T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF was flagged by multiple heuristics, including a critical finding for a malicious redirector link and a ClamAV detection. The ML classifier also strongly indicated maliciousness. The primary IOC is the malicious URL embedded within the document, which is likely used to lure victims to a compromised site. No scripts were extracted, but the PDF structure and redirector link strongly suggest a phishing or malware delivery attempt.

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://traffmen.ru/123?utm_term=compound+areas+worksheet In PDF document text
