These problems are showing up on a iPad, which is supposed to be pretty bullet proof when it comes to local hacking. Everything I’ve read to date has indicated that the source of these “Congratulations...” malware has been bad guys managing to insert their code into web pages at the source server level where the server hasn’t been properly patched. I’ve done a bit more reading, and it seems that they also manage to insert forced redirects at the browser level. I’ll try resetting Safari and, but the worst case will be restoring the iPad to factory defaults and loading in only the apps I really use.
