This rule detects HTTP traffic where the referer header contains domains commonly associated with advertising networks (doubleclick.net, adnxs.com, googlesyndication) and the URI contains file extensions typically used for executable or script files (exe, ps1, msi, hta, vbs). This combination suggests a malvertising redirect attempt leading to the download of malicious files.
