The file is identified as a malicious PDF dropper by ClamAV and an ML classifier. It contains an embedded URI pointing to a PDF file on 'gorillawalker.com'. The document body is heavily obfuscated and unreadable, but the presence of the external URI strongly suggests the intent is to trick the user into downloading and opening a secondary malicious document.
