It also modifies filenames and creates a text file/ransom note\r\n(\"HowToRestoreYourFiles.txt\"). Rook renames files by appending the \".Rook\" extension. For example, it renames\r\n\"1.jpg\" to \"1.jpg.Rook\", \"2.jpg\" to \"2.jpg.Rook\".\r\n[TLP:WHITE] win_rook_auto (20251219 | Detects win.rook.)\r\nSource: https://malpedia.caad.fkie.fraunhofer.de/details/win.rook\r\nhttps://malpedia.caad.fkie.fraunhofer.de/details/win.rook\r\nPage 1 of 1",
