The idea is some kind of alien communication device, which periodically receives communications through an untraceable, uninterceptable method (quantum entanglement?) and said transmissions contain blueprints for building very useful, advanced technology, except each one has a very carefully hidden flaw seemingly designed to make the design backfire and harm humanity. For example, a blueprint for an efficient, non-polluting energy generator has a flaw that will make it explode and cover most of the Earth in radiation. A blueprint for a cure for cancer has a flaw that will cause it mutate into a deadly worldwide pandemic.
Every time they get a new design, they keep searching for a flaw in it but often times they can't find one, so they just have to assume it's there but hidden, but it still tempts people to make these things. Etc.
