The Microsoft Digital Crimes Unit (DCU) has disrupted the activities of a China-based hacking group that we call Nickel. In documents that were unsealed today, a federal court in Virginia has granted our request to seize websites Nickel was using to attack organizations in the United States and 28 other countries around the world, enabling us to cut off Nickel’s access to its victims and prevent the websites from being used to execute attacks. We believe these attacks were largely being used for intelligence gathering from government agencies, think tanks and human rights organizations.

On December 2, Microsoft filed pleadings with the U.S. District Court for the Eastern District of Virginia seeking authority to take control of the sites. The court quickly granted an order that was unsealed today following completion of service on the hosting providers. Obtaining control of the malicious websites and redirecting traffic from those sites to Microsoft’s secure servers will help protect existing and future victims while telling us more about Nickel’s activities. This disruption will not prevent Nickel from continuing other hacking activities, but we do believe we have removed a key piece of the infrastructure the group has been relying on for this latest wave of attacks.

The Microsoft Threat Intelligence Center (MSTIC) has been tracking Nickel since 2016 and analyzing this specific activity since 2019. The attacks MSTIC observed are highly sophisticated and used a variety of techniques but nearly always had one goal: to insert hard-to-detect malware that facilitates intrusion, surveillance and data theft. Sometimes, Nickel’s attacks used compromised third-party virtual private network (VPN) suppliers or stolen credentials obtained from spear phishing campaigns. In some observed activity, Nickel malware used exploits targeting unpatched on-premises Exchange Server and SharePoint systems. However, we have not observed any new vulnerabilities in Microsoft products as part of these attacks.

Nickel has targeted organizations in both the private and public sectors, including diplomatic organizations and ministries of foreign affairs in North America, Central America, South America, the Caribbean, Europe and Africa. There is often a correlation between Nickel’s targets and China’s geopolitical interests. Others in the security community who have researched this group of actors refer to the group by other names, including “KE3CHANG,” “APT15,” “Vixen Panda,” “Royal APT” and “Playful Dragon.”

In addition to the U.S., the countries in which Nickel has been active include: Argentina, Barbados, Bosnia and Herzegovina, Brazil, Bulgaria, Chile, Colombia, Croatia, Czech Republic, Dominican Republic, Ecuador, El Salvador, France, Guatemala, Honduras, Hungary, Italy, Jamaica, Mali, Mexico, Montenegro, Panama, Peru, Portugal, Switzerland, Trinidad and Tobago, the United Kingdom and Venezuela.

Nation-state attacks continue to proliferate in number and sophistication. Our goal in this case is to take down malicious infrastructure, better understand actor tactics, protect our customers and inform the broader debate on acceptable norms in cyberspace.

No individual action from anyone in the industry will stem the tide of attacks we’ve seen from nation-states and cybercriminals working within their borders. We need industry, governments, civil society and others to come together and establish a new consensus for what is and isn’t appropriate behavior in cyberspace. We’re encouraged by recent progress. Last month, the United States and the European Union joined the Paris Call for Trust and Security in Cyberspace, the world’s largest multistakeholder confirmation of core cybersecurity principles with more than 1,200 endorsers. The Oxford Process has brought together some of the best legal minds to evaluate the application of international law to cyberspace. And the United Nations has taken critical steps to advance dialogue across stakeholders. It is our responsibility, and that of every entity with the relevant expertise and resources, to do whatever we can to help bolster trust in technology and protect the digital ecosystem.
