事態嚴重嘍!
我初步認為是某個 registrar 被黑掉,
而可以透過被黑掉的 registrar 去修改任何 *.com *.net 的 whois info.

$ whois baidu.com

Whois Server Version 2.0

Domain names in the .com and .net domains can now be registered
with many different competing registrars. Go to http://www.internic.net
for detailed information.

To single out one record, look it up with "xxx", where xxx is one of the
of the records displayed above. If the records are the same, look them up
with "=xxx" to receive a full display for each record.

似乎也突顯出, 網域名在註冊/修改DNS server時, 檢查機制方面的漏洞.
以前跟 ARIN 和 APNIC 有聯繫時, 就明顯感覺他們的差距,
一個太過信任, 一個則很嚴謹.
經過這次事件, 應該會有些修正了.
