More than 1,000 malicious IP addresses in Singapore were taken down during a four-month operation led by Interpol targeting cybercriminal activities around the world, as per reports.
The joint operation, known as Operation Secure, took place between January and April 2025 and involved law enforcement agencies from 26 countries.
It focused on combating a specific type of malware called infostealers, which are designed to gain unauthorised access to organisational networks.

Infostealers are malicious tools that extract sensitive data from infected devices. These include browser credentials, passwords, cookies, credit card information, and cryptocurrency wallet data. According to Interpol, the stolen data, referred to as logs, is increasingly traded among cybercriminals and is often used to carry out further attacks. Such logs commonly serve as entry points for ransomware, data breaches, and other cyber-enabled fraud schemes.
Globally, Operation Secure resulted in the takedown of 20,000 malicious IP addresses and domains, the seizure of 41 servers, and the collection of more than 100 gigabytes of data, The Straits Times reported.

The operation also led to the arrest of 32 suspects. In Singapore, over 1,000 IP addresses were dismantled with the cooperation of the Cybercrime Command under the Criminal Investigation Department of the Singapore Police Force and the Cyber Security Agency of Singapore.
Interpol reported that more than 216,000 victims and potential victims were notified as part of the operation. These individuals were advised to take precautionary steps such as changing their passwords, freezing accounts, or removing unauthorised access to safeguard against further threats.
Singapore authorities stated that their involvement in the operation reflects an ongoing commitment to protecting individuals and businesses from the growing risks of cybercrime.
