T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The file is identified as malicious by ClamAV with a signature indicating a phishing trojan. The presence of a visual download button and an embedded URI suggests a phishing attempt designed to trick users into downloading a payload. While the specific embedded URL was found to be benign, the overall context points to a malicious workflow.

Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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/r_nBws6J8g8/square?utm_term=total+sms+storage+android+apk+download PDF link annotation
