BazarLoader phishing lures: plan a Halloween party, get a bonus and be fired in the same afternoon, (Thu, Oct 22nd)

Phishing messages distributing BazarLoader have come to be commonplace in the past six months, but in the last couple of weeks I’ve been seeing more and more e-mails spreading this malware caught in my quarantine.
