T1566.001 Spearphishing Attachment T1059.007 JavaScript

This PDF document contains multiple links to compromised WordPress sites, likely serving as a distribution point for malware. The ClamAV detection and the presence of numerous suspicious URLs indicate a phishing or malware distribution attempt. Although no scripts were explicitly extracted, the PDF structure and embedded links suggest it's designed to redirect users to malicious content.

  • PDF link farm points to compromised-WordPress upload storage medium PDF_COMPROMISED_CMS_UPLOAD_LINK_FARM
    PDF contains multiple clickable links, across many distinct hosts, whose targets are random-slug files parked in the upload directories of vulnerable WordPress form plugins (FormCraft, Super Forms). This is the hallmark of the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains hosted on compromised sites. The PDF itself carries no exploit — the risk is the linked destinations.

  • Embedded URL info EMBEDDED_URL
