MITRE ATT&CK

T1059.001 JavaScript T1204.001 Malicious Link T1204.002 Malicious File

The PDF file contains embedded JavaScript that leverages the CVE-2007-5659 vulnerability (Collab.collectEmailInfo). This exploit is designed to execute arbitrary code, indicated by the 'unescape()' call and the detection by ClamAV as 'Pdf.Exploit.Agent-35905'. The extracted JavaScript streams are heavily obfuscated, but the overall pattern suggests the execution of a malicious payload. The primary attack vector is likely user interaction with the malicious PDF, leading to the exploitation of the reader.

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. (identified after JavaScript deobfuscation)
ClamAV: Pdf.Exploit.Agent-35905 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-35905
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.
