Detection and response for the actively exploited ProxyShell vulnerabilities
ProxyShell vulnerabilities (CVE-2021-31207, CVE-2021-34473, CVE-2021-34523) in Microsoft Exchange servers are being actively exploited by chaining multiple flaws to gain network access. Threat actors leverage these compromises for post-exploitation activities including ransomware deployment. Elastic Security has identified indicators of compromise (IoCs) matching industry-observed attack patterns.
Why it matters: Unpatched Exchange server operators face immediate risk of network compromise and ransomware infection; detection and patching of these three vulnerabilities is critical today.
