Re: You want a ransomware infection?
Hopefully they are not requiring macros to be enabled in this spreadsheet - NCSC advice is that macros are disabled, if that is not possible, consider code signing for approved files or limit execution to only those that need it. Windows ASR and AMSI also worth looking at - vba is a big attack vector.
