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

The PDF file contains a link farm with multiple external PDF URLs, disguised as an 'Axis bank balance sheet pdf'. This heuristic indicates a phishing or malware distribution attempt. The ClamAV detection confirms its malicious nature, classifying it as Pdf.Phishing.TtraffRobotInstall. The numerous embedded URLs suggest the primary goal is to redirect users to download further malicious content.

    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
