The Trump administration announced Thursday that Russia has been trying to hack into the U.S. energy grid.
Officials say that since at least early 2016, "Russian government cyber actors" have targeted multiple U.S. infrastructure sectors, including energy, nuclear, aviation and water.
U.S. officials pointed to a report released late last year about the Dragonfly 2.0 campaign, which the report blamed for targeting energy sectors in the U.S., Turkey and Switzerland.
News about Russia targeting U.S. infrastructure comes the same day the U.S. Treasury Department announced sanctions on 24 Russian entities and individuals.
Those sanctions were designed to respond, in part, to a massive 2017 cyberattack that targeted government, financial and energy sectors in Ukraine but expanded across Europe and into the U.S. Both the U.K. and U.S. previously blamed Russia for the attack.
