MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains a large number of external links, many of which point to PDF files hosted on various domains. The document body mentions 'Raiders of the north sea android review', suggesting a lure to a potentially malicious website. The primary heuristic indicates the presence of a PDF link farm, designed to artificially inflate search engine rankings or distribute malicious content. The embedded URL points to a specific HTML file that also appears to be part of this link farm.
