I don’t find the scenario plausible. I think the grabby aliens model (cited in the post) provides a strong reason to doubt that there will be many so-called “quiet” aliens that hide their existence. Moreover, I think malicious grabby (or loud) aliens would not wait for messages before striking, which the Dark Forest theory relies critically on. See also section 15 in the grabby aliens paper, under the heading “SETI Implications”.
In general, I don’t think there are significant risks associated with messaging aliens (a thesis that other EAs have argued for, along these lines).
