Despite the link appearing to be from "royalmail.com" it's actually a Google redirector..


This bounces to centregold.org [ - Krek Ltd, Russia] then a load balancer at rns.tobeylabs.com/tracking/delivery/tracking.php?id=554 [ - KingServers, Netherlands] then either http://booniff.com/delivery/Pack_9356667UK.zip [ - Amino Communications, US] or https://purolator.topatlantanursinghomelawyer.com/tracking/parcel/Notification_37352742UK.zip [ - KingServers, Netherlands].

Note that the name of the .ZIP is generated dynamically, so there is some variation in filenames.

Inside the ZIP files is a malicious script (e.g. Pack_9356667UK.js) which according to Hybrid Analysis then communicates with a website at [the same KingServers /24 as before!] and it drops a file mstsc.exe with VirusTotal detection rate of 11/57.
