Disinformation is now a cyber weapon and a major security risk. It is a menacing attack made through the information spaces that we all spend so much time in every day. The entire information ecosystem is vulnerable, which means so are societies, democratic processes, highly visible brands, and people in general. Disinformation is not fake news. It is a weapon that creates confusion and misunderstanding by publicizing questionable material. Even if the disinformation is refuted—it is enough that it has been seen or heard.
