What makes Intel processors more exploitable than PowerPC? Is it just that there are currently more?
It's the Windows software... not the Hardware....
Coding for a PowerPC is completely different from coding for x86 (the instruction set that Intel and AMD processors use.) Since most exploits are released for x86 platforms, it means the coders are familiar with x86 coding, and are therefore now familiar with the CPU-related coding for Apple computers.
However, it's just alarmism, since exploits run on Windows, not x86. OS X isn't Windows.
Nothing... if it were more exploitable then all the software fixes and patches and anti-viral apps wouldn't be able to help. The processor just does that... process what's given it in the correct syntax. It's the ability to inject foreign code into the syntax or to interupt the giving of that code to the processor that is at issue... a sofware issue.
Absolutely nothing - that's what the reply right below the article is trying to say. The processor has ZERO to do with vulnerability - it's the OS and related software that provides the vulnerabilities.
