Domestic Extremists Have Plotted to Disrupt US Power Grid, DHS Bulletin Warns

CBS News reports that foreign cyberattackers aren't the only potential threat to America's electrical power grid:

Domestic violent extremists have been planning to try to disrupt the U.S. power grid and will probably keep doing so, according to a Department of Homeland Security intelligence bulletin shared with law enforcement agencies and utility operators Monday and obtained by CBS News. 'Domestic violent extremists have developed credible, specific plans to attack electricity infrastructure since at least 2020, identifying the electric grid as a particularly attractive target given its interdependency with other infrastructure sectors,' the bulletin reads. It warns that extremists 'adhering to a range of ideologies will likely continue to plot and encourage physical attacks against electrical infrastructure.'

Still, the bulletin notes that, 'Absent significant technical knowledge or insider assistance, small scale attacks are unlikely to cause widespread, multi-state power loss but may result in physical damage that poses risks to operations or personnel.'
