MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a PDF document identified as a dropper by ClamAV. It contains embedded URLs, including one impersonating DHL, which likely leads to a malicious site. The presence of PDF_URI and EMBEDDED_URL heuristics indicates the document's intent to redirect the user to external resources. No scripts were extracted from this sample, but the overall structure suggests it's designed to deliver a second-stage payload.
