Heuristics 5

Adobe Flash Player RichMedia exploit critical CVE likely CVE_2011_0611_FLASH_RICHMEDIA

PDF combines RichMedia Flash activation with an embedded AS3 SWF loader (ByteArray/loadBytes) and shellcode heap-spray staging. This is the static exploit shape associated with CVE-2011-0611 Flash content delivered through Adobe Reader.
RichMedia (Flash) high PDF_RICHMEDIA

PDF contains /RichMedia (Adobe Flash) which is a historic exploit vector
Embedded file low PDF_EMBEDDED

PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
PDF paints image(s) but contains no text operators info PDF_IMAGE_ONLY_LURE

PDF has 1 image XObject(s) and the content stream contains no text-emitting operators (BT/ET, Tj, TJ, ', ") in either raw bytes or decompressed streams — this is the screenshot-as-PDF pattern used to bypass text-based scanners and to deliver instructions purely through rendered pixels. It is informational unless paired with invisible links or risky URI context.
