EDP Breach Incident Score: Analysis & Impact (EDP1769207360)

In this Rankiteo incident briefing, we review the EDP breach identified under incident ID EDP1769207360.

The analysis begins with a detailed overview of EDP's information like the linkedin page: https://www.linkedin.com/company/edp, the number of followers: 459233, the industry type: Utilities and the number of employees: 13888 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 797 and after the incident was 783 with a difference of -14 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 EDP and their customers.

On 29 December 2023, Polish power plants and wind turbine networks disclosed Cyberattack issues under the banner "Russia’s Sandworm Unit Targets Poland’s Power Grid in Failed Cyberattack".

Russia’s elite Sandworm hacking unit linked to the GRU attempted to disrupt Poland’s energy infrastructure in late December.

The disruption is felt across the environment, affecting Power plants, wind turbine networks, communication links.

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.

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 Supply Chain Compromise (T1195) with lower confidence (40%), supported by evidence indicating targeted critical facilities and communication links and External Remote Services (T1133) with moderate confidence (50%), supported by evidence indicating assault targeted communication links between renewable energy installations. Under the Execution tactic, the analysis identified User Execution: Malicious File (T1204.002) with moderate to high confidence (70%), supported by evidence indicating destructive DynoWiper malware deployed against two Polish power plants and Command and Scripting Interpreter (T1059) with moderate confidence (60%), supported by evidence indicating dynoWiper designed to erase data and render systems inoperable. Under the Impact tactic, the analysis identified Data Destruction (T1485) with high confidence (90%), supported by evidence indicating dynoWiper is designed for pure destruction, erasing data and rendering systems inoperable and Data Manipulation: Stored Data Manipulation (T1565.001) with moderate to high confidence (70%), supported by evidence indicating attack aimed to cripple operations of power plants and wind turbine networks. Under the Defense Evasion tactic, the analysis identified Indicator Removal: File Deletion (T1070.004) with moderate to high confidence (80%), supported by evidence indicating dynoWiper erasing data and rendering systems inoperable. These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
