Summary:
Spammers have been abusing generic top-level domains, released by the Internet Corporation for Assigned Names and Numbers earlier this year, in hit-and-run spam attacks.
The Symantec Global Intelligence network has detected a significant increase in hit-and-run spam attacks (sometimes referred to as 'snowshoe' spam attacks) from .club domains in the last 24 hours. Earlier this year the Internet Corporation for Assigned Names and Numbers (ICANN) released a number of generic top-level domains (gTLD), with .club among them.
