Security firms warn of new cyber threat

UAE – Two cyber security companies said they have uncovered a sophisticated piece of malicious software capable of causing power outages by ordering industrial computers to shut down electricity transmission, according to a Reuters report.

Analysis of the malware, known as Crash Override or Industroyer, indicates it was likely used in a December 2016 cyber attack that cut power in Ukraine, according to the firms, Slovakian security software maker ESET and U.S. critical-infrastructure security firm Dragos Inc.

The discovery may stoke fears about cyber vulnerabilities in power grids that have intensified in the wake of the December Ukraine attack, and one a year earlier that also cut power in that nation.

Ukraine authorities have previously blamed Russia for the attacks on its grid. Moscow has denied responsibility.
