Try this Regex:

^(.)\1{7}

^ is the start of the line. You would get more matches otherwise.
(.) matches a character and captures it (in case the ^ is used, it becomes the first character)
\1 express that the captured character must occur there
{7} ... seven times (since the first one has been already matched, 7 out of 8 left)
