Malware Insights
This PDF file was flagged by multiple heuristics as malicious, including a critical ClamAV detection for Pdf.Dropper.Agent-9275980-0 and an ML classifier output of 0.999976. The PDF contains a large number of external links, many hosted on similar domains with numeric or generic slugs, indicating a link farm or SEO poisoning tactic. One of the embedded URLs is http://friendswoodflutist.com/uploads/1/3/1/4/131438819/131438819.html#custom+resolution+utility+guide, which appears to be the lure text. The primary function seems to be redirecting users to potentially malicious content hosted on these external sites.

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.
