MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, many of which point to other PDF files hosted on various domains. This behavior is indicative of a link farm or a distribution network for malicious content. The document body, though heavily obfuscated, contains references to 'sales funnel book pdf' and the authoring application 'wkhtmltopdf', suggesting a lure to entice users to click on the embedded links. No scripts were extracted from this sample.

Heuristics 3
