T1566.001 Spearphishing Attachment
The PDF file contains a critical heuristic firing indicating it links to known malicious redirector infrastructure. The embedded URL, https://cctraff.ru/strik?keyword=haier+esa405r+5000+btu+room+air+conditioner+manual, is the primary indicator of malicious intent. This suggests the document is designed to lure users to a compromised site, likely for further exploitation or credential harvesting.

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://cctraff.ru/strik?keyword=haier+esa405r+5000+btu+room+air+conditioner+manual In PDF document text
