Creating fake dialogue boxes and windows is nothing new, that has been around forever. Maybe using css to determine the os/browser and mimic each one’s style is the new concept. I’ll believe it when someone can show me a webpage that proves it live.
This goes way back to the
bad old days of 90s web popups that attempted to look like Windows dialogs.
Luckily for everyone the spammers couldn't resist the temptation to throw in a few brightly coloured police tape GIFs, radiation symbols, typos, bold fonts in about 6 sizes and otherwise generally spoil the illusion.
Anecdata, but I think this method is popular with Steam phishing sites. I have received a few links that mimicked the Steam web login prompt with a Windows window appareance.
