The PDF contains embedded JavaScript and is flagged as malicious by ML classifiers and ClamAV (Pdf.Dropper.Agent-7329038-0). It also references external URLs, such as http://rgadmission.com/sam/img/img/index.php, which are likely used to download and execute a second-stage payload. The presence of CVE-2023-26369 related indicators suggests exploitation of a known vulnerability.

TrueType bitmap font + active content — CVE-2023-26369 related high PDF_CVE_2023_26369_RELATEDPDF embeds a TrueType font with bitmap tables (EBDT/sbix/CBDT) alongside exploit delivery indicators — CVE-2023-26369 exploits the sfac_GetSbitBitmap function in Adobe's libCoolType for arbitrary code execution. This CVE was actively exploited in the wild, but this rule does not validate the malformed EBLC/EBDT primitive.

-
PDF JavaScript exploit cluster critical PDF_JS_EXPLOIT_CLUSTERPDF combines an executable JavaScript/action surface with exploit staging indicators such as eval/unescape/fromCharCode, XFA script content, or a related CVE pattern. Benign form JavaScript remains low-severity, but this correlated cluster is high-confidence malicious behavior.
-
Embedded JS stream low PDF_JSPDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
