According to dozens of pages of documents, and seven people directly involved in the effort, the firms that Weinstein hired included Kroll, which is one of the world’s largest corporate-intelligence companies, and Black Cube, an enterprise run largely by former officers of Mossad and other Israeli intelligence agencies. Black Cube, which has branches in Tel Aviv, London, and Paris, offers its clients the skills of operatives “highly experienced and trained in Israel’s elite military and governmental intelligence units,” according to its literature.

Two private investigators from Black Cube, using false identities, met with the actress Rose McGowan, who eventually publicly accused Weinstein of rape, to extract information from her.
