MITRE ATT&CK

T1059.001 JavaScript T1204.001 Malicious Link or Trusted URL T1204.002 Malicious File

The PDF file contains embedded JavaScript and triggers an OpenAction, indicating an attempt to execute malicious code upon opening. Critical heuristics identify specific CVEs (CVE_2009_0927, CVE_2007_5659, CVE_2008_2992) related to PDF vulnerabilities, and ClamAV detections confirm it as a malicious PDF exploiting these flaws. The embedded JavaScript stream, identified as 'javascript_obj0013_001.js', likely contains shellcode, as suggested by the 'Js.Exploit.Shellcode-18' ClamAV detection on extracted artifacts.

Heuristics 10

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.
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.
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.
ClamAV: Pdf.Exploit.CVE_2009_0927-1 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.CVE_2009_0927-1
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV

ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
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
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.
Suspicious extracted artifact info 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.

Extracted artifacts 1

Files carved from inside the sample during analysis.
