MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file was identified as malicious due to a critical heuristic firing for PDF_MALICIOUS_REDIRECTOR_LINK, indicating it contains links to known malicious redirector infrastructure. Additionally, the PDF_SEO_LINK_FARM heuristic fired, revealing a large number of embedded external links, many hosted on cdn.shopify.com. The primary malicious URL identified is https://ttraff.cc/pify?keyword=description+vocabulary+pdf. The document body contains garbled text but includes the aforementioned malicious URL and several other PDF links, reinforcing the attack pattern.
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.
-
