T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF contains a lure for a download, and a critical heuristic firing indicates it links to known malicious redirector infrastructure. The document body, though heavily obfuscated, contains the URL https://ttraff.cc/pify?keyword=cards+against+humanity+pdf+download, which is likely the initial stage of a malicious download chain. The PDF also contains a large number of links to other PDFs, suggesting a link farm SEO tactic.
Heuristics 4
-
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.
-
Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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.cc/pify?keyword=cards+against+humanity+pdf+download
