Our progress was affected enough that it forced us to focus on how to bypass CrowdStrike, rather than focusing on arguably more important aspects of the engagement such as identifying security misconfigurations and/or gaps in alerting and response. CrowdStrike Falcon gave us a difficult time by preventing several tools, techniques, and procedures (TTPs) from working that we had previous success with on prior engagements in terms of evading CrowdStrike Falcon. The beginning of this engagement was particularly frustrating as the client used CrowdStrike Falcon for the primary EDR solution in their environment. Please contact the 24/7 IT Help Desk if you have questions or need assistance transitioning your device to Defender for Endpoint.In this edition of Bypassing Defenses, we’ll highlight how we were able to bypass the Endpoint Detection and Response (EDR) solution Symantec Endpoint Protection on a recent Red Team engagement, enabling the execution of known malicious tools without detection or prevention. All devices still running a University-licensed version of Symantec will stop receiving virus definitions and security updates after this date, rendering them vulnerable to security threats. The limited extension of the University’s Symantec license expires on Monday, June 14, 2021. Symantec stopped providing virus definitions and security updates after the University’s license expired on June 13, 2020, except for a small number of devices that received a limited, one-year license extension.
Doing so ensures your devices remain protected against the latest security threats and ensures the University remains compliant with its licensing agreements. If you are still using Symantec Endpoint Protection, please upgrade to Microsoft Defender for Endpoint (formerly known as Defender ATP) on University-owned devices or an alternative antivirus solution on personal devices.
As we communicated last year, the University replaced Symantec Endpoint Protection with Microsoft Defender ATP as its enterprise antivirus solution last year.
