Therefore, this DoS attack isn't a big deal. It's easily preventable, rarely effective, and relatively harmless (all you have to do, if it hits, is redial). --Brett Glass
I have tested this out here locally, as well as with the help from a few other people onlin and it seems that 6 of 9 modems have been affected. I would hardly call that 'rarely effective', relatively harmless yes, but it seems to be a large percentage. I am interested to see more results as too how wide spread this is.
