[QUOTE="Andy Ful, post: 803554, member: 32260"] [USER=53544]RoboMan[/USER] Those rules are not default-deny. They are similar in idea to Attack Surface Reduction for scripts and MS Office.(y) These are pretty good HIPS rules, which can stop most malicious scripts and macros. But, I am afraid that they cannot stop some well known infections chains. For example, they can be bypassed by: [LIST] [*]files with some well known dangerous extensions: BAT, CMD, CPL, CHM, etc. [*]a shortcut or macro which uses some LOLBins like cmd.exe, wmic.exe. [/LIST] There can possibly be a problem with macros and scripts, which uses WMI, because when script Interpreter uses WMI to run something, then the child process is not the child of the Interpreter. This can usually fool many security solutions (but not WD Exploit Protection). [/QUOTE]
