MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains an embedded URL flagged as a malicious redirector. The ML classifier also strongly indicated maliciousness. The presence of a URL within the document body, disguised with Russian text that translates to 'presentation for school', suggests a phishing or malware lure. No scripts were extracted, but the primary attack vector appears to be directing the user to the malicious URL.

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/wix?keyword=%25D0%25BF%25D1%2580%25D0%25B5%25D0%25B7%25D0%25B5%25D0%25BD%25D1%2582%25D0%25B0%25D1%2586%25D0%25B8%25D0%25B8+%25D0%25B4%25D0%25BB%25D1%258F+%25D0%25BD%25D0%25B0%25D1%2587%25D0%25B0%25D0%25BB%25D1%258C%25D0%25BD%25D0%25BE%25D0%25B9+%25D1%2588%25D0%25BA%25D0%25BE%25D0%25BB%25D1%258B+3+%25D0%25BA%25D0%25BB
