Most malware is packed and/or obfuscated. I'd imagine this defeats fingerprinting relatively handily since the binary is rewritten. I'm sure this technique is used to catch particularly dumb adversaries, but against anyone with a hint of operational security it wouldn't work at all. Moreover, what's stopping a determined adversary from rewriting the binary with a signature that matches another person? Using this as a targeting method would have a lot of collateral damage.
