MITRE ATT&CK

T1059 Command and Scripting Interpreter T1059.001 PowerShell T1055 Process Injection T1055.012 Process Hollowing

The PDF file contains a critical heuristic firing indicating a Base64-encoded PE payload. The payload utilizes process injection APIs such as VirtualAllocEx, WriteProcessMemory, and CreateRemoteThread, suggesting it's designed to inject malicious code into a legitimate process. The exact nature of the payload is not detailed, but its embedding within a PDF points to a common delivery method for malware.

Heuristics 1
