T1204 Malicious Link
T1059.003 Windows Command Shell
The sample is a malicious OLE document that exploits CVE-2006-6456 via a malformed table SPRM. It also exhibits suspicious cmd.exe invocation, suggesting it attempts to execute a command. The PEB access heuristic further indicates potential evasion or malicious code execution. Due to the lack of document body or script content, the exact payload and delivery mechanism remain unclear, but the exploit and command execution point to a downloader or initial access stage.
