The spate of cyber-attacks which have affected a swathe of Australian companies in recent weeks has continued with TechnologyOne saying it had detected an unauthorised third-party access to its back-office systems.

TechnologyOne Limited is an Australian listed software company founded in 1987 and headquartered in Fortitude Valley in Brisbane, with other offices in the United Kingdom, New Zealand, South Pacific and Asia.

“TechnologyOne’s customer-facing SaaS platform is not connected to the Microsoft 365 system, and therefore, has not been impacted,” the firm said in an exchange filing.

The company suspended trading after the announcement, and said it has isolated the affected systems and will contact the impacted customers after an investigation is conducted.

The attack is only the latest in a series of high profile cyber incidents to affect the county of late.

Last month, Australia’s biggest casino operator Crown Resorts (pic below) said that a ransomware group had contacted the company, claiming that they had gained access to some files related to following a data breach at a file transfer service GoAnywhere.

Australian digital payments firm Latitude Group Holdings and intellectual property services provider IPH have also both reported data breaches.

Indeed, at least eight major companies have reported cyber-attacks in the last few months alone, the largest being health insurer Medibank and Optus, the local unit of Singapore Telecommunications.

Latitude said personal information, including copies of drivers’ licences and customer records, of around 328,000 customers held by two service providers were stolen.

IPH said it had detected unauthorised access to document management systems, which handle administrative documents, and some client documents and correspondence, at its head office and two member firms.
