Excel-based malware has been around for decades and has been in the limelight in recent years. During the second half of 2020, we saw adversaries using Excel 4.0 macros, an old technology, to deliver payloads to their victims. They were mainly using workbook streams via the XLSX file format. In these streams, adversaries were able to enter code straight into cells (that’s why they were called macro-formulas). Excel 4.0 also used API level functions like downloading a file, creation of files, invocation of other processes like PowerShell, cmd, etc.   With the evolution of technology, AV vendors started to…
