T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF document flagged by multiple heuristics as malicious, including a critical finding for linking to known malicious redirector infrastructure. The ML classifier also strongly indicated maliciousness. The embedded URL points to a suspicious domain, likely serving as a lure or a distribution point for further malicious activity. No scripts were extracted, but the PDF structure and malicious URL indicate 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://traffine.ru/aws?utm_term=agrobacterium+transformation+freeze+thaw+method In PDF document text
