T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a link to known malicious redirector infrastructure, identified by the 'PDF_MALICIOUS_REDIRECTOR_LINK' heuristic. The ML classifier also flagged this PDF as malicious with high confidence. The presence of a password-protected archive lure suggests an attempt to bypass gateway security, and the embedded URL is likely part of a multi-stage attack. No scripts were extracted, but the document body and heuristics point to a redirection-based attack pattern.

Heuristics 4
-
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.
-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
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://ggtraff.ru/strik?keyword=bylaws+example+pdf In PDF document text
