The PDF document contains embedded Adobe Flash content that exploits CVE-2010-1297, a vulnerability in Flash Player.

Heuristics 6

  • Adobe Flash authplay SWF exploit in PDF — CVE-2010-1297 critical CVE likely CVE_2010_1297_FLASH_RICHMEDIA
    PDF combines RichMedia Flash activation, a crafted SWF with ActionScript prototype/AVM-era markers or the AES-PHP/authplay variant markers, and PDF-side shellcode heap-spray staging. This is the static delivery shape associated with CVE-2010-1297 in Adobe Reader's bundled authplay.dll.
  • 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.
