MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a large number of embedded links pointing to external PDF files hosted on various domains. This behavior is indicative of a link farm or a distribution mechanism for further malicious content, as suggested by the ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0'. The document body text, though partially corrupted, mentions converting scanned PDFs to editable Word documents, which could be a lure. No scripts were extracted from this sample.
