MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link

This PDF file contains embedded JavaScript that utilizes a character-table decoding stager to exploit multiple Adobe Reader vulnerabilities, including CVE-2009-4324, CVE-2009-0927, CVE-2007-5659, and CVE-2008-2992. The script is designed to execute arbitrary code, likely to download and run a second-stage payload. The specific vulnerabilities targeted indicate a focus on older, unpatched Adobe Reader versions.

ClamAV: Pdf.Exploit.Dropped-91 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Dropped-91
Large character-table JavaScript eval stager high PDF_JS_LARGE_CHAR_TABLE_EVAL_STAGER

PDF JavaScript contains a large numeric index array, a short character table, an indirect eval sink, and a long loop that reconstructs a hidden stage. This is an exploit-kit staging technique even when the recovered first stage is still encoded.
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.
