Microsoft has been using an integration between its Antimalware Scan Interface (AMSI) and Office 365 to knock out macro malware for years, but its successful efforts to take out macro scripts written in Visual Basic for Applications (VBA) ended up pushing attackers to an older macro language called XLM, which came with Excel 4.0 in 1992.
