Group-IB, a creator of cybersecurity technologies for investigating, preventing, and fighting digital crime, has announced its contribution to INTERPOL-coordinated Operation Synergia III, a global cybercrime operation targeting malicious infrastructure used in phishing, malware, and ransomware campaigns.

The international operation took place between July 2025 and January 2026. It involved law enforcement agencies from 72 countries and territories. As a result, authorities arrested 94 people, while another 110 individuals remain under investigation. In addition, more than 45,000 malicious IP addresses and servers were taken down. Authorities also seized 212 electronic devices and servers linked to cybercriminal activity.

As part of the operation, Group-IB provided threat intelligence on phishing infrastructure and malicious servers used by cybercriminal networks. The company leveraged its adversary-centric threat intelligence to share data on phishing domains, hosting infrastructure supporting these campaigns, and servers distributing malware such as infostealers. This information helped investigators identify and disrupt cybercriminal infrastructure across multiple jurisdictions.

“Cybercriminal groups rely on complex infrastructure to scale phishing and malware operations globally,” said Dmitry Volkov, CEO of Group-IB. “Operation Synergia III demonstrates how close cooperation between law enforcement agencies and private-sector partners can significantly disrupt these networks. By sharing intelligence on malicious infrastructure and attacker tactics, Group-IB remains committed to supporting global efforts to dismantle cybercrime operations and protect organizations and individuals worldwide.”

Meanwhile, Neal Jetton, Director of the Cybercrime Directorate at INTERPOL, highlighted the importance of global collaboration. “Cybercrime in 2026 is more sophisticated and destructive than ever before, but Operation Synergia III stands as a powerful testament to what global cooperation can achieve. INTERPOL remains at the forefront of this fight, uniting law enforcement agencies and private sector experts to dismantle criminal networks, disrupt emerging threats and protect victims around the world,” he said.

Operation Synergia III targeted a wide range of cybercriminal activities. These included fraudulent websites, phishing campaigns, malware distribution, ransomware attacks, romance scams, and credit card fraud schemes. Investigations revealed thousands of malicious domains and servers used by criminals. These platforms were designed to impersonate financial institutions, government services, and legitimate organizations in order to steal personal and financial data from victims.

Authorities also uncovered several large-scale criminal schemes during the operation. For example, in Macau, investigators identified more than 33,000 phishing and fraudulent websites. These websites impersonated casinos, banks, and government services to steal personal and payment information.

Similarly, in Togo, police dismantled a fraud ring involved in social media account hacking, romance scams, and extortion. Criminals impersonated victims online and manipulated their contacts into transferring money.

Meanwhile, in Bangladesh, authorities arrested 40 suspects connected to multiple cybercrime schemes. These included loan scams, job fraud, identity theft, and credit card fraud. Investigators also seized more than 130 electronic devices used in the operations.

Group-IB maintains long-standing partnerships with international law enforcement organizations, including INTERPOL, Europol, and AFRIPOL. Through these collaborations, the company provides threat intelligence and investigative support to global cybercrime investigations.

Furthermore, Group-IB leverages predictive threat and fraud intelligence capabilities alongside its adversary-centric approach to tracking cybercriminal infrastructure and tactics. This approach helps transform technical indicators into actionable intelligence for investigators.

As cybercrime continues to grow in scale and sophistication, public-private partnerships remain essential to dismantling criminal infrastructure and strengthening global cyber resilience. In this effort, Group-IB will continue working with international law enforcement agencies to identify emerging cyber threats and disrupt criminal networks worldwide.
