T1566.001 Spearphishing Attachment
The PDF was flagged by ML classifiers and ClamAV as malicious, indicating a phishing or trojan payload. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests the document's purpose is to trick the user into decrypting a malicious archive. No scripts were extracted, but the presence of embedded URLs and the overall detection suggest a phishing attempt, likely delivered as a spearphishing attachment.

Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning

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/~3/1LSSs5qy-i4/square?utm_term=terraria+connecting+to
