A federal court in the US state of Virginia has ruled that Microsoft may take over a number of sites used to attack targets in 29 countries.
According to Microsoft Blog the sites in question have been used by the Chinese hacker group Nickel, also known as APT15. The main targets have been human rights authorities and organizations.
Nickel has used stolen credentials and hacked vpn services to carry out attacks on Exchange servers that have not received the latest security updates.
In total, Microsoft has in recent years managed to put a stop to more than 10,000 sites used by hackers. The company has also managed to block 600,000 registrations of websites that would probably be used for cyber attacks.
