MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a large number of embedded links to other PDF files, masquerading as a "Baby shower invitation online template free". This heuristic, combined with ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0', strongly suggests a phishing or malware distribution campaign. The embedded links likely serve to redirect users to malicious content or further stages of an attack.
