We’re excited to announce another keynote speaker for AUSCERT2025 – Chris Rock! No, not the comedian, but the renowned cyber mercenary! With 30 years of experience across the Middle East, US, and Asia, Chris has worked with both government and private organisations. He is the Chief Information Security Officer and co-founder of SIEMonster and has presented three times at the world’s largest hacking conferences. Want to learn more?

Oracle has rejected claims that its cloud systems were compromised after a cyber criminal advertised the alleged theft of sensitive data from Oracle Cloud. The attacker claimed to have exploited a vulnerability in Oracle’s Single Sign-On (SSO) login servers, but Oracle denied this, stating no breach occurred and that the leaked credentials were unrelated to Oracle Cloud.
The situation intensified when the threat actor released a 10,000-line sample of the purportedly stolen data, apparently to substantiate their claim of exfiltrating 6 million records from Oracle Cloud. Bleeping Computer contacted some of the alleged victim organisations, some of whom reportedly validated the stolen information was theirs.
AUSCERT has issued a Critical Member Security Information Notification to potentially impacted members. We are actively monitoring the situation and will continue to update members as it unfolds. Despite these developments, Oracle maintains there has been no breach and is proceeding with its investigation.

The maintainers of Kubernetes have released patches for four critical vulnerabilities in the Ingress NGINX Controller, affecting 6,500, or 41%, of all Internet-facing container orchestration clusters, including those used by several Fortune 500 companies.
The vulnerabilities allow a remote, unauthenticated attacker to execute arbitrary commands in affected environments and completely take over Kubernetes clusters, according to researchers at Wiz who discovered the flaws.

Despite Oracle denying a breach of its Oracle Cloud federated SSO login servers and the theft of account data for 6 million people, BleepingComputer has confirmed with multiple companies that associated data samples shared by the threat actor are valid. Last week, a person named ‘rose87168’ claimed to have breached Oracle Cloud servers and began selling the alleged authentication data and encrypted passwords of 6 million users
ASB-2025.0050 – AUSCERT Bulletin Service – Oracle Cloud breach
AUSCERT released an advisory regarding an alleged Oracle Cloud breach, where a threat actor claims to have stolen 6 million sensitive records. Oracle has denied the breach despite data samples appearing legitimate. The impact remains unclear, and mitigation measures should be evaluated based on the organisation’s policies.
ESB-2025.1921 – GitLab Community and Enterprise Editions: CVSS (Max): 8.7
GitLab issued a security advisory urging users to upgrade to versions 17.10.1, 17.9.3, or 17.8.6 to address multiple vulnerabilities, including two high-severity XSS flaws (CVSS 8.7): CVE-2025-2255, which allows XSS via merge-request error messages, and CVE-2025-0811, caused by improper rendering of certain file types, both affecting versions prior to 17.8.6, 17.9.3, and 17.10.1.
