In the example, Moore's videos were stored with "ZXSecurity17Cam@" as the encryption key, something that would be easily cracked by anyone really wanting your footage.Moore says that Eufy has already patched some of the issues, making it impossible to verify stored cloud data status, and has issued the following statement: "Unfortunately (or fortunately, however you look at it), Eufy has already removed the network call and heavily encrypted others to make it almost impossible to detect; so my previous PoCs no longer work.Eufy says that "although our eufy Security app allows users to choose between text-based or thumbnail-based push notifications, it was not made clear that choosing thumbnail-based notifications would require preview images to be briefly hosted in the cloud.Eufy says it's making the following changes to improve communication on this matter: We are revising the push notifications option language in the eufy Security app to clearly detail that push notifications with thumbnails require preview images that will be temporarily stored in the cloud.I have sent Eufy several follow-up questions asking about further issues found in Paul Moore's proof of concept below and will update the article once those are answered."
