As a consequence of the cyber-attack, the travel data of the US Department of Defense personnel, servicemen and civilians was stolen. According to a U.S. official familiar with the matter, the breach could have affected as many as 30,000 workers, but that number may grow as the investigation continues. The breach could have happened some months ago but was only recently discovered.
The U.S. Government Accountability Office in its Tuesday report said the Pentagon has worked to ensure its networks are secure, but only recently began to focus more on its weapons systems security. The audit, conducted between September 2017 and October 2018, found that there are "mounting challenges in protecting its weapons systems from increasingly sophisticated cyber threats."
Reportedly, the military of the U.K. considered the possibility of the holding of the extensive cyber-attack against Russia, in case, if the Russian Federation “assaults West countries”.
Earlier, the Netherlands announced the prevention of Russia’s cyber-attack at the Organisation for the Prohibition of Chemical Weapons (OPCW) and accused Russian Main Intelligence Directorate officers (GRU) of trying to get the information from the international investigation of the MH17 tragedy.
Also, Germany has joined the British and the Dutch authorities in accusing Russia of instigating massive international cyber-attacks.
