T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains a lure related to 'whatsapp app 2019 new version apk' and embeds numerous links. One of these links, 'https://ttraff.com/pify?keyword=whatsapp+app++2019+new+version+apk', points to known malicious redirector infrastructure. The document's structure and embedded links suggest it is part of a phishing or scam campaign designed to redirect users to malicious sites. No scripts were extracted, but the PDF's nature as a link farm points to a social engineering attack.

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.
-
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://ttraff.com/pify?keyword=whatsapp+app++2019+new+version+apk
