T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged by multiple heuristics, including a machine learning classifier and ClamAV, indicating malicious intent. It contains embedded URIs, with the primary one being `https://trafftec.ru/123?utm_term=construct+binary+tree+from+preorder+and+inorder+traversal+lintcode`, which likely leads to a phishing or malware distribution site. The presence of embedded URIs suggests an attempt to redirect the user to external content, consistent with phishing or credential harvesting.

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://trafftec.ru/123?utm_term=construct+binary+tree+from+preorder+and+inorder+traversal+lintcode PDF link annotation
