A pro-Russian hacker group has come forward as the perpetrator of a DDoS attack on the French national postal service La Poste that took place on December 22, according to Reuters. The distributed denial-of-service attack took central computer systems at La Poste entirely offline and caused major disruptions in package deliveries just days before Christmas.Reuters reported that the cyberattack on La Poste was still not fully resolved as of Wednesday morning. While regular letters were not affected, postal workers were unable to track packages and online payments through La Banque Postale, the service's banking division, were also disrupted.The group, known as Noname057, has taken responsibility for or been accused of cyberattacks across the globe. Though attacks have occurred in over a dozen nations, the group has mostly targeted Ukraine as well as Ukraine-friendly nations.Europol, the EU's law enforcement agency, launched an extensive operation against the group this summer. The US Justice Department has also been involved in actions against the hacker group.This article originally appeared on Engadget at https://www.engadget.com/cybersecurity/pro-russian-hacker-group-claims-responsibility-for-ddos-attack-on-french-postal-service-140015323.html?src=rss
