I found something interesting in my Cache Dameons folder today and started to give me a scare- please take a look and lmk what you think.

First, to accomplish what you describe that hypothetical user would require hands-on possession of that Mac. The most fundamental element of security is physical: keep your Mac physically inaccessible to unauthorized users of it. Physical possession makes a number of potentially unauthorized and nefarious actions possible. It would also be a crime to do that, lacking a warrant issued by a court, at least in the United States.

Next: even if someone were to physically possess that Mac, he or she would need to provide its firmware password before being able to boot single-user mode.

Next: even if someone were to boot single-user mode, that someone would need to provide the Mac's FileVault password before its startup disk (hard disk / flash memory / "fusion drive") could even be mounted. Without that password, a hard disk encrypted with FileVault can be used for no purpose unless and until it is erased, which leaves nothing but random data behind.

Next: Macs with the T2 Security Chip convey even more protections with options described in Secure Boot.

Next: The particular Launch Daemon that uses the properly list you're describing comprises a fundamental aspect of macOS User Account creation and control. It is not subject to exploitation any more than macOS itself, and macOS "Catalina" is by far the most secure consumer-grade operating system there has ever been in the history of mankind or whatever may have preceded it.

Despite those facts I understand you're concerned about your Mac becoming "hacked". That's understandable, but a more comprehensive answer requires explaining just what that term means to you. "Hacking" has a bunch of different connotations encompassing the full range of benevolent to benign to malicious. Bear in mind that an enormous number of Mac users willfully install things that exist for the sole purpose of constantly harvesting and uploading personal information from their Macs, in the same manner as a "computer virus" would, if such a thing were to exist on a Mac, which it doesn't. They do so willfully; almost gleefully. Merely suggesting they reconsider that practice tends to annoy them. It's called Google.

Finally: there are multitude of simpler and easier ways of lifting personal information that don't even involve a Mac.

No, I won't call you crazy; I'll just call you naturally inquisitive and cautious. But there's no reason to believe any of the information you posted is any indication of malicious interference. I have looked at everything you posted, and there is simply nothing unusual or reason for concern.

MobileDevice for example is a name Apple typically uses to identify various services for iOS devices that connect to and sync with your Mac, and those files exist on the Macs I use.

I would caution you about opportunists that seek to convince you of the need to buy whatever product they're peddling claiming to protect your Mac from whatever evils—real or imagined—may exist. They'll exploit your concerns and even use the information you posted to convince you something's wrong when it isn't. Those opportunists are the real threat you should fear.

I can't get too excited about Trojans. By definition that's something users are deceived into installing, and usually that deception leverages a desire to illegally obtain something without having to pay for it. It's my opinion that people who do that get what they deserve, but set that opinion aside for now. Everything you install on a Mac requires a deliberate and overt action, and macOS provides various degrees of warnings if that something was obtained from a potentially untrustworthy source. Those warnings should always be taken seriously. Things that affect a Mac system-wide always require Administrator authorization. Then there's macOS itself, recent versions of which simply cannot be altered, even with Administrator authorization.

Then consider "Intego" is one of the worst pieces of garbage anyone could inflict on a Mac. Installing it made mine nearly unusable. No knowledgeable Mac user would tolerate it. But set that aside also. Set aside its purpose of frightening people into buying their junk too. The Intego article describes a hypothetical Trojan that never manifested in affecting Macs in any widespread manner. Apple responded by blocking it with its XProtect service anyway, as they do when such exploits arise—even hypothetical ones.

It's one thing to create a clever Trojan in a laboratory setting and proclaim its success. It's quite another to actually deploy one and accomplish anything meaningful. You can come up with hypothetical Trojans all day long. It would take me about thirty minutes to develop one myself, but that's only because I have no extraordinary programming skills.

Then there's the fact it's eight years old and as many macOS versions out of date.

Summary: Forget about "OSX Crisis". The sky is perpetually falling for some people.

All those files in your screenshot are totally normal and present with all recent macOS versions. They are used in conjunction with iOS device syncing.
