MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains numerous links to external websites, many of which are identified as malicious redirectors or part of a link farm. The primary link, disguised as an RPG guide, leads to a known malicious redirector. This suggests the document is designed to phish users or lead them to malware distribution sites.

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
