One of threat actors’ favorite malware delivery schemes is social engineering as it remains highly effective against a variety of targets. Malicious spam, in particular, is one of the biggest threats enterprises are facing today in the form of daily deliveries of fake invoices, contract, and other receipts.
Those attachments can be scripts, PDFs, or Microsoft Office documents, the latter often containing macros designed to retrieve a malicious payload as soon as users activate them.
