comment Difference between Unix OS Types
OSX is derived from Mach 2.5, with a thin layer of BSD compatibility on top. I'm not so sure it's FreeBSD, it might actually be BSD 4.4 lite or whatever that last BSD release was.

comment Updating PHP to Gaurd Against Mayhem Malware
@Boundless - the code I got, which is identical to what Virus Bulletin reports (virusbtn.com/virusbulletin/archive/2014/07/vb201407-Mayhem) only uses simple PHP - fopen()/fclose() is about as exotic as it gets. The dropper code does call system(), which runs a command via the shell, so you could potentially disable system(): cyberciti.biz/faq/… Like I wrote above, the PHP it uses is nothing special.

comment Low level system call
@saurav1405 - you can look at the source to find out, but for Musl libc, you can look at http://git.musl-libc.org/cgit/musl/tree/src/unistd/read.c - it's in C, but it uses a macro that I trace to the file src/thread/x86_64/syscall_cp.s. The macro expands into in-line assembly. So I'm not sure what to call it: "written in assembly" or "written in C with a line or two of assembly". Probably the latter.

comment What's the difference of the Userland vs the Kernel?
@r004 - see edits. I used wireless cards, but driver software makes SATA, SCSI and IDE disks all look the same too, despite vast differences in what they can do.
