According to Homeland Security secretary Kirstjen Nielsen, hacking attacks are mounting against U.S. energy companies.
Electronic sensors and other monitoring devices are an integral part of tracking data from oil and gas wells and pipelines. Complex computer algorithms are constantly adjusting the flows of everything from oil and natural gas to electrical power, with automatic valves in place that can shut down flow at a moment's notice. However, these are vulnerable to electronic sabotage, as was evidenced by an attack against 5 energy companies in March, 2018.
This and other cyberattacks led this past week to Nielsen’s announcement that guarding the sector will be a top priority for a new cybersecurity effort including a "major" cybersecurity exercise to be held later this year.
