MITRE ATT&CK

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

The file is identified as malicious by ClamAV with a signature indicating it's a downloader associated with Emotet. The VBA macros contain obfuscated PowerShell commands that reconstruct a URL for downloading a second-stage payload. Specifically, the script reconstructs the following URLs: 'http://everisyoglobal.evens.com/wordpress/ZYZ1wZJFu34Bbj/', 'https://demo.nhabe360.com/arthroceel/ufYiTla2O/', 'https://theoutsourcedaccountant.com/prb8h/NeXCc0ccs/', 'https://gms.gdtnbvu.club/gash/M9tOuTEGUOKsRNxd7GVyu9o/', 'http://forwardmar.club/imp/J9rT5BUF4ZCQpaVMDfpo/', and 'https://brashimix.com/l3pkut/fuWgsoZsHm3ddKviIS7XEF2/'. The script also attempts to write to registry keys related to persistence, specifically 'HKCU\Software\Microsoft\Windows\CurrentVersion\Run\IAccessible2Proxy'.
