Global internet authority ICANN that allocates IP addresses and domain names for the internet has reportedly been hacked in late November.

The hackers were able to breach a wide range of user information including real names, addresses, emails, telephones and usernames. They accessed internal emails, a members-only Wiki page containing public information, the WHOIS portal (used to look up who registered a particular domain), and the organization's Centralized Zone Data System (CZDS).
ICANN said, “The hackers also accessed the passwords of users. However, the passwords were encrypted.”
