Interpol's Operation Synergia III dismantles international cybercrime networks through unprecedented global cooperation, resulting in 94 arrests and the sinkhole of 45,000 malicious IP addresses across 72 countries.
Interpol has announced the results of Operation Synergia III, its third major global cybercrime crackdown, which has led to 94 arrests, 110 ongoing investigations, and the takedown of over 45,000 malicious IP addresses across 72 countries.
The operation, which ran from July 18, 2025, to January 31, 2026, targeted sophisticated cybercrime networks involved in phishing, romance scams, credit card fraud, and other digital crimes. Law enforcement agencies from 72 countries participated in the initiative, marking a significant expansion from the 52 countries involved in the first Operation Synergia in 2023.
Bangladesh: A Major Hub of Cybercrime Activity
Bangladesh emerged as a focal point of the operation, with local authorities arresting 40 suspects and seizing 134 devices for further examination. These individuals were linked to a wide range of cybercrime schemes, including loan and employment scams, identity theft, and credit card fraud.
The scale of criminal activity in Bangladesh highlights how certain regions have become hubs for organized cybercrime operations, often due to a combination of technical expertise, economic factors, and the availability of sophisticated tools.
Togo: Specialized Criminal Networks
In Togo, police contributed to ten arrests, targeting members of a fraud ring operating within a residential area. Interpol noted that each suspect had different areas of specialization within the criminal organization.
Some suspects focused on technical aspects, such as compromising social media accounts and developing malware, while others specialized in social engineering techniques, running romance scams and sextortion schemes. This division of labor demonstrates the professionalization of cybercrime operations, where criminals develop specific expertise much like legitimate businesses.
Macau: Massive Phishing Infrastructure Takedown
Authorities in Macau were responsible for the vast majority of IP takedowns, identifying and neutralizing more than 33,000 phishing and fraud websites. These malicious sites impersonated legitimate organizations including banks, government departments, and payment services.
Victims who interacted with these fake websites had their personal and financial information stolen. The fraud websites primarily consisted of fake online casinos that encouraged victims to deposit money into accounts they could never actually use for gambling.
The Power of International Cooperation
Neal Jetton, Interpol's director of the cybercrime directorate, emphasized 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."
Private sector partners including Group-IB, S2W, and Trend Micro provided crucial technical support. Robert McArdle, director of cybercrime research at Trend Micro's TrendAI unit, explained the value of this collaboration: "Behind every malicious server or phishing kit sits a wider criminal ecosystem that needs to be mapped and understood before arrests become possible."
Evolution of Operation Synergia
The operation has grown significantly since its inception. The first wave in 2023 resulted in 1,300 IP seizures across 52 countries. By the third iteration, these numbers had grown to over 45,000 IP addresses and 72 participating countries.
This expansion reflects both the increasing scale of global cybercrime and the growing recognition among law enforcement agencies of the need for coordinated international responses to digital threats.
The Criminal Ecosystem
Operation Synergia III demonstrates how modern cybercrime operates as a sophisticated, interconnected ecosystem. Criminal networks now employ specialized roles, develop advanced technical capabilities, and target victims across international borders with coordinated campaigns.
The success of this operation shows that while cybercrime continues to evolve and become more professionalized, international law enforcement cooperation can effectively disrupt these criminal networks when properly resourced and coordinated.

The scale of Operation Synergia III, with its 94 arrests and 45,000 IP takedowns, represents one of the largest coordinated cybercrime enforcement actions in history. As digital crime continues to evolve, such international cooperation will likely become increasingly essential for protecting individuals and organizations from sophisticated cyber threats.
