleged role in cyberattacks aimed at disrupting critical infrastructure worldwide.

The disruption is felt across the environment, affecting Water systems, Food supply chains and Public services.

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 to high confidence (70%), supported by evidence indicating dDoSia tool deployed to take down government websites and Trusted Relationship (T1199) with moderate to high confidence (80%), supported by evidence indicating groups received direction and funding from Russian intelligence (GRU). Under the Impact tactic, the analysis identified Network Denial of Service (T1498) with high confidence (95%), supported by evidence indicating custom DDoSia tool used by NoName057(16) to take down government websites, Endpoint Denial of Service: Application or System Exploitation (T1499.004) with high confidence (90%), supported by evidence indicating breaches of U.S. drinking water systems causing spills and failures, and Data Manipulation: Stored Data Manipulation (T1565.001) with moderate to high confidence (80%), supported by evidence indicating attack on meat processing facility caused ammonia leak and food spoilage. Under the Resource Development tactic, the analysis identified Acquire Infrastructure: Virtual Private Server (T1583.003) with moderate to high confidence (80%), supported by evidence indicating 100 servers linked to NoName057(16) dismantled in July 2025, Obtain Capabilities: Tool (T1588.002) with high confidence (90%), supported by evidence indicating custom DDoSia tool developed and deployed by NoName057(16), and Compromise Accounts (T1586) with moderate to high confidence (70%), supported by evidence indicating recruited global volunteers with cryptocurrency rewards for DDoS attacks. Under the Command and Control tactic, the analysis identified Proxy (T1090) with moderate to high confidence (70%), supported by evidence indicating infrastructure built by CISM, a Russian state-sponsored IT group. Under the Defense Evasion tactic, the analysis identified Valid Accounts (T1078) with moderate confidence (60%), supported by evidence indicating groups operated with alleged state backing and direction from GRU. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
