MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1204.001 User Execution: Malicious Link
T1059.001 PowerShell
The PDF contains a mass link farm and a critical heuristic firing for a malicious redirector link. The embedded document body text also contains the malicious URL, suggesting a lure to download or visit a malicious site. The presence of numerous Shopify links, while some are benign, is part of a common SEO poisoning tactic to distribute malicious PDFs. The primary malicious URL is https://ttraff.cc/pify?keyword=node+js+socket+io+example, which is likely used to redirect the user to a further stage of the 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.
-
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.cc/pify?keyword=node+js+socket+io+example
