MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a mass of external links, many of which point to suspicious domains or are part of a link farm designed to manipulate search engine results. One prominent link, 'https://ttraff.cc/pify?keyword=tutorialspoint+advanced+excel+functions+pdf', is identified as a malicious redirector. The document body, though heavily obfuscated, contains references to PDF and wkhtmltopdf, suggesting it's a crafted document intended to host these links. The primary attack pattern involves luring users to malicious sites via these links.

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.
