MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The document contains a lure suggesting the user open an embedded package disguised as photos. Heuristics indicate the use of ShellExecute, LoadLibrary, and GetProcAddress APIs, commonly used by malware to execute or load malicious code. The presence of an embedded OLE package (ole10native_00.bin) further supports the delivery of a secondary payload. The document body's Portuguese text translates to 'Embed Package A slide of my best photos. Aaah and to open it just open my photo. Kisses ;*', reinforcing the social engineering aspect.
