Questions of DOGE’s large swipe of Social Safety information linger
Greater than a yr after operatives with the Elon Musk-led band of presidency destroyers known as the Department of Government Efficiency (or DOGE) swept by means of and dismantled federal companies from the within out, we’re nonetheless studying in regards to the information lapses that occurred below their watch.

Poland’s power grid was focused with computer-destroying malware late final yr, as was a Swedish thermal plant and a Norwegian dam that spilled entire swimming pools’ worth of water.
Then earlier this yr, Russian hackers focused Poland’s water treatment plants, displaying that Moscow’s hybrid warfare antagonism continues to increase past the digital realm.
