MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.005 Visual Basic

The file is an Excel spreadsheet containing a large list of mobile phone models and associated text, presented in a way that suggests a sales or pricing list. The presence of an Auto_Open VBA macro, detected by heuristics, indicates that the document is designed to execute malicious code upon opening. The macro likely serves to further the phishing or scam objective by displaying this content and potentially downloading additional payloads or redirecting the user. The ClamAV detection 'Doc.Macro.Laroux-5893719-0' further confirms its malicious nature. Embedded phone numbers and a QQ ID are present, likely used for communication or as part of the scam.
