2021-009: Malicious actors deploying Gootkit Loader on Australian Networks   Advisory

Aug 27, 2021 - From April 2021, the Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC) has received an increase in reporting of malicious actors targeting Australian networks with Gootkit JavaScript (JS) Loaders. Open-source reporting confirms that Gootkit JS Loaders are a precursor to several malware families traditionally used for cybercrime, notably, Gootkit, REvil ransomware, Kronos, or CobaltStrike. The ASD’s ACSC is providing this information to enable organisations to undertake their own risk assessments and take appropriate actions to secure their systems and networks. The ASD’s ACSC will update this advisory if more information becomes available.
