MITRE ATT&CK

T1059.001 JavaScript/JScript T1204.001 User Execution: Malicious Link T1204.002 User Execution: Malicious File

This PDF file contains embedded JavaScript and triggers an OpenAction, indicating malicious intent. Critical heuristics identify multiple Adobe Reader exploits (CVE-2009-0927, CVE-2007-5659, CVE-2008-2992), suggesting the file is designed to leverage these vulnerabilities. The embedded JavaScript, although obfuscated, is likely responsible for executing the exploit payload.

Heuristics 9

Collab.getIcon — CVE-2009-0927 critical CVE exact CVE_2009_0927

PDF JavaScript calls Collab.getIcon — CVE-2009-0927 is a stack buffer overflow in Adobe Reader triggered by Collab.getIcon() with a crafted argument. Allows arbitrary code execution. (matched in decompressed stream)
Collab.collectEmailInfo — CVE-2007-5659 critical CVE exact CVE_2007_5659

PDF JavaScript calls Collab.collectEmailInfo — CVE-2007-5659 is a buffer overflow in Adobe Reader triggered by a long argument or heap-sprayed message field passed to Collab.collectEmailInfo(). Part of a series of Acrobat JS API exploits. (matched in decompressed stream)
util.printf — CVE-2008-2992 critical CVE exact CVE_2008_2992

PDF JavaScript calls util.printf() — CVE-2008-2992 is a stack buffer overflow in Adobe Reader triggered by a long format-specifier argument. Widely exploited in the wild after disclosure. (matched in decompressed stream)
ClamAV: Pdf.Exploit.CVE_2009_0927-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.CVE_2009_0927-1
OpenAction trigger high PDF_OPENACTION

PDF has an /OpenAction — code runs automatically when opened
unescape() call high PDF_UNESCAPE

unescape() found — often used to decode shellcode in PDF JS exploits (matched inside decoded stream)
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.
