Off topic: Problem with Google Groups password security?

Apprarently someone changed my password for my Google Groups account.
So I changed it. But then it got breached again, so I had to change it
again.
Anyone else have this problem?
I only use this account to post to Usenet so I'm not too terribly
concerned about that aspect of it. But it is curious that when I was
selecting my password the indicator to show the degree of security of
the passward listed it as "strong", which I presume means hard to
crack.
Are there automated programs out there used just to crack passwords
on Google Groups? What would be the purpose of those password
programs? I haven't signed up for a Gmail account. Perhaps such
programs would be useful because your Google Groups account can be
used as your Gmail account? Or can be used to access your Gmail
account?
