MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of embedded links to external PDF documents hosted on various domains. This behavior is indicative of a link farm, often used for SEO manipulation or to distribute malicious content. The ClamAV detection and ML classifier strongly suggest malicious intent, likely phishing or malware distribution through these linked PDFs.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
