MITRE ATT&CK

The file is an OLE document containing VBA macros, specifically a Document_Open macro, which is a common technique for executing malicious code upon opening. ClamAV signatures indicate it is a known trojan. The document body presents a seemingly legitimate order confirmation, likely intended to trick the user into enabling macros. No specific IOCs like URLs or hashes were extracted from the provided evidence.
