An intruder with a reasonable knowledge of the base design (eg Schlage, Yale, Kwikset handle retainer) and the right tool (or all too often, some bits of debris/common office products) could likely remove any handle that allows itself to be removed from that outside. A handle set with the knob/lever crimped or otherwise permanently retained by an exterior cover plate where the cover plate is then secured by catches or screws only accessible from the inside face of the door prevents such surreptitious attacks.
Lever/handle sets which contain the lock cylinder in the knob/lever but include a disassembly catch for the outside handle/lever would allow an intruder to surreptitiously (and technically, non-destructively) gain access to the latch components.
Any handle set which involves removing (or attaching) the lever/knob/handle separately from the escuton/housing cover during the installation or field service process is likely to present this type of vulnerability.
