T1204.002 Malicious Link
T1059.001 PowerShell
The PDF contains a large number of embedded links, many pointing to Shopify domains, suggesting a link farm or SEO manipulation tactic. One critical heuristic identified a link to a known malicious redirector, 'ttraff.cc', which is likely the primary malicious payload delivery mechanism. The document body, though partially corrupted, contains the text 'how to draw bending moment diagram pdf' and a URL that reconstructs to 'https://ttraff.cc/pify?keyword=how+to+draw+bending+moment+diagram+pdf', indicating a lure to disguise the malicious link. No scripts were extracted from this sample.
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.cc/pify?keyword=how+to+draw+bending+moment+diagram+pdf
