MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

This PDF file contains multiple critical exploit firings, including CVE_2009_0927, CVE_2007_5659, and CVE_2008_2992, indicating it is designed to exploit vulnerabilities in PDF readers. The presence of embedded JavaScript, triggered by an OpenAction, and the detection of a suspicious JavaScript file (javascript_obj0007_000.js) strongly suggest that the document's primary purpose is to download and execute a secondary payload. The specific exploits targeted are well-known and commonly used for initial compromise.

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)
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
