MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

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 or a distribution mechanism for further malicious content, as suggested by the 'PDF_SEO_LINK_FARM' heuristic and ClamAV detection. The ML classifier also strongly indicated maliciousness. No scripts were extracted from this sample.
