MyIMMs Disruption Caused by Internal Technical Failure, Not Cyberattack, Says Home Ministry

PETALING JAYA : Malaysia’s Home Ministry has confirmed that the recent disruption affecting the Malaysia Immigration System (MyIMMs) was caused by an internal technical issue and not a cybersecurity attack.

The ministry said the system interruption, which lasted for more than three hours on Thursday morning, has since been fully resolved and operations have returned to normal.

In an official statement, the ministry stressed that there was no cybersecurity breach linked to the incident, adding that all immigration data remains secure and intact.

“The disruption did not involve any cybersecurity incident. No data breaches, loss, or corruption were recorded, and all information stored in the system remains secure and protected,” the statement said.

The ministry acknowledged that systems operating continuously with high transaction volumes require constant monitoring and improvements to maintain stability and resilience.

Authorities also stated that the incident has been taken into consideration as part of the ongoing transition from the current MyIMMs platform to the National Integrated Immigration System (MyNIISe), a next-generation immigration management system expected to fully replace MyIMMs by 2028.

According to the ministry, several enhancement measures are now being implemented by the Immigration Department to prevent similar disruptions in the future. These include increasing system storage and infrastructure capacity, strengthening real-time monitoring mechanisms, improving contingency recovery plans, and accelerating upgrade works under the MyNIISe project.

“The Immigration Department remains committed to ensuring that public service delivery and border management continue to operate smoothly, securely, and effectively,” the ministry added.

The ministry also apologised to travellers affected by the disruption and thanked the public for their patience and cooperation during the incident.

The system outage occurred at approximately 5am on Thursday and lasted until about 8.45am, causing severe congestion and long queues at several immigration checkpoints nationwide.

Immigration Department director-general Datuk Zakaria Shaaban previously said the disruption originated from a technical issue at the MyIMMs data centre. He also warned that similar disruptions could continue to occur until the MyNIISe system is fully operational.
