In related politics news, President Donald Trump renominated Sean Plankey for the role of director at the cyber security agency CISA, having previously won the approval of a US Senate committee in July 2025 but facing blockage by Republican Senator Rick Scott over a Coast Guard contract.

Separately, Reuters reports that Poland’s power grid faced its largest cyberattack in years in late December 2025, targeting communications between renewable energy installations and distribution operators; officials said the operation was repelled and did not cause a blackout, with Russian hackers described as the likely perpetrators.
