ZixCorp Security Expert Available to Discuss Latest Information Released on DNS Attacks DALLAS, July 30
DALLAS, July 30 /PRNewswire-FirstCall/ -- Zix Corporation (ZixCorp(R)),
(Nasdaq: ZIXI), the leader in hosted services for email encryption and
e-prescribing, today announced that Nigel Johnson, Vice President of Business
Development & Product Management for ZixCorp, is available to discuss the
critical DNS (domain name server) flaw that was recently announced by
penetration tester, Dan Kaminsky, which exposed the security threat that
allows hackers to reroute emails and web connections to rogue servers.
There are two ways in which this DNS flaw, called a cache poisoning
attack, can be exploited. DNS translates the human readable addresses on the
Internet into the numeric addresses that computers use. Hackers can now tell
a browser to go to a website that looks like a person's banking site, even
though it isn't. For example, when a browser looks up the IP address for a
bank, it will get the wrong address and point to a site that looks identical
to that bank's website. This powerful attack can grab personal banking
information, including passwords.
There is a more insidious attack involving email. Once again, DNS
translates the domain name of the email address into computer readable form.
With this cache poisoning attack, the emails are routed to a false email
server where the messages are copied and then forwarded to the original
recipient. Nobody knows that their personal information has just been copied,
searched and the relevant information sold on the black market.
Johnson can discuss the specific mechanisms that can be used to attack
email content, as well as the black market value of the information that can
be garnered from email.
In addition he can discuss the benefits of encrypting email so that this
style of attack cannot be used to gather personal information. This attack
was first discovered 8 months ago -- how many more attacks have not been
published yet?
