About this actor

[Leviathan Australian Intrusions](https://attack.mitre.org/campaigns/C0049) consisted of at least two long-term intrusions against victims in Australia by [Leviathan](https://attack.mitre.org/groups/G0065), relying on similar tradecraft such as external service exploitation followed by extensive credential capture and re-use to enable privilege escalation and lateral movement. [Leviathan Australian Intrusions](https://attack.mitre.org/campaigns/C0049) were focused on exfiltrating sensitive data including valid credentials for the victim organizations.(Citation: CISA Leviathan 2024)
