A six-month cyberattack against the German parliament in 2015 was organized by the Russian government, according to a report in the newsweekly Der Spiegel.
The magazine reported on January 30 that German authorities are certain that a Trojan virus attack against the Bundestag's computer network in the first half of 2015 was carried out by a Russian-government-funded hacker group known by the names Sofacy and APT28.
The attack shut down the network for several days and compromised a large amount of German government data.
A senior German security official who was not named told the magazine Berlin believes the attack is "clearly" linked to "a Russian military intelligence service."
He added that the attack followed a similar pattern to other cyberattacks against Germany and other NATO countries.
