T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF document contains numerous embedded links, including a redirector to 'ttraff.ru', which is flagged as malicious. The document body text, while partially corrupted, includes keywords related to 'up board model paper' and a call-to-action phrase, suggesting a lure to download potentially malicious content. The presence of a large number of external PDF links further indicates a link farm or SEO poisoning tactic, aiming to drive traffic to malicious sites.
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.ru/wb?keyword=up%20board%20model%20paper%202019%20class%2010%20pdf%20download%20sanskrit
