MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as a legacy Excel formula macro virus, specifically 'Poppy by VicodinES' and 'The Narkotic Network'. The document body contains text that appears to be a timesheet or work log, likely intended to trick the user into opening and interacting with the malicious content. The presence of VBA/macro-related heuristics and the embedded text strongly suggest an attempt to execute malicious code via Excel formulas.
