MITRE ATT&CK

T1059.001 PowerShell T1204.001 Malicious Link

The file is a PDF containing embedded JavaScript, which is flagged by multiple heuristics including a critical detection for CVE-2007-5659. The JavaScript is heavily obfuscated but appears to be designed to exploit this vulnerability. The ClamAV detection 'Pdf.Exploit.Agent-36079' further supports its malicious nature. The primary attack vector is the exploitation of the CVE-2007-5659 vulnerability within the PDF document.

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-36079 critical CLAMAV_DETECTION

ClamAV detected this file as malware: Pdf.Exploit.Agent-36079
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.
String.fromCharCode low PDF_FROMCHARCODE

String.fromCharCode found — used to construct payload strings dynamically. Common in benign JavaScript libraries for codepoint manipulation, so this alone is informational; weaponised use is also caught by the dedicated fromCharCode-stage and exploit-shape rules. (matched inside decoded stream)
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
