Threat Analysis of BlackEnergy Malware for Synchrophasor based Real time Control and Monitoring in Smart Grid
The BlackEnergy malware targeting critical infrastructures has a long history. It evolved over time from a simple DDoS platform to a quite sophisticated plug in based malware. The plug in architecture has a persistent malware core with easily installable attack specific modules for DDoS, spamming, info stealing, remote access, boot sector formatting etc. BlackEnergy has been involved in several high profile cyber physical attacks including the recent Ukraine power grid attack in December 2015. This paper investigates the evolution of BlackEnergy and its cyber attack capabilities. It presents a basic cyber attack model used by BlackEnergy for targeting industrial control systems. In particular, the paper analyzes cyber threats of BlackEnergy for synchrophasor based systems which are used for real time control and monitoring functionalities in smart grid. Several BlackEnergy based attack scenarios have been investigated by exploiting the vulnerabilities in two widely used synchrophasor communication standards: (i) IEEE C37.118 and (ii) IEC 61850 90 5. Further, the paper also investigates protection strategies for detection and prevention of BlackEnergy based cyber physical attacks.
