41 servers seized and 32 suspects arrested during Operation Secure.
More than 20,000 malicious IP addresses or domains linked to information stealers have been taken down in an INTERPOL-coordinated operation against cybercriminal infrastructure.
During Operation Secure (January – April 2025) law enforcement agencies from 26 countries worked to locate servers, map physical networks and execute targeted takedowns.
Ahead of the operation, INTERPOL cooperated with private-sector partners Group-IB, Kaspersky and Trend Micro to produce Cyber Activity Reports, sharing critical intelligence with cyber teams across Asia. These coordinated efforts resulted in the takedown of 79 per cent of identified suspicious IP addresses.
Participating countries reported the seizure of 41 servers and over 100 GB of data, as well as the arrest of 32 suspects linked to illegal cyber activities.
Infostealer malware is a primary tool for gaining unauthorized access to organizational networks. This type of malicious software extracts sensitive data from infected devices, often referred to as bots. The stolen information typically includes browser credentials, passwords, cookies, credit card details and cryptocurrency wallet data.
Additionally, logs harvested by infostealers are increasingly traded on the cybercriminal underground and are frequently used as a gateway for further attacks. These logs often enable initial access for ransomware deployments, data breaches, and cyber-enabled fraud schemes such as Business Email Compromise (BEC).
Following the operation, authorities notified over 216,000 victims and potential victims so they could take immediate action - such as changing passwords, freezing accounts, or removing unauthorized access.
Vietnamese police arrested 18 suspects, seizing devices from their homes and workplaces. The group's leader was found with over VND 300 million (USD 11,500) in cash, SIM cards and business registration documents, pointing to a scheme to open and sell corporate accounts.
As part of their respective enforcement efforts under Operation Secure, house raids were carried out by authorities in Sri Lanka and Nauru. These actions led to the arrest of 14 individuals - 12 in Sri Lanka and two in Nauru - as well as the identification of 40 victims.
The Hong Kong Police analysed over 1,700 pieces of intelligence provided by INTERPOL and identified 117 command-and-control servers hosted across 89 internet service providers. These servers were used by cybercriminals as central hubs to launch and manage malicious campaigns, including phishing, online fraud and social media scams.
Neal Jetton, INTERPOL’s Director of Cybercrime, said:
“INTERPOL continues to support practical, collaborative action against global cyber threats. Operation Secure has once again shown the power of intelligence sharing in disrupting malicious infrastructure and preventing large-scale harm to both individuals and businesses.”
