T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a large number of external links, many with SEO-like slugs related to popular games and free currency. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of such links, suggesting a link farm or scam operation. The presence of a 'download button' heuristic further supports the lure of clicking these links for a perceived benefit. No scripts were extracted, but the primary attack vector appears to be directing users to malicious or scam websites via embedded links.
