Elektrocentromontazh

Elektrocentromontazh (ECM), also known by variations including JSC Elektrocentromontazh and Электроцентромонтаж, is a Russian organization headquartered in Russia. Its core function involves critical power infrastructure, specifically the installation and maintenance of electrical equipment. ECM operates across numerous energy facilities within Russia, indicating a significant role in the national energy sector. The organization's responsibilities extend to servicing electrical systems tied to nuclear power plants and rail networks, highlighting its involvement in essential national infrastructure. ECM also interacts with government energy departments, suggesting its operations support state-managed energy assets. This positions ECM as a key entity within Russia's strategic energy landscape, responsible for ensuring the functionality of vital electrical components.

In late April 2022, ECM became a prominent target in a major cybersecurity incident. The hacktivist collective Anonymous executed a cyberattack against ECM as part of their coordinated #OpRussia campaign. This attack resulted in the significant compromise of ECM's internal communications. Anonymous successfully exfiltrated a vast quantity of data totaling 1.7 terabytes, which included approximately 1.23 million internal emails. The stolen data was subsequently leaked via the platform DDoSecrets. This breach exposed sensitive operational communications directly related to ECM's work on nuclear plants, rail networks, and government energy projects. This incident underscored ECM's critical role and the potential consequences of cyber intrusions targeting national infrastructure entities.
