To say the HAFNIUM has caused a bit of pandemonium the past week or so is a bit of an understatement. The 0-day vulnerability is being actively used by nefarious individuals and groups to access. HAFNIUM has previously compromised victims by exploiting vulnerabilities in internet-facing servers, and has used legitimate open-source frameworks, like Covenant, for command and control. Once they've gained access to a victim network, HAFNIUM typically exfiltrates data to file sharing sites like MEGA. Affected versions: The vulnerabilities affect Exchange Server versions 2013, 2016, and. The 0day exploit HAFNIUM was available for exchange 2010 - 2019, so every exchange admin who published exchange was vulnerable. But that is not the only problem.

However, it is critical to keep the Windows Server and Exchange version the same on the new server to avoid issues Script to Check for Exploits. Test-ProxyLogon.ps1 is a PowerShell script written by Microsoft (downloadable from GitHub - updated March 5) to check servers for signs of exploits from the vulnerabilities reported in CVE-2021-26855, 26858, 26857, and 27065. If you're worried that your servers might have been compromised, you can run the script and work with Microsoft support if anything. There are scripts available that use nmap to check whether your Exchange server is vulnerable for the HAFNIUM zerodays or not after patching Exchange. I've never used nmap before. The script says that if you're vulnerable you get the following output: I get a relatable output, but not exactly the same: nmap -p 443 --script http-vuln-cve2021. The Hafnium purported nation-state attacks have quickly shifted to other threat actors who are using the zero-day Exchange Server exploits to but it doesn't check for compromises or take.

In these events you can observe that the HTTP response code is 404, signalling the WebShells do not exist on this particular server.
