T1059.001 PowerShell
The PDF file was flagged as malicious by an ML classifier and contains a link to a known malicious redirector. The embedded URL points to 'https://ttraff.ru/wb?keyword=always%20with%20me%20ukulele%20pdf', which is classified as a malicious redirector. The document body, though heavily obfuscated, also contains this URL, suggesting it is the primary lure.

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.
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.
-
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/wb?keyword=always%20with%20me%20ukulele%20pdf
