A researcher for Microsoft-owned (MSFT.O) LinkedIn said Black Cube, based in Israel, created a network of fake personas that used bogus job postings to connect with their targets on the platform. Black Cube did not immediately respond to messages seeking comment. The operation attributed to Black Cube by LinkedIn began in 2020 and targeted at least 12 activists and journalists who have been critical of Hungarian Prime Minister Viktor Orban.
