We'll dive into Active Directory domain persistence techniques focused on identifying attacks and reclaiming control over organizational domains after a breach. The presentation explores various advanced adversarial techniques such as credential theft on domain controllers, NTDS access, DCSync, and the creation of Golden and Diamond Tickets. It emphasizes the importance of detecting these methods to effectively triage and counteract them. The presentation highlights the need for organizations to be vigilant in monitoring and securing their domains, as adversaries continually seek innovative ways to maintain access, posing significant threats to data security. Additionally we'll cover post-compromise strategies, detailing the steps necessary for rotating domain secrets and enhancing Windows Security event auditing to better detect domain persistence activities. We'll provide a comprehensive guide on resetting and securing various account types, including machine, user, and service accounts, and emphasizes the criticality of rotating the KRBTGT account to prevent the abuse of Golden Tickets. This presentation will serve as a starting guide for critical technique detection generation and organizational recovery scenarios.
Affected OpenSSH versions:
— OpenSSH versions earlier than 4.4p1 are vulnerable to this signal handler race condition unless they are patched for CVE-2006-5051 and CVE-2008-4109.
— Versions from 4.4p1 up to, but not including, 8.5p1 are not vulnerable due to a transformative patch for CVE-2006-5051, which made a previously unsafe function secure.
— The vulnerability resurfaces in versions from 8.5p1 up to, but not including, 9.8p1 due to the accidental removal of a critical component in a function.
— OpenBSD systems are unaffected by this bug, as OpenBSD developed a secure mechanism in 2001 that prevents this vulnerability.
