Although the incident has not affected operations nor had any material financial impact, Aztech says has notified the appropriate law enforcement authority and that it is looking at appointing third-party forensic advisors to help investigate the incident.
The company is also seeking advice from industry experts to further strengthen its overall cybersecurity.
The cybersecurity incident announced by Aztech Global is the latest in a spate of ransomware attacks reported by Singapore-listed companies since the start of the year.
In January, IPS Securex Holdings, ES Group (Holdings) and RE&S Holdings made separate announcements of ransomware attacks on their servers.
