• Executing Meterpreter on Windows 10 and Bypassing Antivirus

    June 26, 2018, Esteban Rodriguez, Consultant, Coalfire Labs, Coalfire

    One of my Labs colleagues recently published an article on the Coalfire Blog about executing an obfuscated PowerShell payload using Invoke-CradleCrafter. This was very useful, as Windows Defender has upped its game lately and is now blocking Metasploit’s Web Delivery module.

  • How I Found CVE-2018-8819: Out-of-Band (OOB) XXE in WebCTRL

    June 11, 2018, Darrell Damstedt, Senior Consultant, Coalfire Labs, Coalfire

    I like to do bug bounties from time  to time, mostly when I am sacrificing sleep once the kids are finally out cold.  This seemed like a worthy experience to document. Let me just start by saying I  don't plan on going into the whole recon bits too deeply here. Maybe I will someday if I ever have enough time to give the topic the justice it deserves.

    June 01, 2018, Michael Pitcher, Vice President, Technical Cyber Services, Coalfire Federal

    I recently spoke at the Cloud Security Alliance’s Federal Summit on the topic “Continuous Monitoring / Continuous Diagnostics and Mitigation (CDM) Concepts in the Cloud.” As government has moved and will continue to move to the cloud, it is becoming increasingly important to ensure continuous monitoring goals are met in this environment. Specifically, cloud assets can be highly dynamic, lacking persistence, and thus traditional methods for continuous monitoring that work for on-premise solutions don’t always translate to the cloud.
