T1059.007 JavaScript T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The PDF file contains obfuscated JavaScript, flagged by multiple heuristics and a machine learning classifier as malicious. The embedded JavaScript attempts to decode and execute a second-stage payload, as indicated by the presence of 'eval' and string manipulation functions. The ClamAV detection name 'Pdf.Exploit.Agent-36142' further supports the malicious nature of this file.

Heuristics 4

Hex-obfuscated scripting name object critical PDF_OBFUSCATED_NAME_OBJECT

A PDF name object that drives script execution (/JavaScript or /JS) is written with #XX hex escapes to hide it from string-based scanners — e.g. /J#61v#61S#63r#69p#74 decoding to /JavaScript. Legitimate PDF producers always write these names literally; hex-encoding an executable name is a deliberate evasion used by exploit-kit and dropper PDFs.
