| Risk | Description | |------|-------------| | | A disgruntled employee can extract corporate Wi-Fi passwords and share them externally. | | Post-Exploitation | Malware or a remote access trojan (RAT) can execute this command to harvest credentials. | | Shared Machines | In libraries or labs, one user can retrieve passwords saved by another user on the same machine. | | Physical Access | An attacker with brief access to an unlocked workstation can extract all stored Wi-Fi credentials in seconds. |
