The officials of Bundestag, lower house of German parliament, on May 15 confirmed that its IT system has been attacked by hackers.
Ernst Hebeker, spokesperson at the Bundestag, said in Berlin, that the hackers targeted on the IT systems of the parliament.
He added that the experts, associated with Bundestag administration and the government office for Information Technology Security (BSI) are working to fend off the hackers.
According to Spiegel Online, the IT specialists from the parliament noticed several days ago that someone was trying to gain access to the Bundestag’s internal network in a serious attack.
However, there is no information about, whether any computers containing sensitive information were penetrated or not.
MPs and their assistants from several parties, who were already warned about the attack on Friday morning, were told that the network would be shut down in the afternoon (May 15).
The Bundestag’s computers were temporarily switched off, including systems containing information on the inquiry into spying by the U.S. National Security Agency (NSA) in Germany.
Earlier in January, the Bundestag and Chancellery were attacked from hackers which resulting both institutions paralysed for several hours.
According to the officials, a pro-Russian hacker group in Ukraine claimed responsibility.
