I found this article quite interesting since I recently entered the environmental sector for work.
A hacker group known as “Dragonfly” is behind recent cyber attacks on the energy industry in Europe and North America. There was strong activity shown in the United States, Turkey and Switzerland. These attacks can disrupt energy operations in both continents. The impact of the attacks has been minimal, but many are concerned about the future. The motive behind these attacks has not been determined. There have been no signs of motivation in regards to monetary, extortion or economic espionage. Due to the targets of the attacks, the level and types of attacks and collection of data and information, it has been concluded that a nation-state may be behind this. Additionally, the attackers are using unsophisticated methods to hack into the SCADA systems. They are not exploiting zero-day vulnerabilities, but are taking the social engineering route. The Dragonfly hackers are collecting credentials and performing reconnaissance on the systems they are targeting.
