Cybersecurity Tools to Protect Solar, Wind Power on the Grid
Solar panels and wind turbines are projected to produce 44% of America’s electricity by 2050, but they present cybersecurity challenges. They have sensors, controllers, actuators or inverters which are directly or indirectly connected to the internet using insecure connectivity to legacy electric grid systems. They have complex physics. They’re subject to advanced persistent threats. And there will be more and more of them going online.

Ransomware Attacks: Death Threats, Endangered Patients and Millions of Dollars in Damages
By Dino Jahic
A ransomware attack on Change Healthcare, a company that processes 15 billion health care transactions annually and deals with 1 in 3 patient records in the United States, is continuing to cause massive disruptions nearly three weeks later. The incident, which started on February 21, has been called the “most significant cyberattack on the U.S. health care system” by the American Hospital Association. It is just the latest example of an increasing trend.
Chinese Government Hackers Targeted Critics of China, U.S. Businesses and Politicians
An indictment was unsealed Monday charging seven nationals of the People’s Republic of China (PRC) with conspiracy to commit computer intrusions and conspiracy to commit wire fraud for their involvement in a PRC-based hacking group that spent approximately 14 years targeting U.S. and foreign critics, businesses, and political officials in furtherance of the PRC’s economic espionage and foreign intelligence objectives.
Autonomous Vehicle Technology Vulnerable to Road Object Spoofing and Vanishing Attacks
Researchers have demonstrated the potentially hazardous vulnerabilities associated with the technology called LiDAR, or Light Detection and Ranging, many autonomous vehicles use to navigate streets, roads and highways. The researchers have shown how to use lasers to fool LiDAR into “seeing” objects that are not present and missing those that are – deficiencies that can cause unwarranted and unsafe braking or collisions.
