T1566.002 Spearphishing Attachment
T1059.001 PowerShell
T1204.002 Malicious Link
The PDF file contains a large number of embedded links, with a significant portion pointing to a known malicious redirector. The document body text, though partially corrupted, suggests a lure related to a "factoring worksheet". The primary malicious URL identified is https://ttraff.cc/pify?keyword=factoring+worksheet+a+1, which is likely used to redirect the user to a malicious site for further exploitation or credential harvesting. The presence of a link farm and a malicious redirector indicates a social engineering attack aimed at driving traffic to malicious infrastructure.

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=factoring+worksheet+a+1
