Fairfield Council Obtains Injunction Against Unknown Threat Actors in Ransomware Incident

In October 2025, Fairfield Council, a local government body in western Sydney, Australia, experienced a ransomware attack where unknown threat actors illegally accessed its servers. The compromised systems contained sensitive data, including personal, financial, and property information of councillors, ratepayers, residents, and staff. The council has since obtained an injunction against the unidentified attackers and is communicating with them via Dropbox links in a chatroom. No specific ransomware strain, technical attack vectors, or CVE identifiers were disclosed in the incident. The breach remains under investigation, with no confirmation of data exfiltration or ransom demands publicly detailed.
