MITRE ATT&CK
T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains a link farm and a critical heuristic firing for a malicious redirector. The primary malicious URL is https://ttraff.cc/pify?keyword=hallelujah+guitar+chords+pdf, which is likely used to redirect the user to a malicious site. The document body contains garbled text but includes the same malicious URL, suggesting an attempt to disguise the malicious intent with a seemingly innocent topic. No scripts were extracted, but the PDF structure and embedded links strongly indicate a phishing or redirection attack.

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=hallelujah+guitar+chords+pdf
