Australian gold mining firm Evolution Mining on Monday disclosed a ransomware attack that impacted its IT systems last week.
In a filing (PDF) with the Australian Securities Exchange (ASX), the company said that the attack was identified on August 8 and that it believes it has been contained.
“The incident has been proactively managed with a focus on protecting the health, safety and privacy of people, together with the company’s systems and data,” Evolution Mining said.
The company also revealed that it has been working with external cyber forensic experts to investigate the attack and that the Australian Cyber Security Centre was informed of the incident.
“The company does not anticipate any material impact on operations,” Evolution Mining noted in the ASX announcement.
The company did not provide specific details on the ransomware gang behind the attack and SecurityWeek has not seen any known groups claiming responsibility for the incident.
The ransomware attack on Evolution Mining comes roughly two months after the BianLian ransomware gang published on its Tor-based leak site data allegedly stolen from the Australian rare-earth metals producer Northern Minerals.
The company confirmed at the time that corporate, operational, and financial data, personal information pertaining to current and former personnel, and some shareholder information was compromised in the attack, but said the incident did not have a material impact on its operations.
While ransomware groups are financially motivated, rare earth mining companies in Australia were previously targeted by Chinese hackers as part of influence campaigns.
