T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains an embedded URL that points to a known malicious redirector. The document body, though heavily obfuscated, contains text that appears to be related to the URL's keyword, suggesting a lure. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms the malicious nature of the URL, and the 'SE_PASSWORD_ARCHIVE_LURE' heuristic suggests a common tactic to bypass security controls.

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.
-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
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=calculate+distance+between+two+points
