MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link

The PDF file contains embedded JavaScript and is configured with an OpenAction to trigger its execution upon opening. The critical CVE-2007-5659 heuristic firing indicates the use of the Collab.collectEmailInfo method, a known vector for exploiting this vulnerability. The embedded JavaScript, identified as 'javascript_obj0013_001.js', is likely responsible for downloading and executing a secondary payload, although its exact function is obfuscated. The presence of JavaScript actions and the specific exploit technique strongly suggest a malicious intent to compromise the user's system.

Heuristics 6

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)
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.
