T1566.002 Spearphishing Attachment
T1059.001 PowerShell
The PDF contains embedded JavaScript and a mass of external links, with one specific link identified as a potential lure. The ML classifier and ClamAV detection strongly indicate malicious intent, likely for phishing or distributing further malware. The PDF_SEO_LINK_FARM heuristic suggests a tactic to generate traffic or disguise malicious content through numerous links.

Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
-
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 https://lazav.co.za/YmrXLWy8?keyword=cdl%20pre-trip%20inspection%20study%20guide%20class%20a%20and%20class%20b%20cdl%20prosecutor%20nc
