MITRE ATT&CK
T1204.002 Malicious File

The critical heuristic firing for CVE_2008_2551 indicates the PDF exploits a known vulnerability to download a secondary payload. The embedded URL http://artisanballoonz.com/system/system.exe is highly suspicious and likely hosts the next stage of the attack. The document body was unreadable, but the exploit and the suspicious URL strongly suggest a downloader attack.
