Cybercrime, new MassLogger campaign on false invoices

Technical analysis by the Malware Hunter JAMESWT

New cybercrime campaign to convey MassLogger. The bait is always false invoices. The .doc file contacts a link from which the malware is downloaded

MassLogger still attacks with the usual fake invoice bait coming from a real company. The attachment contains a .doc file which, if opened, contacts a link from which the malware is downloaded. This is a keylogger that steals login credentials and sensitive data, which are transmitted to C2 servers via smtp.
