This report explains how visibility gaps from unmanaged or forgotten organizational assets (‘shadow IT’) — including edge appliances, exposed cloud storage, unmanaged OAuth tenants, developer secrets, and expired domains — are repeatedly exploited by attackers as low-monitored initial access and persistence vectors (enabling ransomware, data exfiltration, and identity-based persistence); it recommends continuous external footprint discovery and fast onboarding of telemetry to close the attacker/defender mapping gap.
