Microsoft has added XLM macro protection for Microsoft 365 customers by expanding the runtime defense provided by Office 365's integration with Antimalware Scan Interface (AMSI) to include Excel 4.0 (XLM) macro scanning. [...]
"The recent AMSI instrumentation in XLM directly tackles the rise of malware campaigns that abuse this feature," Microsoft said.
"Because AMSI is an open interface, other antivirus solutions can leverage the same visibility to improve protections against threats."

"The visibility provided by AMSI leads to significant improvements in generic and resilient signatures that can stop waves of obfuscated and mutated variants of threats," Microsoft added.
