T1566.001 Spearphishing Attachment
The sample is a PDF file flagged by ClamAV as Pdf.Phishing.Trojan. The ML classifier also indicated a high probability of maliciousness. While no scripts were extracted, the presence of an embedded URI pointing to a Google feedproxy URL suggests an attempt to redirect the user to a malicious site. The document body is heavily obfuscated, preventing analysis of its specific content, but the overall indicators point to a phishing or malware distribution attempt.

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://feedproxy.google.com/~r/sq/ugae/~3/CHqDoFjlE84/square?utm_term=american+heart+association+bls+test+answers+2016
