MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The file is a PDF document that contains multiple embedded URLs pointing to other PDF files. The document body text attempts to disguise itself as a 'Collage maker free for pc' tool, likely to trick users into downloading and opening the linked malicious PDFs. The ClamAV heuristic 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports the phishing and malware delivery intent.
