T1566.001 Spearphishing Attachment T1059.001 PowerShell

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 document body itself is heavily obfuscated and does not provide clear textual lures, but the sheer volume of outbound links points towards a malicious intent, likely related to phishing or malware distribution.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
