MITRE ATT&CK

T1204.002 Malicious File

The PDF contains embedded JavaScript and a critical heuristic firing for CVE-2008-2551, indicating it exploits a vulnerability to download a payload. The embedded URL 'http://artisanballoonz.com/system/system.exe' is highly suspicious and likely the secondary payload. The PDF's structure also suggests it's designed to trigger an exploit upon opening.

Heuristics 4

C6 Messenger DownloaderActiveX exploit critical CVE exact CVE_2008_2551

PDF stream bytes contain HTML/ActiveX content configuring the vulnerable C6 Messenger DownloaderActiveX control with propDownloadUrl and propPostDownloadAction=run. This is the published exploit shape for CVE-2008-2551.
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.
Optional Content Group with action trigger low PDF_OPTIONAL_CONTENT

Optional Content Group (layer) co-occurs with an action trigger — content can be selectively hidden from viewers or scanners while the action still fires on open
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
URL http://artisanballoonz.com/system/system.exe
