T1204.002 Malicious File: User Execution: Malicious Link T1059.001 Command and Scripting Interpreter: PowerShell T1059.003 Command and Scripting Interpreter: Windows Command Shell T1566.001 Phishing: Spearphishing Attachment

The PDF file contains embedded JavaScript and triggers a critical heuristic for the CVE-2010-2883 Adobe Reader CoolType SING font exploit. The presence of JavaScript streams and the specific exploit indicate the document is designed to compromise the user's system upon opening. The embedded JavaScript is likely responsible for downloading and executing a secondary payload, although the exact functionality is obscured.

Heuristics 6

Adobe Reader CoolType SING font exploit — CVE-2010-2883 critical CVE likely CVE_2010_2883

PDF embeds a TrueType/OpenType font with an actual SING table and pairs it with JavaScript heap-spray shellcode. This matches the public Adobe Reader CoolType SING exploit shape for CVE-2010-2883.
ASCIIHexDecode filter (with exploit indicators) medium PDF_FILTER_HEX

Hex-encoding filter present alongside exploit delivery indicators — often used to hide payload or shellcode bytes
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.
XFA form low PDF_XFA

PDF uses XML Forms Architecture — can contain script logic
