T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
T1059.001 PowerShell
The PDF file contains multiple embedded links, with a critical heuristic identifying a malicious redirector. The document body text and heuristics suggest a lure impersonating a document signing service, encouraging the user to click a 'download' link. This link, 'https://ttraff.ru/pify?keyword=managed+services+agreement+template', is identified as a malicious redirector. The presence of numerous links to external PDFs, including one hosted on cdn.shopify.com, indicates a link farm strategy, likely to obscure the final malicious destination.
Heuristics 5
-
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.
-
Document signing service impersonation lure medium SE_DOCUSIGN_LUREDocument impersonates DocuSign, Adobe Sign, or a similar signing service in a signing-request context
-
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/pify?keyword=managed+services+agreement+template
