MITRE ATT&CK

T1059.001 JavaScript/Shell Script: JavaScript Execution T1204.001 Malicious Link: Malicious Link T1204.002 Malicious File: Malicious File

The PDF file contains embedded JavaScript triggered by an OpenAction, indicating an attempt to exploit vulnerabilities. Specifically, the presence of 'Collab.collectEmailInfo' and 'util.printf' firings strongly suggest exploitation of CVE-2007-5659 and CVE-2008-2992, respectively. These vulnerabilities allow for arbitrary code execution, likely to download and run a secondary payload. The extracted JavaScript artifact, 'javascript_obj0013_001.js', further supports the presence of malicious scripting.

Heuristics 7

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)
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.
