Microsoft warns of new technique to distribute macro malware that can evade standard virus detection. Researchers stumbled upon the macro technique in a Word file containing VBA project scripts with a sample of well-known malicious macro malware called TrojanDownloader:O97M/Donoff. Microsoft said the attacker stored commands inside the name of a macro button. Palo Alto reports 1.2 million instances of the Bartallex family of malware delivered via malicious macro documents this year. That’s up from last year with 100,000 instances of macro malware.
