The use of various runtime library string-manipulation routines for copying or processing strings in some way, while letting the routine determine how much data should be written.

b.

The use of a fixed-size buffer to copy a user-supplied string into.

c.

The use of ASCII characters that would become a workable shellcode once converted into Unicode.

d.

The use of JA (jump if above) instead of JG (jump if greater) for the comparison.
