MITRE ATT&CK
T1059.005 Visual Basic

The file is identified as a legacy Excel formula macro virus, specifically 'Poppy by VicodinES' and 'Narkotic Network'. The embedded text and script fragments indicate an attempt to infect other workbooks and deliver a payload, likely related to the 'Hydrocodone/APAP 10-650 For Your Computer' lure. The presence of VBA macro indicators and the specific virus markers strongly suggest malicious intent.
