Global co-operation on cyber security is long overdue

Security researchers recently revealed that a previously unknown hacker group carried out a series of attacks on government agencies in 13 countries by redirecting agency computers to hacker-controlled servers. This happened through the manipulation of domain name system (DNS) infrastructure. And it followed a US Department of Homeland Security alert disclosing a global campaign, subsequently linked to Iran, to redirect internet traffic and steal sensitive information also by compromising DNS infrastructure.

The DNS is an attractive target because it serves as a global address book, translating internet names we know into IP addresses that computers can recognise. The infrastructure supporting DNS is maintained by a number of core companies that administer internet domains, register new domain names, and host DNS “lookup” services which convert those domain names into IP addresses.
