On October 29, 2025, the threat actor group published an announcement claiming to have compromised the organization's data, marking a significant development in the ongoing threat landscape facing the manufacturing sector.

The claimed attack and extortion tactics

The Qilin ransomware group, which has been active since 2022 and targets various sectors, released its announcement on October 29, 2025. According to the group's claim, they have successfully breached Malibu Boats Australia. This listing indicates that the group is employing double extortion tactics to threaten the organization.

Double extortion is a common method used by modern ransomware groups.

The threat actors then threaten to leak this stolen data on public or private leak sites if the ransom demands are not met. This approach increases the pressure on the victim, as the threat of public exposure can cause significant reputational and regulatory damage, even if the organization has robust backups to restore its operational systems.
