The flaw at the core of the Internet that was recently revealed could be bigger than initially thought – and experts are concerned that ISPs around the world are not doing enough to counteract it.

Dan Kaminsky, the man who found the flaw, believes that almost one-third of the Internet may still be vulnerable to the flaw, which allows hackers to divert users to fake web sites where personal information could be stolen.
The flaw, which would allow hackers to get into the Domain Name System (DNS), insidious – so neither the user, the site owner or the ISP is aware that he's being misdirected.
Since the flaw was revealed in March, there's been at least one successful breach, with some AT&T customers directed to a fake Google site.
