T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
This PDF document is classified as malicious due to its inclusion of a large number of external links, a common tactic in SEO spam and phishing campaigns. The document body, though partially obfuscated, contains text related to 'Asp.net core 3.0 web api tutorial for beginners', which appears to be a lure to disguise the malicious intent. The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' strongly indicates that the document is designed to trick users into believing they are involved in a lottery or parcel delivery scam, requiring them to interact with the embedded links.

Heuristics 5
-
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.
-
Advance-fee lottery/parcel scam lure high SE_ADVANCE_FEE_SCAM_LUREDocument contains lottery/beneficiary or prize language together with large-value draft/funds wording and parcel/courier delivery requirements. This is a classic advance-fee fraud document shape.
-
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://bluestonewinery.com/uploads/1/3/1/3/131384771/131384771.html#asp.net+core+3.0+web+api+tutorial+for+beginners
