Joiner

The subject enters the organization with a pre-formed intent to exploit their position, gain access to sensitive data, or otherwise contravene internal policies. Unlike most new hires (who align with organizational values and security expectations) joiner-motivated subjects present a latent threat from day one, often embedding their intent within the onboarding process, role selection, or early-stage access decisions.

 

Joiner motivation may stem from pre-existing agendas including espionage, competitive intelligence, ideology, or personal financial gain. The subject may deliberately target roles that offer visibility into proprietary systems, customer data, intellectual property, or internal governance. Their background may be curated to pass pre-employment screening, and they may arrive with pre-established exfiltration methods or operational security tactics designed to avoid detection.

 

Risk is highest during the early tenure period, when access is granted but behavioral baselines are not yet established. These subjects often exploit onboarding leniency, trust-building phases, and provisioning delays, taking advantage of initial low scrutiny to stage preparatory actions or initiate incremental infringement.

 

Investigators should treat joiner cases with heightened sensitivity. Detection may implicate upstream controls such as hiring processes, third-party screening providers, or internal referral pathways. Missteps in attribution may also generate legal or reputational risk, particularly if the subject was placed in a position of elevated trust.
