CTOS Digital's (KLSE:CTOS) cybersecurity system detected unauthorized access to an environment supporting its consumer business, according to a Wednesday filing with Bursa Malaysia.

The company said it immediately contained the affected environment and engaged an independent incident response team for a forensic investigation.

The assessment to date found that certain data files containing a limited subset of processed consumer information were accessed, while no other environments were impacted.

A subset of CTOS Digital's credit reporting services is temporarily unavailable, while other operations remain functional.

The incident has no material financial impact, the filing said.
