The attempts to infect systems via malicous javascript in e-mail are quite high at the moment, all trying to fake some urgency to make me open it without checking. Some recent samples:

Or this attempt at creating urgency:

And some mix of a standard message in some system with a company disclaimer:

Which looks like somewhat readable javascript but is quite obfuscated when I try to find out what it does:
RXPBqXKexc = "    if ( result == null ) {      return operator === \"!=\";     }     if ( !operator ) {      return true;     ";
mowSJrO.splice(7, italianoI + 2);
errol = mowSJrO[3 * 5 - 3 * 3].split("princeton").join("");
var SsDEwXL = this[errol];
cvVwbXTvf = "UjAVgFt";

Update: No real surprise: it is all Locky ransomware being spammed, according to Massive Volume of Ransomware Downloaders being Spammed - trustwave and other sources.
