Russian APT28 military hackers used Microsoft Outlook zero-day exploits to target multiple European NATO member countries, including a NATO Rapid Deployable Corps.
The Russian hackers are also tracked as Fighting Ursa, Fancy Bear, and Sofacy, and they've been previously linked to Russia's Main Intelligence Directorate, the country's military intelligence service.
"Using a zero-day exploit against a target indicates it is of significant value. It also suggests that existing access and intelligence for that target were insufficient at the time," Unit 42 said.
In October, the French cybersecurity agency disclosed that Russian hackers used the Outlook security flaw to attack government bodies, corporations, educational institutions, research centers, and think tanks across France.
