概要

A spam email appearing to be a WhatsApp notification with the subject of "A sound memo" and pretending to come from WhatsApp <peter.kroell@towncountry.at> ( random email addresses ). The email contains a zip file attachment that attempts to download various Trojans and password stealers especially banking credential stealers, which may include cridex, dridex, dyreza and various Zbots, cryptolocker, ransomware and loads of other malware on your computer. The attackers use email addresses and subject lines that will entice a user to read the email and open the attachment. A very high proportion are being targeted at small and medium size businesses, with the hope of getting a better response than they do from consumers.
