KUALA LUMPUR (March 12): Bursa Malaysia Bhd (KL:BURSA) said on Thursday cybersecurity incidents at a few brokers had no impact on the exchange’s networks, platforms or infrastructure.

“These reported incidents are limited to those affected brokers’ respective systems, with no impact on the exchange’s networks, platforms or infrastructure,” the exchange operator said in a statement. “All trading and market operations continue to function as usual.”

The statement follows The Edge’s report about trading platform disruption affecting several brokerages since last week. At least three were affected though one of the brokers has since resumed service after suspending online trading for two days last week and mandating password change for all clients.

The problem was traced to trading platform vendor, one of the people familiar with the matter told The Edge.

The affected brokers have contained the incidents through immediate isolation of the component and implementation of their internal incident response controls, Bursa said on Thursday.

“Immediately upon receiving these reports, we activated established cybersecurity response protocols and coordinated closely with the affected brokers to ensure rapid containment and remediation,” the exchange said.

The brokers are conducting full forensic investigations and report through the bourse's supervisory channels, Bursa said, noting that there has been no evidence of unauthorised trading activity or financial loss.

Bursa said it has also directed all brokers and selected vendors to conduct a full review of their systems. “We have issued advisories and provided briefings to reinforce vigilance and ensure that these parties continue strengthening their cybersecurity safeguards,” the exchange added.
