Hackers have recently released software code that could be used to exploit that serious flaw in the Domain Name System (DNS). The DNS is used to route traffic on the Internet, making sure it gets to the right computer.

Using this bug, a hacker could launch a phishing attack that is nearly impossible to detect. The only way to prevent such attacks is for your ISP to install the latest DNS server updates. This takes time.

The bug was accidentally disclosed earlier this month. But it had been known for months, as the big DNS software houses worked to fix it. These include Microsoft, Cisco and the Internet Systems Consortium (ISC).

There is not much you can so to protect yourself against this type of attack, except to be vigilant. Examine a site closely before giving sensitive info, and make sure it is secure. Minimize your use of online banking, for now. I’ll keep you posted.
