T1566.002 Phishing: Spearphishing Attachment
T1059.001 Command and Scripting Interpreter: PowerShell
The PDF file was flagged by multiple critical heuristics for containing a malicious redirector link and a large number of external PDF links, suggesting a link farm or SEO manipulation tactic. The ML classifier also strongly indicated maliciousness. The primary malicious URL identified is 'https://ttraff.ru/pify?keyword=anacardium+excelsum+pdf', which is likely used for redirection. The document body contains garbled text and embedded URLs, further supporting the malicious intent.

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.
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL https://ttraff.ru/pify?keyword=anacardium+excelsum+pdf
