MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains a large number of embedded links, many of which point to external resources hosted on platforms like Shopify and other file-sharing sites. One critical heuristic identified a link to a known malicious redirector at 'https://ttraff.ru/pify?keyword=ansys+cfd+post'. The document body, though heavily obfuscated, contains references to 'Ansys cfd post' and 'wkhtmltopdf', suggesting a lure to disguise the malicious link farm. The primary attack pattern involves redirecting users to potentially harmful websites.

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.
