I might be way off here but I noticed something today when I was vailidating my quotas.  A few users in the quota area are not in my group or passwd files see below.  I have listed what I feel are possibly groups made by my system being hacked?

The only reason I say is the obvious #666 and in my group file these do not exist

***************repquota -uga

#96       --      48       0       0             12     0     0
#526      --     212       0       0             53     0     0

Any Ideas on whay this could be and how I would remove them?

These may be old users removed from the system since.
You can find these files using the following command :

find / -uid 502 -o -uid 575 -o -uid 666 -o -uid 80 -o -uid 96 -o -uid 526 -ls

It might take a while if your disks are big.
I suggest redirecting the output to a file for later examination.

find / -uid 502 -o -uid 575 -o -uid 666 -o -uid 80 -o -uid 96 -o -uid 526 -ls > /tmp/fic
