Local User Credential Access

Local user credential access occurs when a synthetic subject can access credentials, tokens, keys, certificates, session files, or secrets stored in an employee’s workstation or development environment. This may include environment variables, command-line profiles, password manager access, cloud configuration files, package registry tokens, Secure Shell (SSH) keys, local application secrets, or local AI tools that can control the computer through the keyboard, mouse, browser, terminal, or graphical user interface.

This configuration creates an elevated exposure condition because the synthetic subject may discover and use credentials that were not intentionally granted to it. Local assistants, coding agents, terminal-capable agents, browser agents, or computer-use agents may inherit access to files, sessions, shells, profiles, clipboard contents, credential stores, or environment state containing sensitive credentials.

The primary risk is unintended credential use. A synthetic subject may read, copy, transmit, or apply local credentials to access systems beyond its intended scope, including source repositories, cloud environments, databases, internal tools, or production services.

Investigators should review endpoint file access, shell history, environment variables, credential stores, local configuration files, password manager events, source repository access, browser activity, clipboard activity, and tool runtime permissions. Particular attention should be given to AI tools with file-system access, terminal access, browser control, graphical user interface control, broad workspace access, or access to developer credential locations.

Investigative Relevance

Local user credential access is relevant because credentials stored for human convenience may become usable by a synthetic subject. This sub-section is especially relevant where local AI assistants, coding assistants, terminal agents, browser agents, or computer-use agents operate on employee workstations with access to the same local resources as the user.
