MITRE ATT&CK
T1204.002 Malicious File

The sample is a PDF document that contains a heuristic firing for the CVE-2008-2551 C6 Messenger DownloaderActiveX exploit. This exploit is designed to download and execute a second-stage payload from a remote URL. The embedded URL 'http://artisanballoonz.com/system/system.exe' is highly suspicious and likely the payload delivery point. The document body contains numerous benign URLs, likely for obfuscation.
