In a significant move to disrupt state-sponsored cyber threats, U.S. authorities and Microsoft have seized dozens of internet domains tied to Russian intelligence-backed hackers. These domains were part of an extensive spear-phishing campaign targeting U.S. government computers and officials, along with allied nations and democratic institutions. The operation underscores the ongoing efforts to combat cyber espionage and protect sensitive information from foreign adversaries.
Seizure of 41 Internet Domains: A Strategic Cybersecurity Move
On Thursday, Deputy Attorney General Lisa Monaco announced the successful seizure of 41 internet domains used by Russian-affiliated hackers as part of the U.S. Department of Justice’s broader cyber strategy. This strategy aims to deter and disrupt malicious cyber activities orchestrated by state-sponsored actors. Monaco emphasized that these seizures reflect the U.S. government’s commitment to leveraging all available tools to counter cyber threats.
These domains, seized by federal prosecutors, were reportedly operated by hackers linked to Russia’s Federal Security Service (FSB) and its Callisto Group. The Callisto Group, also known by its aliases Star Blizzard, SEABORGIUM, and Cold Driver, has been associated with cyberattacks aimed at infiltrating government systems and accessing confidential information. Their targets have included high-profile entities such as NATO officials, Ukrainian government figures, think tank researchers, and journalists.
Callisto Group’s Sophisticated Spear-Phishing Campaign
The Justice Department revealed that the Callisto Group hackers were utilizing the seized domains as part of an advanced spear-phishing campaign. Spear-phishing, a type of cyberattack that relies on social engineering, involves sending deceptive emails to individuals under the guise of legitimate communication from trusted sources. The goal is to trick recipients into revealing sensitive information, such as login credentials or other personal data.
According to Monaco, the Russian-backed hackers exploited these domains to steal sensitive information from U.S. citizens, particularly those involved in critical governmental functions. “The Russian government ran this scheme to steal Americans’ sensitive information, using seemingly legitimate email accounts to trick victims into revealing account credentials,” Monaco stated.
Microsoft’s Role in Combatting Russian Cyber Threats
Alongside the federal government’s actions, Microsoft took legal steps to further dismantle the cyber network operated by the Callisto Group. The tech giant filed a civil lawsuit seeking to seize 66 additional internet domains controlled by the hackers. In a statement, Microsoft disclosed that it had been authorized to take control of these domains, which were being used to target its customers in ongoing cyberattacks.
Since January 2023, Microsoft has identified 82 targeted attacks by the Callisto Group, averaging one attack per week. The company noted that these attacks focused on over 30 civil society organizations, including non-governmental organizations (NGOs), think tanks, and journalists—entities that play a crucial role in supporting democratic processes. The hackers’ operations, often unnoticed by their victims, have led to stolen credentials and compromised accounts, disrupting the work of these organizations and sowing fear among their members.

A Persistent Threat to Democracy
Microsoft referred to the Callisto Group, or Star Blizzard, as a “persistent” adversary, highlighting the group’s ability to repeatedly compromise victims through well-executed spear-phishing attempts. The hackers’ techniques involve sending carefully crafted messages that deceive recipients into believing the communications are from trusted sources, leading them to unknowingly disclose sensitive information.
These cyberattacks have wide-ranging consequences, including straining the resources of targeted organizations, hampering their operations, and fostering an atmosphere of fear and uncertainty. Such actions directly hinder democratic participation by undermining the trust and security of individuals and institutions vital to democratic processes.
Previous Sanctions and Indictments Against Callisto Group Members
The latest domain seizures come on the heels of a previous crackdown on the Callisto Group. In December 2023, the United States and Britain jointly announced sanctions and indictments against two Russian hackers tied to the FSB’s Callisto Group. The indictment detailed the group’s activities, which involved targeting U.S. intelligence officials, employees of the Departments of Defense and State, contractors, and Department of Energy facilities. The group’s cyber operations spanned from October 2016 to October 2022, demonstrating the long-standing nature of the threat they pose.
Conclusion: An Ongoing Battle Against Cyber Espionage
The seizure of these 41 domains represents a critical victory in the broader fight against state-sponsored cyber espionage. By disrupting the Callisto Group’s spear-phishing campaigns, U.S. authorities and Microsoft have dealt a blow to one of Russia’s most persistent cyber adversaries. However, as both governments and private sector partners acknowledge, the fight against sophisticated cyber threats like those posed by the Callisto Group is far from over. Collaborative efforts will continue to safeguard democratic institutions, protect sensitive data, and ensure that malicious actors cannot operate unchecked in cyberspace.
