MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious File

The PDF file contains embedded JavaScript and is configured with an OpenAction to trigger its execution upon opening. A critical heuristic firing indicates the use of CVE-2007-5659 (Collab.collectEmailInfo), a known vulnerability for arbitrary JavaScript execution in older Adobe Reader versions. The embedded JavaScript stream, named 'javascript_obj0013_001.js', is likely responsible for exploiting this vulnerability and downloading a secondary payload. The presence of JavaScript actions and unescape calls further supports this attack vector.

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.
