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

The PDF contains a large number of embedded URLs, forming a link farm, and a heuristic firing for 'SE_DOWNLOAD_BUTTON' indicates a lure for the user to click. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' strongly suggests a phishing or malicious download campaign. The document body text, though partially corrupted, mentions 'Malayala manorama 2019 calendar pdf download', likely a pretext for the malicious links.

Heuristics 4
