T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a high number of external links, many pointing to Weebly-hosted PDFs, indicating a link farm. The ML classifier strongly flagged this PDF as malicious. While no scripts were explicitly extracted, the PDF_URI and PDF_SEO_LINK_FARM heuristics suggest the document's primary purpose is to redirect users to a network of other documents, potentially for malicious purposes such as phishing or malware distribution.

Heuristics 4
-
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.
-
External URI info PDF_URIPDF contains an external URL action
-
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://trafficel.ru/aws?utm_term=count+worksheets+in+a+workbook+vba PDF link annotation
