This post today on WHT from SoftWareRevue probably qualifies as the first official acknowledgement of the hack:
Today, 01:18 PM #156 SoftWareRevue
We have identified a potential unauthorized access that may affect our users’ personal information. We have been working diligently around the clock with a third-party forensics team to confirm the nature of the access and mitigate any potential risk to our users. Over the past 82 hours we have implemented a variety of security protections and are preparing to communicate with all affected users once we have sufficient information to share.
Implementing security protections on your own sites is good of course, but after doing a few searches on LeakedSource tonight I've decided that chopping off employees hands so they can't fill out registration forms and use their company email address to register on other websites might also be a very good idea to improve company security...especially since some of those employees no doubt use the same password / company email combo everywhere which creates a security problem when the sites they've registered on get hacked and their login info gets spilled all over the web.
A few examples of leaked databases to illustrate why you should take the security precaution of discouraging your employees from using their company email address to register on other sites and why you should expressly forbid them from using a company email address when the registration on the other site is not business related (
note: LeakedSource limits their search results to the first 200 results so the following lists aren't even close to being complete lists of the number of times employees have had accounts associated with a corporate email address hacked)
Example 1: Hostgator employees using a company @hostgator.com email address:
