MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF contains numerous embedded links, with a critical heuristic firing for a malicious redirector pointing to 'ttraff.ru'. Another critical heuristic identified a PDF link farm, suggesting SEO poisoning tactics. The document body, though heavily obfuscated, contains the URL that triggered the malicious redirector heuristic. The primary attack pattern involves luring users through a seemingly relevant document to a malicious site.

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=carcinoma+de+pequenas+c%25C3%25A9lulas+de+pulm%25C3%25A3o+pdf
