MITRE ATT&CK

T1059.001 PowerShell T1059.003 Windows Command Shell T1204.002 Malicious File T1105 Ingress Tool Transfer

The sample contains VBA macros that execute a Workbook_Open event, which in turn uses Wscript.Shell to run a batch file and a VBScript. The VBScript is obfuscated but appears to download and execute further payloads from multiple URLs. The ClamAV detection name 'Doc.Downloader.EmotetRed02220-9938909-0' strongly suggests the Emotet family. The script attempts to download from the following URLs: 'http://fulleyness-safety.com/-/P6x/-/', 'https://nabajyotifundation.com/da8uc7jo/4Za/', 'https://dwmasster.com/wp-content/eBH2UFY2/', 'http://formula8020.com/cs/56Dzi0P/', 'https://calad-formation.fr/r3x94z/kgZ9OGCi/', and 'http://lorma8020.com/cs/56Dzi0P/'.
