T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The sample was flagged by a machine learning classifier and ClamAV as malicious, with a high risk score. It contains embedded URIs, one of which points to a Google feed proxy, and numerous other unknown URLs that are likely part of a phishing or malware distribution campaign. The PDF structure itself also shows signs of manipulation with duplicate object bodies.

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 http://oaklandchildcare.org/sites/default/files/webform/85278691340.pdf In PDF document text
