BERLIN (Reuters) - A series of cyber attacks attributable to the Russian military intelligence service GRU targeted Germany's governing Social Democrats as well as the country's logistics, defence, aerospace and IT sectors, the interior ministry said on Friday.

APT 28 - the group that orchestrated the attacks in 2022 and reports to the GRU - exploited a then-unknown vulnerability in Microsoft Outlook over a longer period of time in order to compromise email accounts, the ministry said.
