T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent. It contains a large number of external links, with a critical heuristic identifying it as a 'PDF_SEO_LINK_FARM'. One of the primary URLs, 'https://trafficel.ru/123?utm_term=grand+prairie+municipal+court+phone+number', is suspicious and likely leads to a phishing or malware distribution site. The document body is heavily obfuscated, but the presence of external links suggests a lure to external resources.

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://trafficel.ru/123?utm_term=grand+prairie+municipal+court+phone+number
