MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF contains embedded Flash content and JavaScript actions, indicating an attempt to exploit a vulnerability. The embedded SWF file and JavaScript stream are common delivery mechanisms for exploits. While the embedded URL was confirmed benign, the presence of these exploit vectors warrants a high degree of suspicion.

Heuristics 5

RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
JavaScript action low PDF_JAVASCRIPT

PDF contains a /JavaScript action. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded JS stream low PDF_JS

PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
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.
