MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy WordBasic macro virus, specifically identified by the 'TOOLSMACRO' marker. ClamAV detection as 'Doc.Trojan.Eraser-18' further confirms its malicious nature. The document body contains obfuscated strings and references to macro execution, indicating it's likely designed to download and execute a secondary payload.

  • Legacy WordBasic macro-virus markers high OLE_LEGACY_WORDBASIC_MACRO_VIRUS
    OLE Word document contains legacy WordBasic auto-execution macro markers such as AutoOpen plus ToolsMacro/MacroFile/fileMacro/globMacro or named historical macro-virus strings.
