A pro-Russian hacker group, Noname057, has claimed responsibility for a distributed denial-of-service attack on the French national postal service, La Poste, causing central computer systems to go offline and disrupting package deliveries just days before Christmas. The attack, still ongoing as of Wednesday morning, impacted package tracking and online payments through La Banque Postale. Europol and the US Justice Department have taken actions against the group, known for targeting Ukraine and Ukraine-friendly nations.
