T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF file contains a significant number of embedded links, many of which point to external PDF files hosted on various domains. One URL, 'https://ttraff.cc/wb?keyword=basic%20life%20support%20(bls)', is flagged as a malicious redirector. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, suggesting a tactic to manipulate search engine results or distribute malicious content. The document body is unreadable, but the heuristics and numerous URLs strongly suggest a link-farming or redirection attack.
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.
-
External URI info PDF_URIPDF contains an external URL action
-
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/wb?keyword=basic%20life%20support%20\(bls\)%20provider%20manual%2015-1010%20pdf
