MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF was flagged for containing a malicious redirector link and a large number of external PDF links, suggesting a link farm. The primary malicious URL identified is https://ttraff.cc/pify?keyword=enfermedades+y+trastornos+alimentici. The document body contains garbled text but includes the same malicious URL, reinforcing its role in a redirection scheme. The presence of numerous Shopify-hosted PDF links, while some are benign, indicates a tactic to obscure the malicious destination.

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.
