MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The file is an XLS document containing VBA macros. Heuristics indicate the use of WScript.Shell and the Shell() function, suggesting the macro attempts to execute external commands or download additional payloads. The ClamAV detection name 'Xls.Dropper.Agent-7683382-0' further supports its role as a dropper. The document body content is obfuscated and does not provide clear user-facing lures.
