MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection
Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.
T1213 Data from Information Repositories Collection
Adversaries may leverage information repositories to mine valuable information.
T1567 Exfiltration Over Web Service Exfiltration
Adversaries may use an existing, legitimate external Web service to exfiltrate data rather than their primary command and control channel.
Why these techniques?

CORS misconfiguration permits unauthorized cross-origin API access to PrivateGPT, facilitating collection of sensitive local data/documents (T1005, T1213) and exfiltration to attacker-controlled web services (T1567) via malicious JavaScript executed in the victim's browser.
