T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF document was flagged by multiple heuristics as malicious, including a critical finding for redirector links and a link farm. The presence of numerous embedded URLs, such as 'https://ggtraff.ru/123?utm_term=middle+school+volleyball+court+dimensions', strongly suggests an attempt to lure users to malicious sites. While no scripts were explicitly extracted, the PDF structure and link farm indicate a phishing or malware distribution attempt, likely delivered as a spearphishing attachment.

-
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.
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.

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/123?utm_term=middle+school+volleyball+court+dimensions
