Germany Says Hackers Infiltrated Main Government Network

BERLIN — Hackers using highly sophisticated software penetrated the German government’s main data network, a system that was supposed to be particularly secure and is used by the chancellor’s office, ministries and the Parliament, government officials have said.

German news outlets, citing security sources, have widely blamed a Russian hacking group backed by the Russian government — either one called Snake, or another known as APT28, or Fancy Bear. But Berlin has not publicly said who was behind the attack.
