T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The ML classifier strongly indicated maliciousness, and the 'SE_CALLBACK_LURE' heuristic confirms a phishing or tech-support scam pretext. Although no scripts were explicitly extracted, the presence of numerous embedded URLs suggests the document is designed to redirect the user to malicious sites, likely for credential harvesting or further malware delivery. The primary attack vector is likely spearphishing attachment, with the embedded URLs serving as the next stage.

Heuristics 4
-
Callback phishing phone lure medium SE_CALLBACK_LUREDocument asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) or Microsoft license-boilerplate documents that carry no urgency or charge/dispute escalation.
-
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 http://iavnt.com/uploads/1/3/0/5/130551132/130551132.html#westminster+confession+of+faith+larger+catechism+pdf PDF link annotation
