MITRE ATT&CK

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

The file is identified as malicious by ClamAV with the signature Doc.Downloader.EmotetExcel02226-9938630-0, indicating it's a known Emotet downloader. The presence of a Workbook_Open VBA macro, which calls CreateObject and references Wscript.Shell, strongly suggests it's designed to execute arbitrary commands. The macro attempts to construct and execute a command line that includes multiple URLs, likely for downloading and executing a secondary payload. The reconstructed URL string is "http://fOur.renovatio.ltd/wp-includes/KGzoB0zsRKZqEjE/ , http://adulterfriendinder-adultfriendswith.com/wp-includes/mfdoublepenetration/0pcEejJPfwM/, http://jweller.fameit.com/wp-includes/wPK7z9cEcwCUg/, http://arcgakuin-dev2.sukob.com/wp-admin/Z464/ , http://gardenfil.com/wp-content/Ef/, http://moneymagnetentertainment.com/pz66t8y/Bd0sR0hAD8mHibNjRk/, http://hostfeeling.com/wp-admin/DidtoZoK2EEc7BWxyhh/". Additionally, a suspicious batch file path 'c:\programdata\uylcsekn.bat' is present.
