ICANN Addresses Network Traffic Misdirection

With the number of top-level domains available on the Internet continuing to grow, the Internet Corporation for Assigned Names and Numbers is seeking ways to reduce the risk that traffic intended for network destinations within an organization may inadvertently be sent to the public Internet via the Domain Name System (DNS). There are now roughly 1,400 top-level domains, which makes it increasingly possible, says ICANN, that some of those domain names are being used by organizations for their corporate intranets. This sort of name collision can result in communications intended for intranets to be sent to the public Internet. Some information might, for example, include sensitive data or proprietary corporate information. ICANN—which is responsible for allocating IP addresses and managing the DNS—commissioned JAS Global Advisors, a risk-management consultancy, to issue a report including recommendations on how to address the issue. One recommendation was designating 127.0.53.53, an unusual IP address, to alert organization’s administrators in the event a name collision was eminent. The report’s authors say the return of such a unique address would likely cause the administrator to look up information about it that would enable her to determine the root of the problem.

Problems Continue for Sites Hacked by Syrian Electronic Army

The New York Times and Twitter were among the sites hacked Tuesday by the Syrian Electronic Army (SEA), causing problems that are persisting in what is reportedly the group’s most damaging attack to date. The group of hackers—aligned with Syrian president Bashar al-Assad in his two-year civil war -- altered numerous websites’ domain-name-system information, which resides on the same third-party site. The SEA gained access to Melbourne IT, the domain registrar’s, database, then edited the DNS information so that it would direct unsuspecting Web surfers to sites hosted by the hackers, who publicized their attacks using social media. This is the second time this month that the New York Times site has gone offline. The first was reportedly the result of an unspecified internal issue. (BBC)(TIME)
