T1204.001 Malicious Link

The PDF contains a critical heuristic firing for CVE_2008_2551, indicating an exploit for the C6 Messenger DownloaderActiveX. This exploit likely facilitates the download of a secondary payload from the embedded URL http://artisanballoonz.com/system/system.exe. The document body was unreadable, but the exploit and URL strongly suggest a downloader attack pattern.
