MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious Link: Malicious File

The file is identified as a PDF dropper by ClamAV. It contains embedded URLs that are likely used to trick users into downloading further malicious content, disguised as a book titled 'the cloud collector a thriller'. The presence of a visual download button heuristic further supports this lure-based attack pattern. The primary malicious URLs identified are http://uncpbisdegree.com/download3.php?q=the-cloud-collector-a-thriller.pdf and http://uncpbisdegree.com/download4.php?q=the-cloud-collector-a-thriller.pdf.
