MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document was generated by wkhtmltopdf and contains a significant number of embedded external links. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external PDF links, suggesting a link farm or redirection scheme. The primary purpose appears to be to lure users to click on these links, which lead to other PDFs or HTML files hosted on various domains, likely for phishing or malware distribution.
