Today’s sophisticated adversaries are targeting not just isolated systems but entire interconnected domains — spanning endpoints, identities and cloud environments. These cross-domain attacks exploit fragmented security measures, leveraging compromised credentials, valid tools and gaps between siloed systems to infiltrate, escalate and execute their objectives with unprecedented speed and precision. The rise of cloud-native infrastructures, hybrid environments and remote work has expanded organizational attack surfaces while increasing complexity. In this eBook, CrowdStrike dissects the anatomy of cross-domain attacks, unveiling how adversaries navigate modern IT ecosystems to evade traditional defenses.
