MITRE ATT&CK

T1203 Exploitation for Client Execution T1059.001 PowerShell

The sample is a PDF file that exploits the Adobe Reader CoolType SING font vulnerability (CVE-2010-2883). This vulnerability allows for arbitrary code execution. Embedded JavaScript streams were also detected, suggesting further malicious activity. The URL for 'datanumen.com' was found within the document, which may be related to the exploit or a secondary payload delivery.

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.
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
