MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF document was flagged as malicious due to its inclusion of a link farm containing numerous external PDF links. One of these links, 'https://ttraff.cc/pify?keyword=la+boite+a+merveille+pdf+%25D8%25A8%25D8%25A7%25D9%2584%25D8%25B9%25D8%25B1%25D8%25A8%25D9%258A%25D8%25A9', points to known malicious redirector infrastructure. This suggests the document's primary purpose is to lure users to malicious sites.

Heuristics 3

PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF 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_FARM

Small 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_URL

One 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.
