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

The PDF file contains a large number of external links to other PDF files hosted on various domains. This behavior is indicative of a link farm, often used for SEO manipulation or to distribute malicious content. The document body contains text related to 'Hava nagila sheet music pdf', which appears to be a lure to disguise the malicious nature of the links. No scripts were extracted from this sample.

  • Embedded URL info EMBEDDED_URL
    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.
