T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF file contains a link to a known malicious redirector, ttraff.me, which is likely used to distribute malware or lead users to phishing pages. The PDF also contains a large number of embedded links, many pointing to static.usrfiles.com, which is flagged as a link farm. The ML classifier also strongly indicated maliciousness. No scripts were extracted, but the presence of the malicious redirector and link farm suggests a delivery mechanism for further malicious content.

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.me/wix?keyword=template+design+for+newsletter
