T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a prominent link disguised as a free calendar, which is a common lure for phishing or malware distribution. The heuristic PDF_MALICIOUS_REDIRECTOR_LINK confirms that the primary URL leads to known malicious infrastructure. The PDF_SEO_LINK_FARM heuristic indicates a large number of outbound links, many of which are likely part of a link farm designed to improve search engine ranking for malicious content. No scripts were extracted from this sample.

Heuristics 3
-
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINKPDF 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_FARMSmall 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.
-
