Windows And this is part two of the story: Microsoft has just confirmed the next version of Windows NT (referring to it as NT for clarity's sake) will be available for ARM - or more specifically, SoCs from NVIDIA, Qualcomm, and Texas Instruments. Also announced today at CES is Microsoft Office for ARM. Both Windows NT and Microsoft Office were shown running on ARM during a press conference for the fact at CES in Las Vegas.

This fact is only relevant to this topic becasue someone stated that Windows for ARM would initially be free of malware, which is true, but my point is that there is nothing about ARM that would mean that this remains true for long.

It is "made-for-Windows", and "distributed via closed-source binary executables", that characterises 99% of existing malware. x86/x86_64 versus ARM really doesn't come into the picture. Just as Microsoft can fairly readily make a version of MS Office for ARM, so can malware authors also rapidly make an ARM version of their trojan malware in a similar fashion. It merely has to become worth their while.


Actually, it occurs to me that if Windows on ARM does gain appreciable market share, such that it does become worthwhile for malware authors to port their Windows malware (which is almost all malware) to ARM, then existing virus databases will be useless. Any re-compiled-for-ARM malware will have a different binary "signature" than the x86/x86_64 malware does.

This will open up the beginning of a "golden age" for Windows-for-ARM malware, until some lengthy time later when the antivirus and anti-malware scanner authors can build up a similar signature databse for the new for-Windows-for-ARM malware binaries.
