Why it matters
Shadow AI agents that inherit a user's full permissions can silently read and exfiltrate sensitive files across an endpoint without any human checkpoint, expanding the exposure defenders must contain.
Jetico's blog post argues that AI agents installed on employee endpoints inherit the user's permissions, turning "shadow AI" from a copy-paste data-leak problem into an autonomous access problem where an unapproved agent can read every file the user's account can open. The post cites Traficom (Finnish Transport and Communications Agency) guidance on agent permissions and advocates default-deny, file-level access control as a mitigation.
