Spammers move from China to Russia
Stricter rules on registering .cn domains leads to increase in malicious .ru domains.
A change in the rules of the organization responsible for registering .cn domains has resulted in a drop in the number of
spam messages referencing Chinese top-level domains, with Russian domains moving in to fill the gap.
Until recently, a large proportion of the URLs found in spam messages contained a Chinese .cn top-level domain;
these domains were both cheap and very easy to register, making them ideal for spammers.
However, in December the China Internet Network Information Center (CNNIC) - the organization responsible
for handing out .cn domains - changed its rules. It is now no longer possible to register a .cn domain
unless one has a bona fide business license. Meanwhile, the CNNIC has also announced that it intends to
verify previously registered .cn domains.
As soon as the new rules came into effect, the relative occurrence of .cn domains in spam messages dropped
significantly. Now, new research by Symantec has shown that .cn domains have almost completely
disappeared from spam messages. Instead, spammers appear to be turning to Russian .ru domains
to advertise their wares - on some days 40% of spam messages contain such a domain.
While the CNNIC's new regulations seem to have done little harm to spammers, the changes are good news for
the reputation of .cn domains and for the large number of legitimate users using such domains: they are now
less likely to see their emails and websites blocked by over-zealous filters. For the large number of genuine
businesses and end-users using .ru domains, one can only hope that similar stricter regulations will be brought
in soon.
