What is BlackEnergy malware?
BlackEnergy is a trojan malware designed for distributed denial-of-service (DDoS) attacks but later adapted for espionage and destructive operations. Created primarily to infiltrate and disrupt systems, it has aliases such as “BE2.” Its modular design allows attackers to deploy various payloads, making it especially dangerous for industries managing critical infrastructure.
When was BlackEnergy first discovered?
BlackEnergy was first identified in 2007 as a DDoS tool and gained attention due to its evolution into a cyberweapon. The group Sandworm is linked to its use, primarily against geopolitical and industrial targets.
Who created BlackEnergy?
The identities behind BlackEnergy point to the Sandworm group, a cybercriminal organization suspected to have ties to Russian state-sponsored activities. Their operations demonstrate a high level of sophistication and coordination.
What does BlackEnergy target?
BlackEnergy focuses on critical infrastructure, industrial control systems (ICS), and governmental systems. It has been deployed in cyberattacks on energy grids, media outlets, and financial systems, with a particular emphasis on geopolitical regions like Ukraine.
BlackEnergy distribution method
The malware spreads through phishing emails containing malicious attachments and infected websites exploiting software vulnerabilities. Spear-phishing has been a common tactic, ensuring that victims unwittingly download the trojan by opening seemingly legitimate documents.
Technical analysis of BlackEnergy malware
BlackEnergy operates as a modular trojan, using plugins to adapt its capabilities. These plugins enable espionage, sabotage, and system disruption. For example, it can delete or overwrite system files, disable antivirus software, establish persistence, and evade detection. Its variants are highly stealthy, utilizing rootkits and encrypted communications to avoid detection.

How to know if you’re infected with BlackEnergy?
Signs of an infection include unusual system activity, such as excessive network traffic, disabled antivirus solutions, and unexpected system reboots. For ICS operators, operational anomalies or unexplained outages might indicate BlackEnergy.
BlackEnergy removal instructions
Manual removal of BlackEnergy is complex and risky due to its stealth and system-level impacts. Use advanced EDR solutions or Huntress’s remediation tools to identify and remove the trojan. It is also prudent to isolate infected systems and review logs for root cause analysis.
Is BlackEnergy still active?
While the original versions of BlackEnergy are no longer widespread, its variants and techniques influenced more recent threats. Vigilance against similar modular malware remains critical in defending critical systems.
Mitigation & prevention strategies
To mitigate the risk of BlackEnergy, organizations should implement robust cybersecurity measures, including multi-factor authentication (MFA), regular patch management, user awareness training, and network monitoring. Employing a managed detection service, like Huntress’s 24/7 monitoring, can help detect and contain threats early.
