MITRE ATT&CK

T1566.002 Spearphishing Attachment T1204.002 Malicious File

The file is a PDF document identified as malicious by ClamAV due to an obfuscated object name. It also contains an embedded file, which is a common technique for delivering secondary payloads. The document body is heavily obfuscated and unreadable, suggesting it is not intended for user interaction but rather to trigger an exploit. The presence of an embedded file and the obfuscation strongly indicate an attempt to exploit vulnerabilities and download further malicious content.
