For the laymen: update operating systems, browsers, and apps. And avoid doing sensitive stuff over Wifi networks other than your own (or from people or organisations that you fully trust, and the network must be password protected). Once this mess is cleaned up, the latter will be safe again. All you need to do for the cleanup is updating everything.

Neither does the use of an LLM mean you do not understand thoroughly what you submit. He doesn’t give a crap how the code was created, as long as you, the human (I hope), understand what you are submitting and can take accountability for it. You are still responsible for whatever crap comes out of an LLM, the same way that you are responsible for what comes out of the compiler. Doesn’t mean you shouldn’t use compilers or LLMs.
