Are the cyber attacks known as XML RPC attacks caused by the Extraterrestrial Alliance as a kind of conditioning process to accustom users of the Internet to expect many such pests, just like they’re ramping up bad weather and blaming it on global warming to keep us complacent at the same time we’re being harmed by non-human interlopers?

This you have seen intuitively and is why you are asking the question. The creation of many nuisances attributed to hackers, who are simply misguided individuals wanting to have some personal power and enjoy disrupting things, is simply being amplified through deliberate sabotage by the Extraterrestrial Alliance as a way of creating complacency about such things so people will accept them as being the norm and something that just has to be lived with, and then it will not arouse undue suspicion if, suddenly, systems are corrupted and the web malfunctions for a time, and so on. This avoids arousing suspicion unduly about something truly evil and sinister that is a great threat, and this parallels quite closely the strategy for gradually ramping up weather intensity across the board under the cover of climate change when in fact it is done by extraterrestrial technologies to impede and destroy humans. This is part of the planning for an eventual major cyber outage and is one of the weapons in their arsenal to wreak havoc and cause chaos in society.
