Teslacrypt Spam Campaign: “Unpaid Issue…”

概要

Cyber criminals continue to use exploit kits to infect victims with ransomware but they also use MALSPAM emails to lure possible victims – a key vector into an enterprise environment that lacks the proper security controls, and one with insufficient information security training for end users. Some examples are email messages claiming to be in regards to an overdue bill or invoice, utilizing such terminology in the subject line and given file name, such as invoice.zip or payment_doc_298427.zip
