This incident involves security flaws related to data handling and cloud storage, similar to previous incidents reported with other home security camera companies like Wyze, Ring, and Google [135243]. (b) The software failure incident has also happened at other organizations, including home security camera companies like Wyze, Ring, and Google, which have faced privacy infringements and security flaws in recent years. This incident with Eufy cameras sending data to cloud servers despite promises of local storage adds to the list of similar incidents across different companies in the industry [135243].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase is evident in the case of Eufy cameras. Despite the manufacturer's promise of "local storage for your eyes only," it was discovered that some Eufy cameras send data to Eufy's cloud servers, even when cloud storage is disabled. This design flaw allowed thumbnail images of videos, facial recognition data, and user identifier information to be sent to the cloud, contrary to the initial claims of local storage only [135243]. (b) The software failure incident related to the operation phase is highlighted by the fact that unencrypted live streams from Eufy cameras could be viewed using the open-source media player VLC without the need for authentication. This indicates a failure in the operation or security measures of the system, allowing unauthorized access to live streams [135243].
Boundary (Internal/External) within_system (a) The software failure incident related to Eufy cameras sending data to Eufy's cloud servers despite promises of "local storage for your eyes only" and not immediately removing data from the servers after deletion can be categorized as within_system failure. This is evident from the fact that the issue was exposed by security researcher Paul Moore, who provided evidence of the vulnerability within the system [135243]. Additionally, the response from Eufy mentioning revisions to push notifications and being more clear about the use of cloud for push notifications indicates that the failure originated from within the system and its design or implementation [135243].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case appears to be related to non-human actions. The failure was due to the Eufy cameras sending data to Eufy's cloud servers, including thumbnail images of videos, facial recognition, and user identifier information, despite the manufacturer's promise of "local storage for your eyes only" [135243]. This indicates that the failure was a result of the software design and functionality rather than direct human actions.
Dimension (Hardware/Software) hardware, software (a) The software failure incident related to hardware: - The article reports on a software failure incident involving Eufy cameras, specifically the Eufy Doorbell Dual and the EufyCam 3, sending data to Eufy's cloud servers despite promises of "local storage for your eyes only" [135243]. - Security researcher Paul Moore exposed the vulnerability by showing that thumbnail images of videos, facial recognition data, and user identifier information were sent to the cloud [135243]. - Additionally, Moore claimed that unencrypted live streams could be viewed using the open-source media player VLC without authentication [135243]. (b) The software failure incident related to software: - The software failure incident is primarily attributed to software issues, as the Eufy cameras were sending data to the cloud despite claims of local storage [135243]. - Eufy acknowledged the issue and mentioned revising the push notifications option language in the Eufy Security app to be clearer about the use of cloud for push notifications in their marketing materials [135243].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident in this case appears to be non-malicious.
