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

The PDF contains a large number of external links to other PDF files hosted on various domains, indicating a link farm or redirection strategy. ClamAV identified this as 'Pdf.Phishing.TtraffRobotInstall-7605656-0', and a machine learning model assigned a high probability of maliciousness. The document body contains garbled text and references to 'Ayatul kursi with urdu translation mp3 free download hamariweb', which appears to be a lure to disguise the malicious link distribution.
