ACSC ALERT: Is Your SonicWall VPN an Open Door ...

On September 10, the Australian Cyber Security Centre (ACSC) issued a high-severity alert confirming that the Akira ransomware group is actively exploiting a critical SonicWall VPN vulnerability (CVE-2024-40766) to breach Australian businesses. The situation is more dangerous than it appears: patching the vulnerability is not enough to secure your network. Attackers are using a procedural loophole involving un-reset credentials to bypass the fix, leaving many organizations exposed despite their compliance efforts. This threat is amplified by Australia's new 2025 mandatory ransomware reporting laws, which can turn a technical breach into a regulatory and legal disaster. This analysis breaks down the technical risk, the severe business impacts, and the necessary steps to truly validate your defenses against this clear and present danger.
