No cases have been reported in Malaysia so far, following the cyber attack on computer systems particularly in Europe.

The National Security Council in a statement said monitoring by its National Cyber Coordination and Command Centre (NC4) had determined so.

"Malaysia could potentially be attacked and we are on the alert," it said.

The council said advisories had been circulated to Critical National Information Infrastructure agencies on taking protective measures.

"Computer users are also advised to update their Windows operating system, antivirus software, make copies of their important files and not to open suspicious emails," it added.

Various critical sectors and services such as government, energy, transportation, communications, health and banking in countries such as Ukraine, Russia, Britain, Spain, France, Italy, United States, Denmark, Poland, Norway, India and Australia were reported to have been targeted. - BERNAMA
