Microsoft's chief software engineer, Lee Holmes, said that Windows 10 applications will now be able to connect to installed anti-virus platforms to better combat malware.
Holmes said the feature Antimalware Scan Interface (AMSI) of Windows 10 will allow apps and services use different anti-viruses to discover malicious activities in the system memory.
As Holmes states, most anti-malware they can read signatures of suspicious activity, but if encryption techniques like XOR are used, security applications fail as malware appears benign.
Attempts to date, at best, did not detect the attacks that occurred in the memory and, at worst, they had false positive results that stopped legal proceedings.
Holmes said, "Or the antivirus engine checks files opened by the user. "If the malicious content is only in the memory, the attack may go unnoticed."
"Malicious scripts can go through various paths to hide them, but in the end they should feed the scripting engine with a simple, non-obscure code. At this point, the application can now call the new Windows AMSI API and request a scan of unprotected content.
"Any application can also call a registered anti-malware engine through AMSI and edit the submitted content."
Holmes called on all application developers to add to their applications the ability to use AMSI.
As the expert mentions the new feature can be extended to "catch" the malware on instant messaging or gaming platforms; video plug-ins and more.
"There are so many more opportunities - this is just the beginning," he said
Note that Windows Defender, Microsoft's anti-virus platform, thanks to AMSI technology able to detect malicious scripts with XOR.
