Yeah, computers tend to hear differently than humans do, so you can cater some sort of message to them that humans won't process but they will. See https://www.mdpi.com/2079-9292/12/8/1928 https://www.mdpi.com/2079-9292/12/8/1928 as an example. They can also be embedded into songs so that humans hear one thing but the computer does something different: https://www.usenix.org/conference/usenixsecurity18/presentation/yuan-xuejing https://www.usenix.org/conference/usenixsecurity18/presentat... There have also been attacks on computer vision systems (like in cars) that can make them suddenly brake or misidentify a lane or street marker, etc., but in ways not obvious to humans: https://adversarial-designs.shop/blogs/blog/adversarial-patch-attacks-on-self-driving-cars https://adversarial-designs.shop/blogs/blog/adversarial-patc... or to fool facial recognition systems into thinking you're someone else (in a way that won't fool anyone who actually knows you). And more broadly, any sort of obscured malware tries to deliver a malicious payload while pretending to be something else to the human who runs it.
