Re: Filtering compressed (zip,rar) attachments containing executable (exe,etc) files.

@scott

Hi,

The problem is that I have a lot of valid .zip/.rar files passing through the system. I'd like to only intercept compressed files that contain executables. My biggest problem at the moment are compressed .exe and .js files !

Filtering compressed (zip,rar) attachments containing executable (exe,etc) files.

Mailenable does a great job at filtering attachments that are executables.

But we are seeing a lot of executables getting through in zip/rar files.

Is there any way to filter them too ?

It's a serious problem (CryptoLocker, etc.) !!!

Thanks. Stuart
