One day i was looking at some logs* and the webserver was asked for rom-0 file.
It was no issue 404 i think, so i did not use a microsoft search engine and discovered its a router flaw which with a tool means you can extract the router password.
It means that software from brand name router companies is now a problem if they dont want to fix it. Such attacks make sense to certain people ** (my blog).
* not exciting ** not criticism of bitcoin but the small percentage of people.
