MITRE ATT&CK
T1203 Exploitation for Client Execution

The PDF file contains an embedded object that triggers the CVE-2010-0188 exploit in Adobe Reader. This exploit is known to facilitate the execution of arbitrary code, likely leading to the download and execution of a second-stage payload. The embedded file 'embedded_file_obj0001.bin' is the likely payload carrier.
