MITRE ATT&CK

T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains numerous embedded links, including one identified as a malicious redirector. The primary lure appears to be related to 'deformidades de los pies pdf', suggesting a phishing attempt to trick users into visiting a malicious site. The document's structure and content indicate it's designed to host a large number of SEO-optimized links, likely for traffic redirection or further malicious activity.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
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.
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
