MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links, many of which point to other PDF files with numeric slugs, suggesting a link farm for SEO manipulation or to host malicious content. The document body contains text related to invoices and templates, aligning with the 'SE_INVOICE_LURE' heuristic. The primary heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, with 'glevaulting.com' being a dominant host. The embedded URL 'http://inwardvision.com/uploads/1/3/1/4/131452782/131452782.html#invoice+template+excel' also points to a potential lure document.
