T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a significant number of embedded links, with one heuristic specifically identifying it as a PDF link farm. One of the embedded URLs, 'https://ttraff.ru/pify?keyword=information+sur+le+biodome+de+montreal', is flagged as a known malicious redirector. The ML classifier also strongly indicated maliciousness. The document body itself is heavily obfuscated and contains a mix of metadata and what appears to be a reconstructed URL, suggesting an attempt to disguise 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=information+sur+le+biodome+de+montreal
