MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains multiple critical heuristic firings indicating the exploitation of CVE-2009-4324, CVE-2009-0927, and CVE-2007-5659. These exploits target the PDF viewer's JavaScript engine to execute malicious code. The presence of deobfuscated JavaScript files suggests the sample attempts to download and execute a second-stage payload, although the specific URLs or actions are not directly extractable from the provided evidence.

Heuristics 6

media.newPlayer — CVE-2009-4324 critical CVE exact CVE_2009_4324

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. (identified after JavaScript deobfuscation)
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. (identified after JavaScript deobfuscation)
