Login redirect
Ms Roberts also provided details of other attacks including:
Ms Roberts added that there was evidence that at least 11 accounts had been hacked, but warned that many more could be affected.
"It's a reasonable assumption, and our working one, that the passwords of everybody that has logged since 6 August 2015, and possibly some time before that, have been collected," she wrote in a follow-up post.
Mumsnet has yet to determine how the hacks were carried out, but one theory is that a "cross site scripting" (XSS) attack was involved, in which code would have been added to Mumsnet's site to redirect the login process to computers controlled by the attacker.
That way the hacker would have been able to harvest the passwords of people as they typed them in.
Ms Roberts said Mumsnet itself stored users' passwords in a "high strength" encrypted form, so doubted its own database had been cracked.
As a precautionary measure, all the site's users will have to create a new password when they next log in.
In addition, members are being asked to check that the page they log in on uses a specific address - https://www.mumsnet.com/session/login.
A spokeswoman for the site said it currently has 7.7 million members.
