I'm wondering, why Sandstorm does not recognize and block Locky.
Yesterday a E-Mail passed the UTM, with attached payment_document_659857.zip, containing *.js scripts.
The ZIP was not encrypted and for my unterstanding Sandstorm should have analyzed this file and blocked it, as the *.js are very suspicious, as the arey downloading the Locky payload.
On our Exchange Server, the E-Mail was detected by Trendmicro Scanmail for Exchange as JS_LOCKY.KF
