MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains a large number of external links to other PDF files, masquerading as a service for downloading e-aadhaar cards. This technique is commonly used for SEO poisoning and phishing attacks, aiming to redirect users to malicious sites or download malware. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports its malicious nature.
