My Kutt was hacked! How? Check yours!!

@BrutalBirdie thanks! Merged and pushed an update.

Also, https://docs.cloudron.io/apps/kutt/#registration

@girish Perhaps we should consider looking at all apps across the portfolio for open signups (like VaultWarden which bit me a few weeks back) and disable them as part of our app onboarding?

[girish]

@doodlemania2 registration is almost always disabled by default. But some apps like Kutt won't allow anyone to sign up, if registration is disabled.

@timconsidine this got me too. was looking for a shortener i could iframe into a client dashboard so through kutt up. I don't know how bad or if im still infected but a day or two after setting it up, all my links started to time out - they were being blocked by my browser. at the same time, I lost admin access on a totally different wp site :S i deleted kutt before i thought to investigate.

definitely reminded me as to the importance of security. i still cant get my orginal link shortener (installed on a lamp stack) to work - im worried i got the domains banned or something

[timconsidine]

@plains-digital may not be be as bad as you think
I appealed against some blocks and responded to incoming abuse notifications and got it cleaned up.
Kutt works well so don't be afraid to try it again - just turn off registrations.

@timconsidine my clients domain is STILL pointing at two dodgy IPs

[timconsidine]

@plains-digital another thread here about Netcup had some comments about cleaning ip addresses.

hey @timconsidine this just happened to me today.

There was a couple of dodgy URLS probably because of the registration option I didn't check at install. I have the service down, but I wonder if there's any way to check and remove the spam users before getting the service up. I don't know how to explore the postgres db.

@chetbaker with 8.0.0, we have a new app notes feature. The notes get prepopulated with installation checklist.

As for postgresql, it seems to be quite easy to navigate:

Thanks @girish. Just for the record, the command to remove entries is (after identified the users on the users table using the command @girish shared (in my case 4, 5, 6 and 7):

DELETE FROM users WHERE id IN (4, 5, 6, 7);
