T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains embedded text and a URL that is flagged as malicious, suggesting a phishing attempt. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' specifically identifies the URL 'https://ttraff.cc/pify?keyword=booking+holdings+annual+report' as a redirector to malicious infrastructure. The 'SE_INVOICE_LURE' heuristic further supports the phishing pretext by indicating the document uses an invoice or payment-related lure.

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.
-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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.cc/pify?keyword=booking+holdings+annual+report
